Having installed more than 90 sets of the PONCAM TYPE-R camshafts the feedbacks I have received is that this camshaft profile is very “gentle”. The meaning behind it is that both Torque and Power produced by these cams are the best balance from low to high engine speeds. Smooth overall balance. It is not the case of the camshaft profile alone but the case after numerous tests that have been done. A camshaft is neither the main factor of an engine nor is it a main factor in engine performance levels but for overall performance balance and for best drivability I always recommend Tomei Powered Camshafts.
