Sprint Car tune-ups are featured in our new publication: High HP Tuning for Mechanical Fuel Injection.
UpDate: due to rain on Fri, Team Broddie was rescheduled to run through Sun Mar 26. The Saturday event was great. ProMod horsepower was apparent. A couple blown alcohol setups; my favorite, were there as well. A large crowd of racing enthusiasts gathered to join the fun. An atmosphere in the air of fun & racing competition!
Team Boddie‘s promod drag race is scheduled this weekend, Fri Mar 24 & Sat Mar 25, at Sacramento Raceway. Email us if you will be there, and we’ll look you up. The show will be filled with grudge racing, high horsepower drag cars. The crowd is always enthusiastic at this event. A lot of charm and excitment.
Mechanical fuel injection is holding its own against EFI and racing carbs in racing. It is simple, lower cost in many applications, and good for fuel pressure increases for more response & power. One recent application tested racing carbs, EFI, and mechanical fuel injection all on the same racing engine. Another recent application tested mechanical fuel injection against racing carbs in a factory developed combination. In both applications, mechanical fuel injection was good for about 5% more horsepower. Fuel pressure is limited in common EFI racing packages. Reduced flow from the venturi’s is a limit in carbs.
