The Big O Tribute Race is an annual kart racing event that began in the late 2000s as a memorial for Otis “Bo” Merritt – a beloved engine builder and racer in the karting community. Merritt, who passed away in May 2008, owned Merritt Machine Shop in Gastonia, NC and was well-known for manufacturing go-kart engines. Affectionately nicknamed “Big O” by friends and racers, Merritt’s legacy of craftsmanship and passion for karting inspired the creation of this tribute race. The inaugural “Big O” memorial race was held around 2008, and it has been held annually ever since, growing in prestige each year. Initially referred to as the Otis Merritt Memorial, the event quickly earned the moniker “Big O Tribute” in honor of Merritt’s nickname.
From humble beginnings, the Big O Tribute has expanded into one of the most anticipated dirt kart races on the calendar. By 2014 (the 7th annual event), it was already attracting dozens of entries from across the country. Over the years, it has evolved into a multi-day racing festival while staying true to its purpose: honoring the memory and contributions of Otis “Big O” Merritt and celebrating the spirit of karting he embodied.
Purpose and Honoree of the Tribute
The Big O Tribute Race is fundamentally a memorial event dedicated to Otis “Big O” Merritt. Merritt was a revered figure in southeastern kart racing known as “the man of the modifieds” for his expertise with high-performance kart engines. He was widely respected for helping fellow racers – if he couldn’t make a part you needed, “he would get it made for you,” as one remembrance noted. Upon his passing at age 71, the racing community honored him by establishing this annual race. The purpose of the event is to celebrate Merritt’s legacy, bringing together racers who appreciate the innovations and competitive spirit he brought to the sport.
Each year, opening ceremonies and promotional materials reinforce this memorial purpose. The “Big O” name itself keeps Merritt’s presence at the forefront – as one guestbook tribute stated, “Big O you will truly be missed… you will never be forgotten”. While Otis Merritt is the central honoree, the Big O Tribute has also occasionally incorporated additional tributes. For example, special “throwback” kart paint schemes have been run to honor other local racing figures during the event. These gestures show how the Big O Tribute has become a platform to recognize not only Merritt but the broader heritage of kart racing in the region. At its core, however, the event’s mission remains focused on paying tribute to Otis “Big O” Merritt’s memory and influence on dirt karting.
Race Categories and Formats
The Big O Tribute is known for its wide range of kart classes and a packed multi-day schedule. Races are typically divided by age group, engine type, and skill level to accommodate everyone from young kids to veteran racers. Key categories and format features include:
Youth Classes: The event encourages the youngest racers with classes like Rookie Red (often called “Red plate or future stars” for ages ~5–7). In fact, the promotion for 2025 highlighted the first “Juice Box” entry and emphasized “seeing the kids of the future on the track!”. Beyond the novice level, there are Pro Junior divisions usually split by age (e.g. Jr. 1 Green Plate for ages ~8–10, Jr. 2 Purple Plate for 10–12, and Jr. 3 Blue Plate for 11–15). These junior classes run on small engines (often 4-stroke OHV “clone” engines with restrictive plates by age) and have their own feature races and prizes (sometimes with guaranteed winnings for the Pro Jr. categories).
Adult Clone Classes: Clone engine classes (using 4-cycle OHV engines) are a staple. The Semi-Pro Clone, and Pro Clone classes. There are usually Medium, Heavy, and Super Heavy divisions to ensure fair competition by weight. These classes often feature significant purses (e.g. $1,000 to win in some Pro Clone categories) to attract top clone drivers.
Limited and Modified Classes: To honor Big O’s roots in high-performance flathead engines, the event runs Flathead Modified classes. A “Limited Modified” (Flathead up to .080" overbore) class and a Pro Limited are usually on the schedule. These are technical Briggs flathead classes with engine build rules, offering substantial prizes (e.g. $2,500 to win Pro Limited in past events). There is also a Flathead Open Modified division – effectively the marquee “Big O” race itself – where highly built flathead engines up to 14.5 cu. in. compete with minimal restrictions. The “Big O Open Modified” class typically runs at #375 lbs and has the largest payout of the weekend.
UAS / Open Classes: The Big O Tribute is famous for its Open division racing. It often hosts a round of the Unlimited All-Stars (UAS) series, inviting karts with two-stroke and high-displacement engines (dirt bike engines, twins, etc.). UAS karts – the fastest in karting – run under their national rules (14.5 ci limit for overhead valve engines, etc.). The UAS and Open classes are a big draw for engine builders and “outlaw” kart racers, showcasing extreme horsepower. For example, on some Friday nights an OHV Open class and UAS shootout are held as preliminaries.
Champ Kart and Other Classes: Many years also include Champ (cage) kart classes or local option classes. In 2016, a Limited Champ Buggy race was on the Friday schedule. The event coordinators ensure there is “a full schedule of stock classes running also, so if you want to race something, you can” – meaning clone classes for hobby racers are available alongside the pro classes.
Format: The Big O Tribute is usually a two-day event. Historically, Friday is for practice and preliminary races, while Saturday hosts the main events. For instance, gates might open midday Friday with practice in the evening, followed by special races (e.g. shootouts or qualifying heats) Friday night. Saturday starts in the morning with more practice or qualifying, then moves into feature races for each class by afternoon and evening. Major classes like the Big O Open Modified often have qualifying time trials or heat races to set the field, B-Mains (last-chance qualifiers) for those on the bubble, and then an A-Main feature. (In 2024, for example, the Big O Tribute feature had enough entries to warrant a B-Main before the final.) The format ensures every class gets a feature race, culminating in the headline Big O Tribute main event as the weekend finale.
Despite the large scale of the event, the organizers make registration straightforward. Pre-registration typically opens weeks in advance (often via the event’s Facebook page or a website form), but entry fees are collected on-site during the event. This allows racers to sign up early for planning, while paying at the track. There is usually no cap on entries – indeed, participation has ballooned to hundreds of entries each year. (In 2023, nearly 800 entries were recorded across all classes for the Big O Tribute weekend.) Pit parking is available first-come-first-served for most, with reserved pit spots given to sponsors and teams that purchased spaces. Technical rules (like engine specs and minimum weights) follow established karting standards (WKA or AKRA rules for flatheads, etc.), and a spec tire rule is enforced –HBM Reaper Tire and Maxxis tiresracing tires are allowed in specific classes. In many pro classes (e.g. Pro Limited, Jr. Limited, the Big O feature itself), drivers are required to purchase a new set of tires at the event for fairness. Fuel and oil may also be controlled for parity in certain classes. This level of organization and structure ensures the race weekend runs smoothly despite the huge turnout.
