COMP Cams is bringing the musclecar sound back and it's nastier than ever! Let's face it, few things serve to grab our attention at a car show or cruise night more than a car with a thumping high performance idle. In fact, one of the most frequent questions fielded when customers call our tech line is, "what camshaft will give my car that mean-sounding idle?" In an ongoing quest to provide you with the performance and sound you demand, COMP Cams' engineering team proudly introduces the Thumpr series of camshafts. The Thumpr camshafts are a new series of retrofit hydraulic roller camshafts designed for use in engines that were originally equipped with flat tappet camshafts. 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. They give you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in three different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. These Thumpr series camshafts feature a cutting-edge hydraulic roller design that delivers a substantial power increase over identical hydraulic flat tappet grinds without sacrificing reliability or ease of maintenance.
