Ok, so if a guy wanted to figure out what the "perfect" lossless compression measurement is on a motor, how does one go about it? i.e. somebody tells you to "Do a compression check"... you say "ok, what values dictate good?".. they respond back with some arbitrary number somewhere in the high 100's.. and that's my question: Every motor should have an ideal reading, how do you figure that out?
I assume you deal with bore/stroke/compression ratio/head gasket thickness/domed-dished-flat top piston and chamber size and through some magical formula you get a reading of xxx psi is possible? Google is letting me down on this one... Wallyman
