Our 5150 Turbo camshafts have a well-established track record. They have been successfully employed on both our personal vehicles and those of our customers for more than 15 years. Extensive hours were dedicated to testing various camshafts and meticulously comparing the results. We take pride in offering our customers only the very best-performing camshafts! Note: Camshafts ONLY. Lifters sold separately. The MILD option exhibits impressive versatility, catering effectively to street driving, drag racing, circuit racing, time attack, and drift applications. It delivers quick spooling and enhanced throttle response for both on and off-throttle driving styles. This camshaft is frequently favored for vehicles producing horsepower ranging from 450HP to 800HP. We strongly recommend using a high-performance valve spring kit with this option. For those seeking higher performance, the SPICY option is ideal, intended for cars generating 750 to 1000 HP and equipped with turbo sizing of 62-72mm. This camshaft suits aggressive driving, especially in conjunction with performance intake manifolds. It is well-suited for drag strip racing, roll racing, pro drift level, and road racing. The power band is shifted to mid and high RPMs, although it sacrifices a little spooling. For optimal results, a high-performance valve spring kit is mandatory. For the most extreme performance requirements, the WILD option comes into play. Designed for cars producing 1000+HP and equipped with turbo sizing of 72mm+ with high boost, this camshaft is tailored for aggressive driving, drag strips, big turbos, and high RPMs. Similar to the spicy option, it necessitates the use of a high-performance valve spring kit. 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.
