Re: (doh) compression test results (archive)

If it helps you any, here's a picture of my GF's M5 comp check. I do not have one on mine but the butt dyno tells me her car is just as strong if not more then mine.

I think more important is that all cylinders stay close to each other in terms of compresion. I would be more concern if three cylinders read 170 and the rest were 140's.

JMHO

as usual pls (anyone)chime in if I am missinformed

Miguel

145 145 150 150 145 145

or somethign like that. They were all 145 or 150.

Motor has 106k miles.

AFAIK, this sucks :)

Neil seemed to say something to the effect of CR should be about 14.7*CR - on my car that'd be 14.7*9.8 (the US S38B35 was 9.8:1 stock, right ?)

which gives 144 psi

Which means my motor is doing fine. HOwever, everyone expected it to be around 160-170psi.

Given that the motor isn't making as much power as it should be.. im inclined to belevie my compression is low across the board, and hte motor is just tired :(
