John Card sees a bright future for Sassy Engines.

Just over a year ago, Card moved the veteran builder of truck and tractor-pull engines from its longtime location in Concord, New Hampshire, to Brownsburg, Indiana, and into what he calls a “collaborative partnership” with Don Schumacher Racing (DSR) and its retail and manufacturing branches. Financially, Sassy Engines remains a separate entity, but sharing building space and engineering resources with DSR Performance and DSM Precision Manufacturing creates synergy and possibilities that didn’t exist in New England.

Already, DSR has released new forged Hemi connecting rods for tractor pulling, engineered with Card’s input. “And we’re working on cylinder heads and blocks,” Card added. “Right now, in alcohol drag racing, in monster trucks, and in alcohol-series tractor pulling, there are only three manufacturers who make the key components. Two of them are in California, one is in South Carolina, and they are all overwhelmed. They can’t keep up with what’s going on in the industry. By bringing my engineering experience and my tractor-pulling experience out here to DSR/DSM, we’re going to make another BAE [Brad Anderson Enterprises] or AJPE [Alan Johnson Performance Engineering] in the Midwest. If we build 10 more motors a year, that’s awesome, but I see the future in making our own products.”

Sassy Massey & The Country Girl

Listen to Card carefully, and you’ll hear traces of a New England accent—no surprise when you learn he was born in Rockville, Rhode Island. A self-described gearhead, he built a four-wheel-drive pulling truck while he was still in high school. After school, he pumped gas at his uncle’s Getty station in Hopkinton.

When he graduated, his uncle finessed him a job at Hoxsie Buick-Pontiac in Westerly. For the next seven years, Card worked his way up from floor sweeper to service manager, while earning a degree in automotive science from the GM Training Center in Dedham, Massachusetts. His truck-pulling career moved up from county fairs to the US Hot Rod Association’s indoor circuit.

Needing a change, he parked the truck in 2000 and quit the dealership business in 2003 to drive a log truck. Around 2006 he took a “side gig” with an Alcohol Funny Car team. They needed Hemi parts, and from his pulling days, Card knew a guy named Brian Knox.

Brian’s mother was Rodalyn Knox, who drove Funny Cars in the 1970s under the nom de guerre “Country Girl.” Only the fourth woman to receive an NHRA Funny Car license, Rodalyn set track records at the New England Dragway in Epping, New Hampshire, and at the Oxford Plains Dragway in Oxford, Maine.

Beginning in 1979, Rodalyn and husband John campaigned a series of ever-more-powerful pulling tractors helmed by a succession of hired drivers. Pulling was surging in popularity, and Brian was learning to build engines. Initially, the tractors were named “Sassy Massey”—presumably a reference to Massey Ferguson—but the family’s latest six-Hemi behemoth was rechristened “Country Girl” in 1990 as Rodalyn returned to the wheel. She clinched the NTPA Unlimited 7,600-pound Grand National Championship in 1995, 1997, and 1998 before retiring for the second and final time to manage a new Knox family enterprise initially called Sassy Racing Engines.

Eight years later, John Card walked through their door, seeking supplies for his Funny Car team. “So John [Knox] and me are BS’ing, and I said, ‘If you ever decide you’re going to retire, I’ll take your job’—laugh, joke. Two days later, John calls me up and asks when I can come in and talk.” By 2014, Card was president of Sassy Racing Engines. When Brian retired in 2019, Card bought the business.

Pulling Up Roots

Then COVID-19 hit. “It was tough,” Card recalled, but even the Pandemic wasn’t the toughest challenge he faced. “In the 1980s, 1990s, and early 2000s, there was a lot of money in pulling”—but not so much anymore. “You have to be versatile and do other things.”

Furthermore, Sassy’s New England location proved less than ideal. “If we needed a fitting on a hose, we had to call XRP in California. And if we were in the middle of a job and needed to get it done, we had to pay $100 to overnight a $12 fitting. We had to send our blocks to Brad Anderson in California and wait weeks or months to get them repaired. We had to send our cylinder heads to Noonan in South Carolina and wait weeks or months. Not that they were doing anything wrong—these are great companies and great people. They just have so much to do. We were getting bigger and bigger, and generating more work, and had no one to do it. That was slowing down cash flow tremendously.”

Kirk Dooley became director of INDY NXT by Firestone this past April, overseeing all operations and competition for INDYCAR’s developmental series. The series prepares drivers, engineers, and other team personnel for the flagship NTT INDYCAR SERIES.

For the Indiana native, taking the role was like coming home. Dooley had been INDYCAR chief of staff in 2015–2016 and then became director of event operations at Indianapolis Motor Speedway in 2016. He left INDYCAR in 2020 to become chief operating officer of the Skip Barber Racing School. There, in addition to helping expand business operations, he managed a four-car race team that won the 2021 SRO TC class championship and placed second in the TCA Class during the team’s inaugural season. Most recently, Dooley was the owner of Indianapolis-based Torque Lab, which provides engine management software and racing services to performance shops and race teams.

