I need to say more about this. you could think about compression ratio in
simple terms 14.5 and so on. But cyl. pressure loss needs to be
considered[ by the rings- valves ]. Also static comp. is far less than total
comp. Say at 5000 rpm. cyl. losses are less. Comp. happens so fast it can
not escape. Bradford

It's just a ratio. If ten is the total intake, 1 is the area compressed.

Can someone explain why a 10:1 compression ratio does not result in 145 psi
in the cylinders when the ambient air pressure is 14.5 psi???
I've been wondering about this for some time... Even with different cam
overlaps & durations, the final (peak) compression should register as such
on a compression gauge, right? (or wrong?)
