The "Twister" is a High-performance grind providing significant power increase over the stock cam at a great price. Developed on the dyno and the track to maximize power on GX270s, GX390s, 420 Predators and 13/15hp Chinese OHV.
Stock lift with increased duration and optimized valve timing for a wide powerband (2000-5000+ rpm) providing a drastic improvement throughout the entire RPM range. This cam is easy on the valvetrain and will not "beat up" your valves or lifters. This cam is designed for engines operating at 5000 rpms or less. Use above 5000 rpms or with springs heavier than 50 pounds is not recommended.
Recommended for Yard Karts, Mud Motors, Short Track Go-Karts, Marine, Pulling/Towing, Mini-Bikes and anywhere else where a broad powerband is needed and loss of low end is unacceptable. Also great for racing classes that require stock lift.
Cam is cut on a close base circle to the stock cam so the compression release is still functional.
246 Duration, .260" Lift using stock rocker arms (.250 at lobe), 110 LSA (ICL varies depending on engine installed in)
Use HD Single Valve Springs Only (no dual springs)
