COMP Cams Thumpr Retrofit Hydraulic Roller Camshafts

COMP Cams is bringing back the musclecar sound—and it's nastier than ever! Few things grab our attention at a car show or cruise night more than a car with a thumping high performance idle. In an ongoing quest to provide you with the performance and sound you demand, COMP Cams' engineering team proudly introduces the Thumpr retrofit hydraulic roller camshafts. They are a series of camshafts designed for use in engines that were originally equipped with flat tappet camshafts. The lobe profile and grind characteristics 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. COMP Cams 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.

COMP Cams Big Mutha Thumpr Hydraulic Roller Camshafts

COMP Cams Big Mutha Thumpr hydraulic roller camshafts are perfect for folks looking for great performance and wild camshaft idle. The basic science behind the Thumpr cams isn't new. This cam line delivers true high performance engine sound by "tightening" the lobe separation angle of the camshaft. This, in turn, creates more overlap between exhaust and intake events, as well as more aggressive performance sound. Available in different grind profiles, each Thumpr cam produces impressive horsepower and torque performance within a different RPM range. If you're looking for a cam that makes your engine sound meaner than it is, the COMP Cams Big Muthra Thumpr cams could be the right call. Order the model recommended for your year/make and engine application.
