COMP Cams engineering team proudly introduces the Thumpr series cam and lifter kits. The lobe profile and grind characteristics of these new Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine.These Thumpr series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.
