COMP Cams Big Mutha Thumpr hydraulic roller camshafts are perfect for folks looking for a hot performing cam that delivers great performance and wild camshaft idle. The basic science behind the Thumpr cams is not a new one. The Thumpr 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 "cool" 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.
