I did my test and got these numbers....and this is without the butterfly valve at wide open throtle

Cylinder 1- 215
Cylinder 2- 200
Cylinder 3- 220
Cylinder 4- 205

Are these o.k. cause they're all within 10% of eachother?
Would these be in the "normal" 230-240 range with WOT?

let me know guys...thanks

 

my friend tested his the other day and he was at 230 across the board. but my friend with a fully build gsr tested his it was at 280. i thing you might have a different headgasket.

 

I would get a bore scope . And do a leak down test . Cuz the 200 in #2 could turn into 180 in no time .

how much would a bore scope cost and how difficult is a leak down test?

 

If you have decent hearing and a compressor with some decent output , you can do a leakdown test . But to buy a leakdown tester or a bore scope , I hope you didn't spend all your money on that motor . Try Craftsman and Mac tools .

Before you waste time and money on a leak down test, why don't you do the compression test right??? Doing any test half-*** isn't going to tell you anything!!!

Def do it again at WOT. Your values may change significantly.
