The Camshaft is a masterpiece for the engine, it is one upgrade that can massively increase the performances of your favorite car.
When upgrading the engine, two parameters of the camshaft can be changed : the duration of valve opening and the valve lift.
By increasing the valve lift, you increase the air-fuel flow, so for the same opening time, you capable to increase the volume of air-fuel mixture in the cylinder, that will increase the power in high revs.
By increasing the duration( measure in degree ) , you increase the period while both exhaust and intake valve are open, the exhaust gases will help the fresh gases to enter in the cylinder by creating an suction effect. It will increase the air/fuel flow and the power.
