I did a compression test on my motor yesterday. I have a b20 block and a gsr head 11.6:1 compression pistons. Cyl. 1 270, Cyl. 2 230, Cyl.3 225, Cyl. 4 230 anything seem wrong with that im jus concerned about the cyl 1.

Redo it again. 270 is really high you sure there was no oil in the cylinder? Do the test again and see if the same numbers come up. Also was this wet or dry?

270??? Holy ****. That's insanely high even for the higher compression you're running. Run the motor up to operating temp and do the test again. Maybe you cranked it over one too many times? Hell, peobably wouldn't matter I guess. Usually you have a good reading after just a couple compression strokes.
I'd say redo your test with the block nice and warm.

::Edit::
Just for the hell of it....I had
1 - 140 psi
2 - 15 psi
3 - 0 psi
4 - 40 psi
after I blew my motor up.

The car was nice and warmed up. As far as i know there was no oil in cyl 1. Im gonna do a leak down test some time next week hopefully. The motor cranked over the same times as cylinder 2 3 and 4.

Oh well i'll jus wind up pulling apart the motor sooner then i was gonna do. Thanks for ur help i jus wanted to make sure i wasn't the only one who thought 270 was pretty damn high.
