The COMP Cams Thumpr 227/241 hydraulic roller cam delivers an audible, aggressive idle and enhanced midrange for street applications. It favors engines fitted with supportive heads and higher compression, producing a more energetic throttle response in the upper rpm range. Best used where a lively, characterful idle and stronger top‑end breathing are desired without full race preparation.