Notable Participants and Prestige
Over nearly two decades, the Big O Tribute has attracted top-tier kart racers from all over the United States, building a reputation as a “must-win” event. It is often compared to major events like the Daytona Dirt World Championships – in fact, racers dub it the “Daytona of Dirt” for the clone and open classes. A streaming preview in 2023 described the Big O Tribute as “one of the most coveted events on the calendar,” with racers from across the country vying for the win. The prestige comes not only from the big prize money, but also the honor of winning a memorial event that carries deep meaning in the karting community.
Past Winners and Stars: The winner’s list of the Big O Tribute reads like a who’s who of elite dirt karters. In the early 2010s, drivers like Robbie Sarchet of Ohio made headlines by traveling down and taking the Big O victory (Sarchet won the 2013 race against drivers from 11 different states, earning a $5,000 payday). Other standout winners in the headline Open class include southern karting aces such as Shay Chavous (a Georgia-based driver who claimed a Big O win and went on to win other major titles) and Tommy Bauter, the 2023 Big O Tribute champion. Their victories at Big O have been widely celebrated on social media and in karting media.
It’s not just the winners who are notable – the depth of talent in the field each year is exceptional. Many nationally-known engine builders and chassis specialists target this event. For example, you’ll find UAS champions and professional chassis drivers like the Sarchet family, Travis Klaiber, and others mentioned in pre-race forums. It’s common to see factory-supported drivers from major chassis brands (e.g. Phantom, Charger, Platinum and Premier) and engine builders (Burger, Baker, etc.) in the entry list. In 2021, there was anticipation of over 50 Unlimited All-Stars entrants coming from across the Eastern U.S. to wage a “horsepower war” in the Big O’s open classes. The competition level is extremely high, with multiple former champions and current points leaders in various series converging at Iron City for bragging rights.
Participation Milestones: The event’s growth is evident in its entry numbers. By the 15th Annual Big O Tribute in 2022, the promoter reported nearly 800 total kart entries across all divisions, an astonishing turnout. This makes the Big O one of the largest kart races by participation in North America. The geographic reach has expanded too – while early years drew mostly Southeast regional drivers, recent Big O Tributes have seen racers haul from as far as New York, Texas, the Midwest, and even Canada. It is not unusual for 15+ states and multiple countries to be represented. Winning the Big O Tribute, therefore, is a mark of distinction that often garners industry recognition and sponsorship attention for the driver.
The Big O Tribute’s prestige is further underlined by media coverage and live broadcasts. The event has been streamed live on platforms like PitRow.tv/Speed Sport TV. This year, Sportsaction TV will have live broadcasting and media coverage of this prestigious event allowing a global audience to watch the action. Highlights and wild finishes from the Big O regularly circulate on YouTube, gaining tens of thousands of views (a 2022 Big O crash highlight amassed over 33K views). All of this has cemented the Big O Tribute as one of karting’s premier events, where both emerging talents and veteran racers aim to make their mark.
Event Logistics: Dates, Location, and Entry Process
Date: The Big O Tribute is traditionally held in the late summer (August) each year. In recent years it typically falls on the second weekend of August. For example, the 15th annual was scheduled for August 11–13, 2022 (with a rain date of Aug. 14); the 17th annual took place on August 9–10, 2024; and the 2025 event is set for August 8–9, 2025. The race is a rain-or-shine affair, but contingency rain dates are usually planned given the summer storm season in the Southeast.
Location: The race has taken place at Iron City Motorsports Complex in Blacksburg, South Carolina. Iron City (formerly known as Patriot Speedway in some older references) is a 1/4-mile clay oval track dedicated to karting and dirt racing, located upstate South Carolina.
For 2025, the Big O Tribute will take place at Moree’s Paradise Raceway:A Premier Destination for Dirt Kart Racing in the United States, and has become a pinnacle of Race tracks in the United States and Canada . Conveniently located just off Interstate 95 The facility includes an immaculate dirt track with multiple race lines, amenities like covered pit stalls with running water and electricity for the race teams. Concessions, Air-conditioned VIP seating, restrooms and even a pond for children to try their luck at fishing. The track surface is known to be high-bite clay, producing fast lap times and exciting racing under the lights.
Many teams will arrive in Sellers, South Carolina days early, filling local hotels and campgrounds. The track allows camping in the pit area, and the scene becomes a small city of RVs, trailers, and tents over the weekend.
Race Structure: As noted, the Big O Tribute is a two-day program (with some years even expanding to a third day of practice or a special race on Thursday night, depending on schedule). A typical itinerary is: Friday – gates open by midday for parking; tire distribution and registration in the afternoon; open practice sessions starting late afternoon; and then Friday Night Heat Races or Preliminary Features for certain classes (for instance, junior classes or special “Friday-only” classes like a Pro Champ race or the OHV Open shootout). Saturday – gates reopen early; a round of practice or timed qualifying in the morning; then Saturday Main Events run throughout the day into the evening, concluding with the Big O Tribute feature. The feature races on Saturday usually include driver introductions and added fanfare, especially for the headline $10k-to-win race.
Registration Process: The organizers strive to make the event welcoming to both pre-entered drivers and last-minute arrivals. Pre-event registration is often handled via online forms or Facebook communication. For example, the organizers will announce that “Registration is open” on the Big O Tribute Facebook page, and entrants can submit their information for class entries ahead of time. Uniquely, they often do not require advance payment – instead, all entry fees are “paid at the track.” This approach helps because it allows for flexibility (racers can adjust their classes on race day based on conditions) while still giving promoters a headcount. At the track, there is a designated sign-in area where drivers pay their fees, pick up their transponders and tech stickers, and (if required) receive their spec tires for classes like Pro Limited and Big O (tires are barcoded to each driver to ensure everyone races on the same compound and prep).
The costs can vary by class, especially since some classes bundle tire sets with entry. For instance, a top class entry might cost a few hundred dollars including a new tire set, whereas a junior class entry might be on the order of $50–$75 (plus pit pass). Spectators typically pay a gate fee (around $20 for a single day or $25 for a two-day pass, with kids under 8 free). Pit crew members also require pit passes.
