so..I have 10.1 static and 8.8 dynamic and run on 91 with close chambered heads. I would say cylinder pressure plays a big part in it all.. Also this engine was built by Brian at IMM. 33 degrees timing.
Cylinder pressure , what is yours ? My motor was built 6 years ago so I am not sure on exact compression , but do remember it took forever to get it to run without pinging , compression was over 10.1 I know that . Each cylinder was between 192 and 195 lbs , that I remember . I put in 90 octane once by mistake and it ran like crap , ran on when I shut down , constant ping as soon as I hit the pedal .
I'll try to find the build sheets so I can give better numbers . Memory is not great , between getting old and being put under general anaesthetic 5 or 6 times in the last 5 years I'm lucky if I remember my name .
