Overlap promotes cylinder scavenging at high RPM's which is crucial to power production in a naturally aspirated engine. Stand on the gas pedal at 2500 RPM, and the phaser advances the intake cam to provide maximum power. The camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position. Which both the intake and exhaust valves are open at the same time. It turns out that there is a direct relationship between the shape of the cam lobes and the way the engine performs in different speed ranges. The key parts of any camshaft are the lobes. Ever wonder why hotrods sound like they do at idle? As the camshaft spins, the lobes open and close the intake and exhaust valves in time with the motion of the piston. I intend to offer insight which will help in choosing a camshaft for yourself.