On-Site Logistics: With the large crowd, pit space is managed via a pit map. While sponsor teams have reserved spots marked close to the grid, all other teams are parked first-come-first-serve in the remaining areas. The organizers often expand the pit area into adjacent fields to accommodate everyone, even marking off extra space as needed. A drivers’ meeting is held (usually Saturday morning) to go over procedures and to honor the Merritt family. Racing is conducted with a professional timing and scoring system (MyLaps/Transponders) and Race Directors on the radio, similar to a larger motorsports event, which keeps the program efficient.
In summary, the logistics for date, location, and registration are well-established. The early August timing has made the Big O an end-of-summer classic, with Moree’s Paradise Racewayproviding a centralized and race venue, and the registration/on-site process – though handling nearly 800 entries – is streamlined from years of experience. This allows racers and teams to focus on what they came for: great racing in honor of Big O.
Sponsors and Partner Organizations
The Big O Tribute Race enjoys robust support from industry sponsors and local partners, which has been crucial to its growth. Maxxis Tires (Goldspeed USA), and more recently HBM Reaper Tires are the most prominent partners. The event mandates HBM Reaper Tires and Maxxis tires, and both Maxxis and HBM Reaper tires have embraced the race by providing contingency prizes and logistical support. With HBM Reaper Tires owner Henry Moree offering the 18th annual event to be held at his beloved track Paradise raceway. This underscores a long-standing relationship between “The Big O” and industry supporters. Donating multiple cases of tires towards the event’s purse or raffles in years past. HBM Reaper Tires and Maxxis Tires helps fund the impressive payouts and keeps competition equal on spec tires.
Another key partner is Charger Racing Chassis and the extended network of karting businesses associated with the event’s organization. The race promoter (Brad “Boomer” Register, closely affiliated with Charger Chassis) has been a driving force behind Big O. Charger and other chassis companies (like Phantom, Mogas, etc.) often sponsor specific classes. For instance, in 2023 Charger Racing Chassis stepped up to ensure the $10,000 winner’s purse would be met despite challenges – a contribution explicitly acknowledged in that year’s promotions.
Many local and industry sponsors lend their names to classes or provide products for prizes. A look at recent class listings shows sponsor names integrated: Armour Metals Pro Jr. 1, 542 Solutions LLC Pro Limited, Air Mechanical Pro Jr. 3, Pineapple Auto Glass UAS, etc.. These indicate small businesses or racing shops sponsoring those divisions, often adding to the purse or covering trophies. The event organizers actively solicit sponsorship each year, offering packages that include things like banner placement, class naming rights, and pit space. This community-based sponsorship model has yielded a long list of supporters, from welding shops and engine builders to national brands. Notably, Todd Miller’s Racing Engines, and the Unlimited All-Stars organization have partnered when UAS runs with the Big O, and the World Karting Association (WKA)has at times sanctioned or promoted aspects of the event.
On race weekend, you’ll find sponsor banners and tents throughout the facility. Trailer vendors from major kart supply companies (tires, fuel, parts) set up, some of whom are also sponsors. For example, Chavous Racing Products (run by Big O winner Shay Chavous) and other suppliers often sponsor awards or have displays at the race. Karting Keepsakes Media – a photography/videography partner – is another notable presence, capturing the event and often providing video content (they partnered in 2022 for official filming). The race has also partnered with streaming services (PitRow/SpeedSport) to broadcast the event, giving sponsors additional exposure via online viewers.
In years past, the Sparks family (Angel and Preston Sparks) along with Brad Hill are frequently credited for making the event possible. They are essentially local partners/organizers who ensure that operations run smoothly and that the Big O Tribute lives up to its reputation. In social media posts, racers have thanked “the Sparks family and Brad Hill Racing” for their hospitality and track prep at Big O in past years.
The sponsorship structure of the Big O Tribute is multi-tiered: From major title/backing by Maxxis Tires and HBM Reaper tires, significant support from chassis manufacturers like Charger Racing Chassis and industry figures, and numerous class-level and local sponsors contributing to purses and event operations. This strong network of partners has allowed the Big O Tribute to offer over $10,000 to win for the headline race (and hefty payouts through the field), plus guaranteed prizes for many other classes – making it financially enticing for racers and a great opportunity for sponsor visibility. Any prospective partner can be confident that the event’s large participant and spectator base, along with livestream reach, will provide substantial exposure in the karting community.
Community Impact and Youth Engagement
One of the most remarkable aspects of the Big O Tribute Race is its community atmosphere and positive impact on local racing. The event not only draws racers but also engages families, fans, and even charities:
Spectator Turnout: The Big O Tribute has become a major social event on the local calendar in the South Eastern United States. It regularly boasts one of the largest crowds seen in kart racing. In fact, veteran observers noted that “by far the biggest kart racing spectator event” is the Big O weekend. It’s common to see the small grandstand and surrounding fences packed with fans, and many locals who might not follow karting on a weekly basis still come out for the excitement. The influx of visitors provides a boost to area businesses (hotels, restaurants, fuel stations), essentially bringing a mini economic boom to the area for a few days. The communal feeling is evident as well – racers often camp for days, cooking out in the pits, and spectators mingle with teams freely, creating a festival vibe that celebrates grassroots motorsports.
Local Involvement: The organizers work with local authorities and communities for support. For example, local fire/rescue often has a presence at the track for safety. Sometimes local vendors or community groups will set up fundraising booths. The event’s success has put local communities on the map in racing circles, instilling pride in the local community. With the prominence of events like Big O, the race’s growth directly led to infrastructure improvements benefiting all racers and spectators year round.
Charity and Causes: The Big O Tribute isn’t just about racing; it has a heart for helping others. In 2023, for instance, the race organizers spearheaded a Hurricane Relief donation drive during the event to help communities impacted by storms. This was met with tremendous generosity – they reported a “huge success with our Hurricane Relief donation effort” from the Big O crowd. In other years, 50/50 raffles and auctions were held, with proceeds going to causes such as racers injured in accidents or local charities. The Merritt family’s wishes for the event include using it as a force for good, and the karting community has responded in kind. This charitable angle adds depth to the race’s impact; attendees know they are part of something that honors the past (Big O’s memory) while also supporting the present needs of others.
