Description

Maximum-effort centrifugal-supercharger cam for high-RPM, high-boost LT engines.

117.5° LSA widens the powerband and stabilizes airflow under extreme boost levels (15–25+ psi).

Large 239/257 duration set delivers exceptional top-end boost utilization and high-speed airflow.

Idle quality: very choppy, unmistakably race-inspired—intended for serious builds.

Best paired with forged internals, ported heads, large intercoolers, and high-flow fuel systems.

Power gains vs. stock: +120–160+ HP depending on blower configuration and boost.
