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 CAM HELP® tech line is “what cam will give my engine a mean-sounding idle?” In response to this popular demand, the COMP Cams® engineering team proudly introduces the Thumpr™ series of camshafts.

The Thumpr™ Camshafts are a series of hydraulic flat tappet and hydraulic roller camshafts that are now available for most popular applications, carb and late model efi.

The reason that the new Thumpr™ Camshafts have such an aggressive exhaust note is that the lobe profiles and grind characteristics chosen by the COMP Cams® engineers produce a combination of early exhaust valve opening, long exhaust duration and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams without negatively impacting the power output or streetability.

Thumpr™ Camshafts are available in three different grind profiles for each engine, all of which will produce a rough, racy exhaust note and impressive amounts of horsepower and torque. Their cutting-edge design means that they will deliver a substantial power increase over "tamer" camshaft grinds without sacrificing reliability or ease of maintenance.