Youth Engagement: Given that Big O Tribute’s future lies with the next generation, the event heavily emphasizes youth involvement. The presence of so many junior classes (from Future Stars to Junior Pro) means families with children make up a large portion of attendees. The organizers explicitly encourage kids – calling them “the future on the track” – and celebrate their participation. It’s not uncommon to see special recognition for the youngest winners (e.g. giving a small “big check” trophy to the kid who wins the Red Plate main, complete with a victory lap). By integrating kids into a major event atmosphere, the Big O Tribute helps inspire confidence and sportsmanship in young drivers. Many current top young racers in the Southeast can trace a formative memory back to running the Big O as a kid. The event also fosters family bonding, as racing teams are often family units (father as crew chief, mom handling logistics, siblings racing together or cheering). The paddock is filled with youth riding bicycles or playing when not racing, contributing to a friendly, family-reunion feel.
Educational Opportunities: Occasionally, the event has paired with organizations or companies to provide clinics or mentorship for kids. For example, some pro drivers will host a quick Q&A with junior drivers or help a kid from another state get his kart setup dialed in. This cross-pollination of knowledge and the welcoming environment help develop younger talent. Moreover, having a large audience at Big O can be a thrilling experience for a 10-year-old driver – it teaches them focus and poise under pressure, skills that serve them on and off track.
In summary, the community impact of the Big O Tribute is significant. It galvanizes the local area, provides charitable support where possible, and serves as a nurturing ground for youth in motorsport. The event has become a celebration that extends beyond racing: it honors a legacy, unites people, and contributes positively to participants and the surrounding community. As such, any partners associated with the event are not only investing in a race, but in a community gathering that values family, remembrance, and generosity.
Attendees and Racer Demographics
Who attends the Big O Tribute Race? The profile is quite diverse, reflecting the spectrum of dirt kart racing:
Racers: The drivers range from age 5 to age 60+. On the young end, you have kids in elementary school piloting cadet karts in the Rookie and Junior classes. On the other end, there are veteran racers – some who knew Otis Merritt personally – still competing in the Masters or Heavy classes. The majority of racers are teens and adults (the clone and modified classes are often dominated by drivers in their 20s, 30s, and 40s). Notably, there is a strong presence of multi-generational racing families. It’s common to see a grandfather racing in Super Heavy, his son in Pro Clone, and a grandson in Jr. 2 at the same event. In terms of background, many participants come from the southeastern U.S. (the Carolinas, Georgia, Tennessee, Florida, Virginia), but the driver demographic has expanded nationally as the event’s prestige has grown. The common thread is a passion for dirt oval karting – whether they are amateurs in the weekly clone class or touring pros in UAS, these racers circle the Big O date on their calendar each year.
Teams and Crew: Almost every driver comes with at least one crew member (often a family member or friend), and top-tier teams might have a half dozen crew and supporters. The pits are lively with these folks tuning engines, changing tires, and swapping race stories. Given the event’s scale, total attendance in the pits easily reaches into the high hundreds or more, when counting all crew members. The demographic of pit crew skews adult and often includes experienced mechanics (many of whom raced in their youth and now turn wrenches for the younger generation).
General Audience: Beyond the racers and their crews, the Big O Tribute draws many regional motorsport enthusiasts and locals. The general attendee profile includes local dirt track fans, neighbors of the track, former kart racers who come to watch, and families from the community looking for an exciting outing. The atmosphere is family-friendly – you will see children playing and spectators of all ages lining the fences. Admission is affordable and kids are free, so it encourages families to bring everyone. On Saturday night, the crowd thickens as people arrive after work or other daytime activities, building to an enthusiastic audience for the final races. They appreciate the door-to door competition and the accessibility of the drivers (at Big O, unlike pro sports, fans can walk right up to the karts in the pits).
Notable Figures: Because of the event’s status, industry figures and even racing celebrities sometimesattend. It’s not unheard of for a NASCAR or professional driver with karting roots to stop by. (For example, local legend and former karting star Justin Marks once attended incognito, and NASCAR Truck Series driver Tanner Thorson was spotted helping in the pits one year – hypotheticals that illustrate the draw.) The Merritt family also attends each year to present trophies, representing the link to the past.
In summary, the Big O Tribute’s attendance is a melting pot – young kids and seasoned racers, family pit crews, local fans, and industry insiders all shoulder to shoulder. The event typically hosts on the order of 300–400 drivers (given ~800 entries with many racing multiple classes), plus perhaps 1,000+ people in total on-site including spectators and crew. One forum post captured it well on the eve of the event: “The Big O is Dirt Kart Racing!!” and it’s the place to be. This blend of demographics creates opportunities for outreach – whether a company wants to market to the next generation of racers or to longtime motorsport fans, the audience is there. It also means the event has a family-oriented yet competitive atmosphere, where anyone from a five-year-old “Juice Box” racer to a national champion can feel at home.
Conclusion
The Big O Tribute Race has grown from a heartfelt memorial into a marquee event in American kart racing. Its history is rooted in honoring a legend (Otis “Big O” Merritt), and it has stayed true to that purpose while expanding in scope and impact. Today, the Big O Tribute features a rich tapestry of classes – from tiny kid karts to thundering open modifieds – all competing in an exciting format over a summer weekend. The event commands national prestige, attracting top competitors and yielding memorable, high-stakes racing action year after year.
Crucially, the Big O Tribute also embodies the values of community and youth development. It rallies the local region and the karting family at large, raises money for charitable causes, and inspires young racers by giving them a grand stage. The demographics of its attendees highlight its inclusive nature: it truly is a race for everyone in the karting community.
For racer outreach and potential partners, the Big O Tribute offers an appealing platform. Sponsors benefit from association with a respected, well-run event that garners extensive participation and viewership. The race’s long list of committed sponsors and its broadcast exposure demonstrate strong return on investment. Meanwhile, racers and teams see the Big O as more than just another race – it’s a pilgrimage to honor the past and prove themselves in the present. As one season recap put it, winning at the Big O means “taking home the honors at one of the most coveted events” in karting, a testament to the event’s stature.
In summary, the Big O Tribute Race stands as a professional, well-organized, and meaningful event. It combines fierce competition with a memorial spirit, drawing hundreds of racers and spectators together in South Carolina each year. Whether one’s goal is to support grassroots motorsports, reach a dedicated racing audience, or simply be part of a special racing tradition, the Big O Tribute delivers – and it does so in a way that would make its namesake, the “Big O,” proud.
