No 360 or 305 Sprint Car can be ready to race without the double digit horsepower and torque gains produced by the massive air entry profile that these revolutionary stacks provide.
Torque Creates Acceleration and Horsepower makes Speed!
R2C's new CFd designed "Big Mouth" Magnesium Alloy Injector stacks for 360 and 305 cars provide unmatched levels of both.
Bolt on 16 lb./Ft. of torque!
CFD Intake analysis of Sprint Car injection systems illustrated the importance of a wide entry profile and a smooth transition into the 2 3/16" tube diameter in order to maximize performance and improve throttle response. The result is maximum corner pulling power to drive you out front and keep you there.
Elimination of raw edge turbulence at the Siamese area dramatically improved the flow path. R2C's innovative 360 Sprint Car stacks offer racers unmatched performance and value. Independent dyno testing exceeds all current designs.
