Compression test result

[4wd-Eclipse]

I did compression test on my overhauled engine after breaking-in for 950km and the result is 185 psi in all cylinders. So is this a good reading for 9:1 piston with metal head gasket

sounds about right to me

I have 180 compression is all 4 cylinders in my bone stock 200,000km motor...I would think going to 9:1 would bump up the compression a little more then that...

Nahhh...thats good stuff. Mine was 185psi straight across after I broke my motor in to (9:1 Ross').

MHG are usually a bit thicker than stockers... and 185psi across is AWESOME