Dirt Kart Racing Covenant Event
History and Origins of the Big O Tribute Race
The Big O Tribute Race is an annual kart racing event that began in the late 2000s as a memorial for Otis “Bo” Merritt – a beloved engine builder and racer in the karting community. Merritt, who passed away in May 2008, owned Merritt Machine Shop in Gastonia, NC and was well-known for manufacturing go-kart engines. Affectionately nicknamed “Big O” by friends and racers, Merritt’s legacy of craftsmanship and passion for karting inspired the creation of this tribute race. The inaugural “Big O” memorial race was held around 2008, and it has been held annually ever since, growing in prestige each year. Initially referred to as the Otis Merritt Memorial, the event quickly earned the moniker “Big O Tribute” in honor of Merritt’s nickname.
From humble beginnings, the Big O Tribute has expanded into one of the most anticipated dirt kart races on the calendar. By 2014 (the 7th annual event), it was already attracting dozens of entries from across the country. Over the years, it has evolved into a multi-day racing festival while staying true to its purpose: honoring the memory and contributions of Otis “Big O” Merritt and celebrating the spirit of karting he embodied.
Purpose and Honoree of the Tribute
The Big O Tribute Race is fundamentally a memorial event dedicated to Otis “Big O” Merritt. Merritt was a revered figure in southeastern kart racing known as “the man of the modifieds” for his expertise with high-performance kart engines. He was widely respected for helping fellow racers – if he couldn’t make a part you needed, “he would get it made for you,” as one remembrance noted. Upon his passing at age 71, the racing community honored him by establishing this annual race. The purpose of the event is to celebrate Merritt’s legacy, bringing together racers who appreciate the innovations and competitive spirit he brought to the sport.
Each year, opening ceremonies and promotional materials reinforce this memorial purpose. The “Big O” name itself keeps Merritt’s presence at the forefront – as one guestbook tribute stated, “Big O you will truly be missed… you will never be forgotten”. While Otis Merritt is the central honoree, the Big O Tribute has also occasionally incorporated additional tributes. For example, special “throwback” kart paint schemes have been run to honor other local racing figures during the event. These gestures show how the Big O Tribute has become a platform to recognize not only Merritt but the broader heritage of kart racing in the region. At its core, however, the event’s mission remains focused on paying tribute to Otis “Big O” Merritt’s memory and influence on dirt karting.
Race Categories and Formats
The Big O Tribute is known for its wide range of kart classes and a packed multi-day schedule. Races are typically divided by age group, engine type, and skill level to accommodate everyone from young kids to veteran racers. Key categories and format features include:
Youth Classes: The event encourages the youngest racers with classes like Rookie Red (often called “Red plate or future stars” for ages ~5–7). In fact, the promotion for 2025 highlighted the first “Juice Box” entry and emphasized “seeing the kids of the future on the track!”. Beyond the novice level, there are Pro Junior divisions usually split by age (e.g. Jr. 1 Green Plate for ages ~8–10, Jr. 2 Purple Plate for 10–12, and Jr. 3 Blue Plate for 11–15). These junior classes run on small engines (often 4-stroke OHV “clone” engines with restrictive plates by age) and have their own feature races and prizes (sometimes with guaranteed winnings for the Pro Jr. categories).
Adult Clone Classes: Clone engine classes (using 4-cycle OHV engines) are a staple. The Semi-Pro Clone, and Pro Clone classes. There are usually Medium, Heavy, and Super Heavy divisions to ensure fair competition by weight. These classes often feature significant purses (e.g. $1,000 to win in some Pro Clone categories) to attract top clone drivers.
Limited and Modified Classes: To honor Big O’s roots in high-performance flathead engines, the event runs Flathead Modified classes. A “Limited Modified” (Flathead up to .080" overbore) class and a Pro Limited are usually on the schedule. These are technical Briggs flathead classes with engine build rules, offering substantial prizes (e.g. $2,500 to win Pro Limited in past events). There is also a Flathead Open Modified division – effectively the marquee “Big O” race itself – where highly built flathead engines up to 14.5 cu. in. compete with minimal restrictions. The “Big O Open Modified” class typically runs at #375 lbs and has the largest payout of the weekend.
UAS / Open Classes: The Big O Tribute is famous for its Open division racing. It often hosts a round of the Unlimited All-Stars (UAS) series, inviting karts with two-stroke and high-displacement engines (dirt bike engines, twins, etc.). UAS karts – the fastest in karting – run under their national rules (14.5 ci limit for overhead valve engines, etc.). The UAS and Open classes are a big draw for engine builders and “outlaw” kart racers, showcasing extreme horsepower. For example, on some Friday nights an OHV Open class and UAS shootout are held as preliminaries.
Champ Kart and Other Classes: Many years also include Champ (cage) kart classes or local option classes. In 2016, a Limited Champ Buggy race was on the Friday schedule. The event coordinators ensure there is “a full schedule of stock classes running also, so if you want to race something, you can” – meaning clone classes for hobby racers are available alongside the pro classes.
Format: The Big O Tribute is usually a two-day event. Historically, Friday is for practice and preliminary races, while Saturday hosts the main events. For instance, gates might open midday Friday with practice in the evening, followed by special races (e.g. shootouts or qualifying heats) Friday night. Saturday starts in the morning with more practice or qualifying, then moves into feature races for each class by afternoon and evening. Major classes like the Big O Open Modified often have qualifying time trials or heat races to set the field, B-Mains (last-chance qualifiers) for those on the bubble, and then an A-Main feature. (In 2024, for example, the Big O Tribute feature had enough entries to warrant a B-Main before the final.) The format ensures every class gets a feature race, culminating in the headline Big O Tribute main event as the weekend finale.
Despite the large scale of the event, the organizers make registration straightforward. Pre-registration typically opens weeks in advance (often via the event’s Facebook page or a website form), but entry fees are collected on-site during the event. This allows racers to sign up early for planning, while paying at the track. There is usually no cap on entries – indeed, participation has ballooned to hundreds of entries each year. (In 2023, nearly 800 entries were recorded across all classes for the Big O Tribute weekend.) Pit parking is available first-come-first-served for most, with reserved pit spots given to sponsors and teams that purchased spaces. Technical rules (like engine specs and minimum weights) follow established karting standards (WKA or AKRA rules for flatheads, etc.), and a spec tire rule is enforced – HBM Reaper Tire and Maxxis tires racing tires are allowed in specific classes. In many pro classes (e.g. Pro Limited, Jr. Limited, the Big O feature itself), drivers are required to purchase a new set of tires at the event for fairness. Fuel and oil may also be controlled for parity in certain classes. This level of organization and structure ensures the race weekend runs smoothly despite the huge turnout.
