.It is not standard camshaft.Changing the large angle camshaft can increase the time of air inlet, change the engine performance, the power of the compression explosion increases greatly, and the horsepower and torque increase are significantly increased!
The camshaft is one of the key components of the engine. The hardness of the cam tip and the depth of the white layer are key technical indicators that determine the service life of the camshaft and the efficiency of the engine.The large angle camshaft can extend the valve opening time, increase the valve lift,and make the intake and exhaust valves open early and late, allowing more air to enter the cylinder to improve the engine's medium and high speed power and output.It can enhance 20% output power.