Dooley entered the motorsports industry after a 24-year career in the US Marine Corps, which he left as second-in-command of Marine Forces Special Operations Command. His passion for motor racing started long before his military career. As a young boy visiting his grandparents in Liberty, Indiana, Dooley could hear the dirt track racing nearby on Saturday nights.

“We finally attended a race, and I became gripped by the speed and noise,” he recalled for PRI. He later dove into the world of fast cars with a 1994 Ford Mustang Cobra into which he admitted investing “an embarrassing amount of money” to engage in drag racing, autocross, and road racing.

“That led to the same in motorcycles, then back to cars, and it continued to grow from there,” he added.

PRI: Your civilian career history is all racing. How did you get your start in this industry?

Dooley: When it came time to retire from the Marine Corps, I decided to make my new profession in the racing industry. I believe that there are a lot of very translatable skills between fast-paced and complex missions within special operations and the dynamic high stakes world of racing.

PRI: You have extensive experience with major racing organizations. Does anything about managing INDY NXT stand out as a particular challenge?

Dooley: One challenge and core goal is evolving INDY NXT by Firestone from a traditionally pay-to-play series into a more commercially sustainable championship, and to help teams and drivers be less reliant on their own budgets. This may take some time, but the potential is there. Interest from new teams and high-caliber drivers continues to grow. We have the integrated support of INDYCAR, strong partnerships in Firestone, and we’re on TV like never before. Fox Sports will show every INDY NXT race live on FS1 or FS2, and INDYCAR Live is rapidly growing in international markets, giving the series unprecedented exposure. We are bullish that the combination of circumstances will elevate the series in a way that will further attract top driver talent and stakeholders alike and help improve the economic models...

The show on race day is bright, fast, and loud. Racing has always been a sensory-rich sport, inundating fans with sounds that can be felt in the bones, colors that flash past in the blink of an eye, and the full gamut of human drama on display.

But the tools that bring that show to life are quieter, often operating unseen in the background. Take cloud computing, for example. Advances in internet bandwidth and speed, remote data storage, machine learning, and human interface with these systems have transformed the paddock. The days of race teams and sanctioning bodies constructing racks of servers at their headquarters to compile data are fading into the rearview mirror. The day of instant access to terabytes of data using remote servers has arrived.

SRO Motorsports Group, based in Austin, Texas, illustrates how thoroughly cloud computing has worked its way into all facets of motorsports. The sanction works closely with Amazon Web Services (AWS), series sponsor for GT World Challenge and GT America. “We use cloud computing across our entire business,” said Greg Gill. “It is how our business is organized and stored from all aspects—vehicle registration, licensing, integration with our sanctioning body, the United States Auto Club. It gets down into the media department, how we store images, how we retrieve those images, how we work with our media partners, how we upload things to Racer TV. It touches all aspects of our business.

“And then on the race weekend experience, it goes not only from scrutineering, either post-race or pre-race, but then also to in-race management as well,” Gill continued. “When they’re watching the race and they think something has happened they need to review, we’ve got to be able to roll that footage back. Where do we get that footage? How is it being stored? Initially it’s locally to the cameras and equipment onsite, but then it’s quickly put up to the cloud so we can reference it later and use it. That then gets into long-term storage decisions. If the stewards want to look at something and review something again post-race, restoring that information again becomes easily accessible. 

“Finally, it comes into long-term technical and balance of performance aspects. We’re uploading all the information, all the data points, from all the GT sessions so we have a robust picture of what’s going on with SRO racing literally around the world. We’re able to use data from a race that might have been in China, last weekend’s race in Belgium, a race coming up in Magny-Cours, France, or a race that might be going on at Phillips Island in Australia. You couldn’t do that if you were relying on a hard drive being shipped around the world. You’ve got to have instant access to it,” added Gill.

When visualizing a modern race car, it becomes clearer how cloud computing interacts with almost every facet of racing. “In motorsports, the cars are basically rolling computers,” said Angelo Comazzetto, from the Office of the Chief Information Security Officer with AWS Security. “The timing and scoring is like a mobile data center. And you’ve got the way that the spectators watch the action, which is done with a lot of computers and technology. And all of that is based on a venue like a motorsports arena, which is physical. There are cars and engines and tires and people running around. In that particular way, motorsports itself is very similar to a modern technological enterprise, because they are one. They are in the business of gathering data, trying to get as much of it as they can, and then trying to analyze it as fast as they can so they can ask questions and do things with the data.”