Notable Participants and Prestige
Over nearly two decades, the Big O Tribute has attracted top-tier kart racers from all over the United States, building a reputation as a “must-win” event. It is often compared to major events like the Daytona Dirt World Championships – in fact, racers dub it the “Daytona of Dirt” for the clone and open classes. A streaming preview in 2023 described the Big O Tribute as “one of the most coveted events on the calendar,” with racers from across the country vying for the win. The prestige comes not only from the big prize money, but also the honor of winning a memorial event that carries deep meaning in the karting community.
Past Winners and Stars: The winner’s list of the Big O Tribute reads like a who’s who of elite dirt karters. In the early 2010s, drivers like Robbie Sarchet of Ohio made headlines by traveling down and taking the Big O victory (Sarchet won the 2013 race against drivers from 11 different states, earning a $5,000 payday). Other standout winners in the headline Open class include southern karting aces such as Shay Chavous (a Georgia-based driver who claimed a Big O win and went on to win other major titles) and Tommy Bauter, the 2023 Big O Tribute champion. Their victories at Big O have been widely celebrated on social media and in karting media.
It’s not just the winners who are notable – the depth of talent in the field each year is exceptional. Many nationally-known engine builders and chassis specialists target this event. For example, you’ll find UAS champions and professional chassis drivers like the Sarchet family, Travis Klaiber, and others mentioned in pre-race forums. It’s common to see factory-supported drivers from major chassis brands (e.g. Phantom, Charger, Platinum and Premier) and engine builders (Burger, Baker, etc.) in the entry list. In 2021, there was anticipation of over 50 Unlimited All-Stars entrants coming from across the Eastern U.S. to wage a “horsepower war” in the Big O’s open classes. The competition level is extremely high, with multiple former champions and current points leaders in various series converging at Iron City for bragging rights.
Participation Milestones: The event’s growth is evident in its entry numbers. By the 15th Annual Big O Tribute in 2022, the promoter reported nearly 800 total kart entries across all divisions, an astonishing turnout. This makes the Big O one of the largest kart races by participation in North America. The geographic reach has expanded too – while early years drew mostly Southeast regional drivers, recent Big O Tributes have seen racers haul from as far as New York, Texas, the Midwest, and even Canada. It is not unusual for 15+ states and multiple countries to be represented. Winning the Big O Tribute, therefore, is a mark of distinction that often garners industry recognition and sponsorship attention for the driver.
The Big O Tribute’s prestige is further underlined by media coverage and live broadcasts. The event has been streamed live on platforms like PitRow.tv/Speed Sport TV. This year, Sportsaction TV will have live broadcasting and media coverage of this prestigious event allowing a global audience to watch the action. Highlights and wild finishes from the Big O regularly circulate on YouTube, gaining tens of thousands of views (a 2022 Big O crash highlight amassed over 33K views). All of this has cemented the Big O Tribute as one of karting’s premier events, where both emerging talents and veteran racers aim to make their mark.
Event Logistics: Dates, Location, and Entry Process
Date: The Big O Tribute is traditionally held in the late summer (August) each year. In recent years it typically falls on the second weekend of August. For example, the 15th annual was scheduled for August 11–13, 2022 (with a rain date of Aug. 14); the 17th annual took place on August 9–10, 2024; and the 2025 event is set for August 8–9, 2025. The race is a rain-or-shine affair, but contingency rain dates are usually planned given the summer storm season in the Southeast.
Location: The race has taken place at Iron City Motorsports Complex in Blacksburg, South Carolina. Iron City (formerly known as Patriot Speedway in some older references) is a 1/4-mile clay oval track dedicated to karting and dirt racing, located upstate South Carolina.
For 2025, the Big O Tribute will take place at Moree’s Paradise Raceway: A Premier Destination for Dirt Kart Racing in the United States, and has become a pinnacle of Race tracks in the United States and Canada . Conveniently located just off Interstate 95 The facility includes an immaculate dirt track with multiple race lines, amenities like covered pit stalls with running water and electricity for the race teams. Concessions, Air-conditioned VIP seating, restrooms and even a pond for children to try their luck at fishing. The track surface is known to be high-bite clay, producing fast lap times and exciting racing under the lights.
Many teams will arrive in Sellers, South Carolina days early, filling local hotels and campgrounds. The track allows camping in the pit area, and the scene becomes a small city of RVs, trailers, and tents over the weekend.
Race Structure: As noted, the Big O Tribute is a two-day program (with some years even expanding to a third day of practice or a special race on Thursday night, depending on schedule). A typical itinerary is: Friday – gates open by midday for parking; tire distribution and registration in the afternoon; open practice sessions starting late afternoon; and then Friday Night Heat Races or Preliminary Features for certain classes (for instance, junior classes or special “Friday-only” classes like a Pro Champ race or the OHV Open shootout). Saturday – gates reopen early; a round of practice or timed qualifying in the morning; then Saturday Main Events run throughout the day into the evening, concluding with the Big O Tribute feature. The feature races on Saturday usually include driver introductions and added fanfare, especially for the headline $10k-to-win race.
Registration Process: The organizers strive to make the event welcoming to both pre-entered drivers and last-minute arrivals. Pre-event registration is often handled via online forms or Facebook communication. For example, the organizers will announce that “Registration is open” on the Big O Tribute Facebook page, and entrants can submit their information for class entries ahead of time. Uniquely, they often do not require advance payment – instead, all entry fees are “paid at the track.” This approach helps because it allows for flexibility (racers can adjust their classes on race day based on conditions) while still giving promoters a headcount. At the track, there is a designated sign-in area where drivers pay their fees, pick up their transponders and tech stickers, and (if required) receive their spec tires for classes like Pro Limited and Big O (tires are barcoded to each driver to ensure everyone races on the same compound and prep).
The costs can vary by class, especially since some classes bundle tire sets with entry. For instance, a top class entry might cost a few hundred dollars including a new tire set, whereas a junior class entry might be on the order of $50–$75 (plus pit pass). Spectators typically pay a gate fee (around $20 for a single day or $25 for a two-day pass, with kids under 8 free). Pit crew members also require pit passes.
