Prayoonto Racing Camshaft Stage 2
Prayoonto Racing Camshaft Stage 2 For Sale: Our Signature Series Camshafts are the ultimate in high performance, produced from aerospace grade 8620 steel billet material and CNC honed on state-of-the-art cam grinders. They give the highest stiffness at extended RPM ranges while decreasing possible valve float.
Through intensive testing, we have witnessed 10-15 horsepower boosts on NA systems and 50+ horsepower gains on forced induction applications, using entirely stock engines. With a higher compression ratio, stroke, and bore size, you may expect to make even more.
The stage 2 camshaft is most commonly used and combined with K20 bottom ends. We normally recommend stage 3 and 4 camshafts for K24 bottom ends, both stock and fully constructed. This camshaft profile focuses on mid-range response while maintaining great top-end flow. We recommend that our K20 autocross, dirt track, and time attack drivers use this camshaft to wake up their powertrain. Using the prayoonto stage 2’s, my own K20A2 longblock produced 703 horsepower at 25 PSI. Even at 9500RPM, the dynograph displays no leveling out. The engine could still produce more horsepower, but my fuel system was maxed out.
