So just did a compression test on the Termninator and all cylinders came back 180psi, on a 85,000 miles car. Is this a good result? Any feedback is welcome. Thanks -Gabe

thats great almost too great!! Ive been told its the spread thats more important. Mine was 150 to 140 range, you just dont want to much lower on any one cylinder. I think a good number is 165, so if all of your cylinders are in the very close proximity of eachother, id say your looking good.

+1, 180 on all is really good.

Nice, thats what i needed to hear. Cause I've been having trouble on a dyno for a couple of days and the car isn't getting the power I "beleive" it should have. Also it's on a low reading dyno so I don't know.

Are they all 180 exactly? Or do you have an actual breakdown by cylinder? Seems a bit odd if they are all exactly the same.

Those are great results if done on a hot, dry test.

Mine all showed 185-195 at 60,000 miles. The numbers aren't as important as the spread. You want all cylinders to be within 10% of each other.
