just thinking... as you rev, you have less and less time to try to fill that cylinder so thats less volumetric efficiency and so less pressure as the revs increase. Only way hp can increase is by adding more events per time. So any blown gaskets could well be caused by slight detonation rather than actual firing pressures blowing out the gasket because max cylinder pressure (and volumetric efficiency) occurs at torque peak.
HORSEPOWER FORMULA
P= pressure caused by the firing
L-length of stroke
A=Area of bore
N=number of firing times per minute.
Change anything in the above horsepower formula and you change hp.
Maximum torque occurs at maximum cylinder filling which is also point of maximum volumetric efficiency.
