  • Thumpr ™ Cams make a bold statement at stop lights and around the neighborhood with the radical sound of a hard hitting, thumping, high performance idle. Designed as a bolt-in for 110c.i.-117c.i. engines but really shines with performance heads and higher compression. Can be used as a bolt-in cam for 103c.i. engines but higher compression is needed. Larger throttle body is a plus with Thumpr ™ Cams, 58mm and up show big gains in acceleration and throttle response. Sophisticated “Endurance Ramp” lobe design makes great power but is easy on the tappets and valve train for long life. Very wide power band, pulls great up to 6000 RPM.
