| Generally, engine tuning is to modify the torque characteristics of an 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 the 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 a huge amount of air to flow in, yet it mechanically damages the system and creates friction loss. Also, wide cam duration will deliver great power at high RPM, but it gives rough engine characteristics at low RPM too. Tomei have worked to get an ideal well balanced profile of the 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 camshafts since TOMEI was established in 1968. Still today, they are providing high performance camshaft to many racing teams and winning lots of titles in the process. |
