COMP Cams® Thumpr™ Hydraulic Roller Camshaft Kit
 

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 camshaft will give my car that mean-sounding idle?” In their ongoing quest to provide customers with the performance that they demand, the COMP Cams® engineering team proudly introduces the Thumpr™ series of camshafts.
 
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 at a specific rpm range.