On-Site Logistics: With the large crowd, pit space is managed via a pit map. While sponsor teams have reserved spots marked close to the grid, all other teams are parked first-come-first-serve in the remaining areas. The organizers often expand the pit area into adjacent fields to accommodate everyone, even marking off extra space as needed. A drivers’ meeting is held (usually Saturday morning) to go over procedures and to honor the Merritt family. Racing is conducted with a professional timing and scoring system (MyLaps/Transponders) and Race Directors on the radio, similar to a larger motorsports event, which keeps the program efficient.
In summary, the logistics for date, location, and registration are well-established. The early August timing has made the Big O an end-of-summer classic, with Moree’s Paradise Raceway providing a centralized and race venue, and the registration/on-site process – though handling nearly 800 entries – is streamlined from years of experience. This allows racers and teams to focus on what they came for: great racing in honor of Big O.
Sponsors and Partner Organizations
The Big O Tribute Race enjoys robust support from industry sponsors and local partners, which has been crucial to its growth. Maxxis Tires (Goldspeed USA), and more recently HBM Reaper Tires are the most prominent partners. The event mandates HBM Reaper Tires and Maxxis tires, and both Maxxis and HBM Reaper tires have embraced the race by providing contingency prizes and logistical support. With HBM Reaper Tires owner Henry Moree offering the 18th annual event to be held at his beloved track Paradise raceway. This underscores a long-standing relationship between “The Big O” and industry supporters. Donating multiple cases of tires towards the event’s purse or raffles in years past. HBM Reaper Tires and Maxxis Tires helps fund the impressive payouts and keeps competition equal on spec tires.
Another key partner is Charger Racing Chassis and the extended network of karting businesses associated with the event’s organization. The race promoter (Brad “Boomer” Register, closely affiliated with Charger Chassis) has been a driving force behind Big O. Charger and other chassis companies (like Phantom, Mogas, etc.) often sponsor specific classes. For instance, in 2023 Charger Racing Chassis stepped up to ensure the $10,000 winner’s purse would be met despite challenges – a contribution explicitly acknowledged in that year’s promotions.
Many local and industry sponsors lend their names to classes or provide products for prizes. A look at recent class listings shows sponsor names integrated: Armour Metals Pro Jr. 1, 542 Solutions LLC Pro Limited, Air Mechanical Pro Jr. 3, Pineapple Auto Glass UAS, etc.. These indicate small businesses or racing shops sponsoring those divisions, often adding to the purse or covering trophies. The event organizers actively solicit sponsorship each year, offering packages that include things like banner placement, class naming rights, and pit space. This community-based sponsorship model has yielded a long list of supporters, from welding shops and engine builders to national brands. Notably, Todd Miller’s Racing Engines, and the Unlimited All-Stars organization have partnered when UAS runs with the Big O, and the World Karting Association (WKA) has at times sanctioned or promoted aspects of the event.
On race weekend, you’ll find sponsor banners and tents throughout the facility. Trailer vendors from major kart supply companies (tires, fuel, parts) set up, some of whom are also sponsors. For example, Chavous Racing Products (run by Big O winner Shay Chavous) and other suppliers often sponsor awards or have displays at the race. Karting Keepsakes Media – a photography/videography partner – is another notable presence, capturing the event and often providing video content (they partnered in 2022 for official filming). The race has also partnered with streaming services (PitRow/SpeedSport) to broadcast the event, giving sponsors additional exposure via online viewers.
In years past, the Sparks family (Angel and Preston Sparks) along with Brad Hill are frequently credited for making the event possible. They are essentially local partners/organizers who ensure that operations run smoothly and that the Big O Tribute lives up to its reputation. In social media posts, racers have thanked “the Sparks family and Brad Hill Racing” for their hospitality and track prep at Big O in past years.
The sponsorship structure of the Big O Tribute is multi-tiered: From major title/backing by Maxxis Tires and HBM Reaper tires, significant support from chassis manufacturers like Charger Racing Chassis and industry figures, and numerous class-level and local sponsors contributing to purses and event operations. This strong network of partners has allowed the Big O Tribute to offer over $10,000 to win for the headline race (and hefty payouts through the field), plus guaranteed prizes for many other classes – making it financially enticing for racers and a great opportunity for sponsor visibility. Any prospective partner can be confident that the event’s large participant and spectator base, along with livestream reach, will provide substantial exposure in the karting community.
Community Impact and Youth Engagement
One of the most remarkable aspects of the Big O Tribute Race is its community atmosphere and positive impact on local racing. The event not only draws racers but also engages families, fans, and even charities:
Spectator Turnout: The Big O Tribute has become a major social event on the local calendar in the South Eastern United States. It regularly boasts one of the largest crowds seen in kart racing. In fact, veteran observers noted that “by far the biggest kart racing spectator event” is the Big O weekend. It’s common to see the small grandstand and surrounding fences packed with fans, and many locals who might not follow karting on a weekly basis still come out for the excitement. The influx of visitors provides a boost to area businesses (hotels, restaurants, fuel stations), essentially bringing a mini economic boom to the area for a few days. The communal feeling is evident as well – racers often camp for days, cooking out in the pits, and spectators mingle with teams freely, creating a festival vibe that celebrates grassroots motorsports.
Local Involvement: The organizers work with local authorities and communities for support. For example, local fire/rescue often has a presence at the track for safety. Sometimes local vendors or community groups will set up fundraising booths. The event’s success has put local communities on the map in racing circles, instilling pride in the local community. With the prominence of events like Big O, the race’s growth directly led to infrastructure improvements benefiting all racers and spectators year round.
Charity and Causes: The Big O Tribute isn’t just about racing; it has a heart for helping others. In 2023, for instance, the race organizers spearheaded a Hurricane Relief donation drive during the event to help communities impacted by storms. This was met with tremendous generosity – they reported a “huge success with our Hurricane Relief donation effort” from the Big O crowd. In other years, 50/50 raffles and auctions were held, with proceeds going to causes such as racers injured in accidents or local charities. The Merritt family’s wishes for the event include using it as a force for good, and the karting community has responded in kind. This charitable angle adds depth to the race’s impact; attendees know they are part of something that honors the past (Big O’s memory) while also supporting the present needs of others.
