P10227: FSAE Variable Intake
/public/

Product Concept 1

The variable length runner concept has been proven and implemented in both motorsport and production vehicles. The first publicized application was on the Mazda 787B LeMans race car in 1991. The 2.6 liter rotary engine was outfitted with continuously variable intake runners that were actuated with a cable and pulley system. The Mazda team found an increase in peak torque, as well as a broadened torque curve by implementing the system.
