Calculator suggests around 9.1:1 c/r.....10 psi high octane....dont risk it.....Any higher
Use water meth/boost cooler and keep it reliable.....
Dont go to insane with the timing.....More power also means more boooooooooom!!!!!!!
A thicker mls headgasket will lower your c/r...as well.....ahaaaaa
Did you think of that?I dropped a whole point in my tt project car./....

10lbs and 91 octane with a safe A/F and timing will be just fine. if ur wanting more, like 14lbs that's when I would mess with higher octane and/or meth.
9.1 scr is what I got.