Richard Childress Racing (RCR) in Welcome, North Carolina, has teamed with Rescale for cloud computing resources for its NASCAR Cup and Xfinity teams. “Cloud computing has been used for our DOE analysis tools, running scrapers, and hosting dashboards,” said Keith Rodden of RCR. “By leveraging Rescale it allows us to do intense computing without being constrained to on-premise hardware, while we also benefit from having the ability to schedule jobs to irregular hours.”

Bipartisan initiative just endorsed by the Trump Administration would create more opportunities for PRI members to sell their parts to the U.S. military. Add your business to our letter to Congress as a supporter of the bill.  

PRI is endorsing the Warrior Right to Repair Act--a bipartisan measure in the Fiscal Year 2026 National Defense Authorization Act (NDAA) that would give the Department of War the right to repair and maintain its own equipment--and is encouraging its members to sign a letter of support. 

Today, the Department of War spends tens of billions annually to sustain its fleet of more than 420,000 vehicles--but outdated restrictions often prevent it from working with the small- and mid-sized American businesses best equipped to do the job. The Warrior Right to Repair Act would fix that, unlocking new opportunities for manufacturers, suppliers and specialty-equipment companies to compete for defense sustainment contracts. 

• For PRI members, the benefits are clear: new revenue streams, long-term business stability and the ability to apply motorsports innovation to strengthen national defense. For the military, it means faster repairs, greater readiness and lower costs for taxpayers. 

Recent global conflicts have shown the critical role small, adaptable manufacturers play in keeping vehicles mission ready. From heavy trucks to off-road utility vehicles, the ability to rapidly fabricate, retrofit and repair equipment can determine readiness on the ground. America's small businesses, the automotive aftermarket and the motorsports industry are ready to fill that role here at home. 

The Warrior Right to Repair Act ensures that the Department of War--and the businesses that support it--can repair, maintain, and modernize equipment without unnecessary barriers. 

PRI members are encouraged to sign our letter urging Congress to pass the Warrior Right to Repair Act.

NASCAR competition officials announced Wednesday that the target horsepower for Cup Series events at road courses and oval tracks less than 1.5 miles in length will increase to 750 hp in the 2026 season.

The horsepower figure will be an increase from the baseline 670 hp in the current rules configuration for NASCAR's top division.

The move comes amid growing demand from drivers, the industry and fans for a power boost to the Next Gen race car platform, which debuted in the Cup Series in 2022. The increase is expected to place a greater premium on drivers' throttle control, while also incentivizing tire management and creating more passing opportunities with varying on- and off-throttle times.

"I would say, like any other change that we are considering to the cars, we listen to the fans a lot," said John Probst, NASCAR executive vice president and chief racing development officer. "We listen to the drivers. We have stakeholders in the broadcast, OEM (manufacturers) and team competition and team business folks, so there's always no shortage of feedback that we get. Our fans are very passionate, they provide very candid feedback, so that all is very important to us."

Implementation will take place by using a larger tapered spacer on top of the engine's intake manifold, improving engine airflow and power. Achieving an even higher horsepower number would potentially compromise reliability and would require more development and cost, officials said.

The following tracks will allow for a maximum of 750 hp in 2026:

Road courses: Circuit of The Americas (TX), Watkins Glen (NY), San Diego (CA), Sonoma (CA), Charlotte Roval (NC).

Ovals: Bowman Gray Stadium (NC), Phoenix (AZ), Darlington (SC), Martinsville (VA), Bristol (TN), Dover (DE), Nashville (TN), North Wilkesboro (NC), Iowa, Richmond (VA), New Hampshire, World Wide Technology Raceway at Gateway (IL).

Officials indicated that a complete rules configuration and competition update briefing for 2026 would come in the offseason.

Sponsored by Hot Shot's Secret

In the world of diesel motorsports--whether it's pulling, drag racing, dyno competitions or other high-performance events--power is everything. But there's a vital element that too often flies under the radar in the pursuit of horsepower: lubricity.  

At Hot Shot's Secret, we've built a reputation for delivering not just performance, but protection. That philosophy comes to life in Adrenaline® Outlaw R100+™, a race-ready, high-performance diesel fuel engineered with one goal in mind--helping you win without compromise.  

Let's take a closer look at why lubricity is one of the most important features in a race diesel fuel, how Outlaw R100+ addresses it and why your engine needs more than just cetane to survive and thrive on the track.  

What is Lubricity, and Why Does It Matter?  

Lubricity refers to a fuel's ability to reduce friction and wear between moving metal parts. In a diesel engine, that primarily means the fuel pump and injectors, which are subjected to extremely high pressures and tight tolerances. Diesel fuel itself must act as a lubricant in these systems--especially in racing applications where components are pushed to their limits.  

