WebWhat is valve overlap and why is it important. Valve overlap is mostly a function of duration and lobe separation angle (LSA), and to some minor degree valve lift. If the LSA remains the same but you increase the duration, the amount of overlap will also increase. Overlap is the span (measured in crankshaft degrees) when the exhaust valve and ... WebBack to Calculators Index. Use this calculator to see what the effect of bore, stroke, rod length, cam timing, compression ratio, boost pressure and altitude is on your dynamic compression ratio. Of the variables, the most important is cam timing which has a dramatic effect on your "dynamic" as opposed to your static compression ratio. rayleigh toyota rayleigh
