Tomei presents the popular poncams. Generally, engine tuning is to modify the torque characteristic of engine by changing cam duration timing and height of the cam lift, so as to gaining maximum torque and horse power. However, when tuning the engine strictly, it should be carried out with the idea of securing effective area of the valve not only by duration timing and height of the cam lift, but also by through improvement of its intake efficiency.
High valve lift allows huge amount of air to flow in, yet it mechanically damages the system and gains friction loss. Also, wide cam duration will deriver great power at high RPM, but it gives rough engine character at low RPM too. Tomei have worked to get an ideal well-balanced profile of camshaft and succeeded to give it 1.3 to 1.5 times more effective area than regular camshafts
Tomei have been developing and producing their original camshafst ever since TOMEI established. Still today, they are providing high performance camshaft to many racing teams and winning lots of titles.
Type A
In order to get stable idle and raise low-mid RPM torque, we set the duration of EX camshaft shorter.
Best suit used with stock turbine or N1 turbine.
Type B
By giving longer duration timing than type a, it eables to raise both response and peak power at the same time, even with mid-large sized turbine.
