compression

85 compression across the board but car still seems to run good as long as the boost is under 21 pounds on an evo 3 16 g is that normal

85psi of compression is well below the service limit

Holy crap, there needs to be another 100 in there somewhere.....yikes..

And it still runs "good"?

ya that is what surprise me i did a dry test with a brand new mac tool compression tester i have been told that anything below 100 run like crap or dosent run at all

My 160k mile awd ran 'decent' with only 120psi across. Rebuilt but not running yet damnit!

So have you started tearing into it yet?

Bad rings or what?

no i haven't yet don't have the money to get all the parts i need so i am kinda babying it right now OK that's a lie i em now that my comp is that low but i just checked it few week ago so ya know i plan on doing it this winter. That's why i didn't make it to the meet you guys had in lynwood didn't think i would make it on that bad of compression didn't wont to risk it but i still think its weird that its run's pretty descent as long as i don't run over 21 psi if i run 21 psi i have detention problems it seems to like 14 to 16 psi
