So yeaaaaa out of sheer boredom at work i decided to do a compression test on my motor and this is what i came up with:
Engine is moderatly warm.

CLY1=105psi
CYL2=105psi
CYL3=104psi
CYL4=103psi

When i searched for compression test results i saw people coming up with 140psi numbers and new SR motors should be around 200psi...this blew me away, i didnt think that compression numbers were supposed to be that high. Should i pull the head and check her out?? This is a stock sr with stock boost, stock cams just the normal bolt ons, FMIC, Tubular mani, exhaust. Thanks guys
