One of the methods to increase the engine power is the installation of a higher-grade exhaust shaft than the standard. As a result of the camshaft modification, which is one of the oldest and most efficient methods, a power increase of up to 35 percent is achieved. High-grade versions keep valves open and close long, allowing more fuel and air to enter the combustion chamber per unit time. Therefore, more burning takes place. This means more power.
Depending on the angles and structure of the cams on the shaft, torque or power is affected. Pointed cam shafts open the valves early to increase torque, while large crested cams are preferred to increase power. The high degree of camshaft also increases the idle speed of the engine. However, doing so may cause the engine to run unstable at idle. For an efficient modification process, it is useful to develop other mechanical and electronic parts that provide the movement of valves outside the camshaft. For example valves, valve springs camshaft pulleys, such as the brain program ignition system. The price of the CrompCam brand camshaft is around 250USD.
