How does volumetric efficiency effect horse power?
VE is a measure of cylinder filling and exhausting to show potential increase or decreased horsepower. Higher VE increases horsepower. VE changes through the rpm range and for racing applications is optimized for the upper rpm range with a sacrifice of VE in the lower rpm range. Things like camshafts and rocker arms, intake ports and length, carburetors, combustion chamber type, valves position and size, exhaust ports and length, header size and length all effect VE.