While adding cetane is essential for increasing power, improving combustion and reducing ignition delay, it comes with a downside--cetane improvers tend to dry out the fuel, reducing its natural lubricating properties. This can lead to excessive wear on fuel pumps and injectors, increasing the risk of premature failure in mechanical and high-pressure systems alike. That's why it's crucial to pair high-cetane fuel with advanced lubricity additives. Without proper lubrication, the performance gains from increased cetane can be quickly offset by mechanical damage, costly repairs and inconsistent engine operation.  

Formulating A Race-Ready Solution  
 

Outlaw R100+ is pre-mixed and race-ready, taking the guesswork out of blending your own brew of additives. The base fuel distillation is hand-selected by our team for its naturally high cetane, lubricity and BTU (energy) properties. From there, we layer in an impressive concentration of cetane improvers to deliver serious power gains. Increased cetane aids in reducing cranking time, quicker turbo spool, less ignition delay and smoother cylinder pressure peaks. The result is more efficient, complete combustion--and more power to the wheels.  

But unlike many high-cetane fuels that sacrifice protection for performance, Outlaw R100+ includes Adrenaline® Racing Top Lubricant™, our proprietary upper cylinder lubricant formulated to deliver the highest level of lubricity improvement available. Racing Top Lubricant protects critical components by adding essential lubrication where it's needed most--reducing fuel system wear plus protecting the upper cylinder parts from scuffing, improving ring seal and lowering friction between the cylinder wall and piston ring interface to boost performance and reliability.  

Proven Performance: Lab-Tested, Track-Winning Fuel  

The performance of Outlaw R100+ isn't theoretical--it's proven in the lab, on the dyno and at the track. Using the ASTM D613 engine dyno test, R100+™ recorded a cetane number greater than 100, the scale tops at 100, placing it at the absolute peak of what diesel can deliver. Lubricity performance is equally impressive, with a wear scar measurement under 420 microns, exceeding industry standards and protecting components under extreme racing conditions.  

And when it comes to real-world dominance, look no further than the 2025 Ultimate Callout Challenge (UCC). Josh McCormack, the 2025 UCC Champion, trusted Adrenaline Outlaw R100+ to power his truck to the top spot--becoming the only competitor to break the 3,000 horsepower barrier on the dyno and winning the overall event. Recently, Josh extended his dyno records at Diesels In The Mountains with 4157 HP corrected and 4461 HP corrected at Diesel Days Truck Rodeo. These aren’t just wins--this is a statement.  

Power and Protection  

It's easy to get caught up in big horsepower numbers, but behind every dyno chart and every pass down the track is a set of components working under extreme stress. Fuel injectors cycling thousands of times per minute. High-pressure injection pumps pushing diesel at over 30,000 psi, mechanical pumps pushing RPM limits of the designs. Protection is a necessity, not just an option.  

 

Outlaw R100+ exceptionally high cetane rating delivers faster, cleaner combustion. That means quicker turbo spool times, allowing your engine to hit peak boost sooner and deliver power when you need it most. You'll also notice easier starts, even in cold conditions and lower EGTs, reducing stress on pistons, valves and your turbo system over the long haul.  

A proper lubricity agent like Racing Top Lubricant reduces wear at every critical interface in the fuel and combustion systems. Injectors last longer, fuel pumps operate more efficiently and need to be rebuilt less often--delivering more consistent compression and sharper throttle response with every run. The power gains from high cetane are fully realized--and sustainable--because you're not sacrificing durability in the name of performance.  

Why Pre-Mixed Matters  

One of the biggest advantages of Adrenaline Outlaw R100+ is that it's pre-mixed and ready to pour. In the racing world, precision matters. Every variable--ambient temperature, elevation, boost pressure, tuning strategy--can affect your results. So why add uncertainty by blending your own fuel cocktail trackside?  

Outlaw R100+ eliminates that variable by giving you a professionally engineered, lab-controlled formulation that ensures consistent performance in every gallon. The balance between cetane and lubricity is dialed in by our chemists and proven by our racers. You don't have to wonder if you added enough lubricity additive or if you've over-treated your fuel. It's already been perfected for you.  

Compliance Without Compromise  

We didn't just build this fuel to win races--we built it to meet the requirements of the sanctioning bodies that govern them. Adrenaline Outlaw R100+ complies with regulations from the Pro Pulling League, NTPA, ODSS, NHRDA and more. That means you get the power, protection and peace of mind that your fuel won't get flagged before you even make it to the line.  

Whether you're running in a local event or competing nationally, you can trust that Outlaw R100+ gives you a legal edge--one that's been tested and approved at every level of competition.  

The Bottom Line: Power + Protection = Performance  

In diesel motorsports, you shouldn't have to choose between power and protection--and with Outlaw R100+, you don't. This pre-mixed, high-cetane race fuel delivers over 100 cetane and industry-leading lubricity, giving you the horsepower you want and the engine protection you need. Whether you're chasing dyno numbers, track wins or pulling titles, Outlaw R100+ is the competitive edge that keeps your engine performing and protected, run after run.
