This nitrided COMP Cams Thumpr cam is intended for high-performance street/strip use, requiring 9:1+ compression, a 2500+ stall converter and supporting intake, gears and headers. It produces a rough idle while delivering strong power when combined with proper drivetrain and breathing upgrades. Nitriding enhances surface durability for the intended aggressive use.
