Ok to boost with these compression numbers?

1) 1462)1493)1474)149

wow, thats great. as logn as you dont range between 30 psi between any cylinders..but damn. thats luck

[Neejay]

Im glad to see that those numbers are good, because I got 152 on all 4 of mine last year.

I was thinking that 152 was too low. w00t

[hannibal]

factory spec is 179psi, with a minimum of 151psi and 14psi variance between cylinders.

Make sure the car is warmed up before you test and follow the procedure in the FSM exactly. Your numbers are low, but dont have a lot of variance between them.

i say they are good enough as long as they are close. if you want reassurance, warm the engine up completely before the next test, and give it WOT while cranking.

next time you test pour some engine oil down the spark plug hole before you put the compression tester in to see if that improves your compression any. if it doest then your rings are likely worn, but you would have to change them anyway eventually, so i say boost away

remember to pull your fuel pump fuse

where can i go to look at step by step procedure for a comp check

[Craving4Boost]

look at the factory service manual.

factory rebuild after 149 psi. but hrmm

[WDRacing]

I bet your numbers are good, just a variance of some kind. They are close, which is a good sign, I doubt all the cylinders went that low at the same time.

Boost away man.

Boost, Boost, Boost away. And when it blows up, rebuild with forged pistons and rods and Boost some more.
