Post Compression question
Anyone ever have a stage 2 GTR with 165 psi on both cylinders? motor was built by SETX performance, and was at 162 before I got the crank and flywheel balanced, and put new rings and at 165 again(where it was when I bought the motor used with 85hrs on it). just curious, will push my 1750 dfou special right at 30-32 with a unworn gt 2 blade 10p. still doing right at 28 - 28.4 with 4 men and hunting crap.

just curious on opinions.

I had an setx motor recently in shop with same compression as u have. I believe your heads were already shaved when you got it.

Yes supposedly around forty thousandths, but can get no confirmation on that. And I was just checking to see if that was anywhere near normal when you hear number constantly over 200.
