It’s official—Ryan Martin is locking in his game plan for the 2025 season of Speed Promotions No Prep Kings. After experimenting with both his Fireball Camaro and the gray car last year, Martin has decided to stick with the ProCharger setup on the gray car for the majority of this season. The decision comes after a back-and-forth season in 2024, where he switched between his two cars, each equipped with different power adders.

Why the Gray Car?
Last season, Martin started off with the Fireball Camaro, which ran a screw-blown Hemi. However, he later switched to the gray car, which was also equipped with a screw blower. While both cars had their strengths, running two different setups split his focus, limiting the data collection on each car.
Despite the Fireball Camaro clocking higher speeds—reportedly hitting 205 mph—the gray car proved to be more consistent on no prep tracks, especially in hotter conditions. With track conditions playing a crucial role in No Prep Kings racing, reliability and consistency often outweigh raw speed. This is exactly why Martin is putting his focus on the gray car for the upcoming season.

ProCharger + Liberty Transmission = Winning Combo?
One major change for 2025 is the addition of a Liberty transmission to the gray car. The ProCharger setup has already proven itself to be highly tunable and effective in No Prep Kings racing, and with the Liberty transmission now in play, it could provide an even greater advantage. Martin himself has confirmed his commitment to this setup via a live feed on his Facebook page, stating that the ProCharger combination simply offers more consistency than the screw blower under no prep conditions.
How the Rules Could Impact the Competition
A key unknown factor heading into the season is the rule set for Speed Promotions’ No Prep Kings series. While the race schedule has been released, official rules have yet to be updated. Given how close the racing was last season, minor tweaks to the rulebook could make a big difference in competition.

Screw blowers have struggled with consistency compared to ProChargers under current rules. However, if rule changes—such as allowing a 36-inch tall tire—are introduced, screw-blown cars could become far more competitive on no prep surfaces. For now, though, Martin’s choice to stick with the ProCharger setup appears to be a strategic move based on past performance.
What’s Happening with the Fireball Camaro?
With Martin focusing on the gray car, what does that mean for his iconic Fireball Camaro? According to reports, the Fireball will be making a shift to 275s, joining a growing number of Street Outlaws cars that are transitioning to this tire setup. Several other racers have had success running 275s, making it an interesting development to watch as the season progresses.
Final Thoughts
As No Prep Kings continues to evolve, racers are always looking for the best combination of power, consistency, and adaptability. Ryan Martin’s decision to commit to the gray car with a ProCharger and Liberty transmission suggests he’s aiming for a strong, consistent season rather than chasing peak speed alone. With rule changes still pending, it will be interesting to see how other racers adjust their strategies and whether Martin’s setup will prove to be the winning formula in 2025.