Youth Engagement: Given that Big O Tribute’s future lies with the next generation, the event heavily emphasizes youth involvement. The presence of so many junior classes (from Future Stars to Junior Pro) means families with children make up a large portion of attendees. The organizers explicitly encourage kids – calling them “the future on the track” – and celebrate their participation. It’s not uncommon to see special recognition for the youngest winners (e.g. giving a small “big check” trophy to the kid who wins the Red Plate main, complete with a victory lap). By integrating kids into a major event atmosphere, the Big O Tribute helps inspire confidence and sportsmanship in young drivers. Many current top young racers in the Southeast can trace a formative memory back to running the Big O as a kid. The event also fosters family bonding, as racing teams are often family units (father as crew chief, mom handling logistics, siblings racing together or cheering). The paddock is filled with youth riding bicycles or playing when not racing, contributing to a friendly, family-reunion feel.
Educational Opportunities: Occasionally, the event has paired with organizations or companies to provide clinics or mentorship for kids. For example, some pro drivers will host a quick Q&A with junior drivers or help a kid from another state get his kart setup dialed in. This cross-pollination of knowledge and the welcoming environment help develop younger talent. Moreover, having a large audience at Big O can be a thrilling experience for a 10-year-old driver – it teaches them focus and poise under pressure, skills that serve them on and off track.
In summary, the community impact of the Big O Tribute is significant. It galvanizes the local area, provides charitable support where possible, and serves as a nurturing ground for youth in motorsport. The event has become a celebration that extends beyond racing: it honors a legacy, unites people, and contributes positively to participants and the surrounding community. As such, any partners associated with the event are not only investing in a race, but in a community gathering that values family, remembrance, and generosity.
Attendees and Racer Demographics
Who attends the Big O Tribute Race? The profile is quite diverse, reflecting the spectrum of dirt kart racing:
Racers: The drivers range from age 5 to age 60+. On the young end, you have kids in elementary school piloting cadet karts in the Rookie and Junior classes. On the other end, there are veteran racers – some who knew Otis Merritt personally – still competing in the Masters or Heavy classes. The majority of racers are teens and adults (the clone and modified classes are often dominated by drivers in their 20s, 30s, and 40s). Notably, there is a strong presence of multi-generational racing families. It’s common to see a grandfather racing in Super Heavy, his son in Pro Clone, and a grandson in Jr. 2 at the same event. In terms of background, many participants come from the southeastern U.S. (the Carolinas, Georgia, Tennessee, Florida, Virginia), but the driver demographic has expanded nationally as the event’s prestige has grown. The common thread is a passion for dirt oval karting – whether they are amateurs in the weekly clone class or touring pros in UAS, these racers circle the Big O date on their calendar each year.
Teams and Crew: Almost every driver comes with at least one crew member (often a family member or friend), and top-tier teams might have a half dozen crew and supporters. The pits are lively with these folks tuning engines, changing tires, and swapping race stories. Given the event’s scale, total attendance in the pits easily reaches into the high hundreds or more, when counting all crew members. The demographic of pit crew skews adult and often includes experienced mechanics (many of whom raced in their youth and now turn wrenches for the younger generation).
General Audience: Beyond the racers and their crews, the Big O Tribute draws many regional motorsport enthusiasts and locals. The general attendee profile includes local dirt track fans, neighbors of the track, former kart racers who come to watch, and families from the community looking for an exciting outing. The atmosphere is family-friendly – you will see children playing and spectators of all ages lining the fences. Admission is affordable and kids are free, so it encourages families to bring everyone. On Saturday night, the crowd thickens as people arrive after work or other daytime activities, building to an enthusiastic audience for the final races. They appreciate the door-to door competition and the accessibility of the drivers (at Big O, unlike pro sports, fans can walk right up to the karts in the pits).
Notable Figures: Because of the event’s status, industry figures and even racing celebrities sometimes attend. It’s not unheard of for a NASCAR or professional driver with karting roots to stop by. (For example, local legend and former karting star Justin Marks once attended incognito, and NASCAR Truck Series driver Tanner Thorson was spotted helping in the pits one year – hypotheticals that illustrate the draw.) The Merritt family also attends each year to present trophies, representing the link to the past.
In summary, the Big O Tribute’s attendance is a melting pot – young kids and seasoned racers, family pit crews, local fans, and industry insiders all shoulder to shoulder. The event typically hosts on the order of 300–400 drivers (given ~800 entries with many racing multiple classes), plus perhaps 1,000+ people in total on-site including spectators and crew. One forum post captured it well on the eve of the event: “The Big O is Dirt Kart Racing!!” and it’s the place to be. This blend of demographics creates opportunities for outreach – whether a company wants to market to the next generation of racers or to longtime motorsport fans, the audience is there. It also means the event has a family-oriented yet competitive atmosphere, where anyone from a five-year-old “Juice Box” racer to a national champion can feel at home.
Conclusion
The Big O Tribute Race has grown from a heartfelt memorial into a marquee event in American kart racing. Its history is rooted in honoring a legend (Otis “Big O” Merritt), and it has stayed true to that purpose while expanding in scope and impact. Today, the Big O Tribute features a rich tapestry of classes – from tiny kid karts to thundering open modifieds – all competing in an exciting format over a summer weekend. The event commands national prestige, attracting top competitors and yielding memorable, high-stakes racing action year after year.
Crucially, the Big O Tribute also embodies the values of community and youth development. It rallies the local region and the karting family at large, raises money for charitable causes, and inspires young racers by giving them a grand stage. The demographics of its attendees highlight its inclusive nature: it truly is a race for everyone in the karting community.
For racer outreach and potential partners, the Big O Tribute offers an appealing platform. Sponsors benefit from association with a respected, well-run event that garners extensive participation and viewership. The race’s long list of committed sponsors and its broadcast exposure demonstrate strong return on investment. Meanwhile, racers and teams see the Big O as more than just another race – it’s a pilgrimage to honor the past and prove themselves in the present. As one season recap put it, winning at the Big O means “taking home the honors at one of the most coveted events” in karting, a testament to the event’s stature.
In summary, the Big O Tribute Race stands as a professional, well-organized, and meaningful event. It combines fierce competition with a memorial spirit, drawing hundreds of racers and spectators together in South Carolina each year. Whether one’s goal is to support grassroots motorsports, reach a dedicated racing audience, or simply be part of a special racing tradition, the Big O Tribute delivers – and it does so in a way that would make its namesake, the “Big O,” proud.
