Cam Options and Recommendations

MILD Camshaft:
This versatile cam is ideal for street driving, drag racing, circuit racing, time attack, and drifting. It enhances quick turbo spooling and offers excellent throttle response, making it popular for builds in the 450-800HP range. For the best performance and reliability, pair it with a high-performance valve spring kit.

SPICY Camshaft:
Designed for high-powered builds targeting 750-1000HP, the SPICY camshaft suits aggressive driving and works best with a turbo size between 62-72mm. Ideal for drag racing, roll racing, pro-level drifting, and road racing, this cam delivers a shifted power band to mid-to-high RPMs. A high-performance valve spring kit is required to support the increased load and RPM range.

WILD Camshaft:
For extreme performance and turbo builds over 1000HP with turbos 72mm or larger, the WILD camshaft provides unmatched high-RPM power and is tailored for high boost applications. Engineered for drag strips, large turbo setups, and aggressive driving, this cam also requires a high-performance valve spring kit to maintain performance and durability.

Please note that all camshafts must be installed by a professional who can verify piston-to-valve and valve seal clearances to ensure proper functioning and safety.

If you aim to increase RPMs to 8500-9500, the solution is in transitioning to solid lifters. Don't hesitate to discuss your engine build with our experienced advisors at Sales@5150autosport.com
