The pursuit of the optimal profile
The profile of these camshafts were designed to aim for maximum efficiency of the valve opening and closing duration. These PROCAMS were designed with a quicker valve opening time and a gentle closing time to provide stability to the valve seat rings.
This lightens the stress applied to the all the surrounding components of the valvetrain and decrease unwanted noises.

Accommodates to high RPM
Each and every profile with varying duration and lift listed below are designed to perform the best during 4,000~10,000 RPMs.
