[QUOTE="heytonyman, post: 14442650, member: 32079"] Gas equivelant 11.5 MINIMUM. You're talking about pushing it hard with big boost so I'd suggest 11.0-11.2 if you want a long healthy life with stock pistons. The extra HP gained by leaning it out comes at a price... HEAT. Change the pistons to something with some more PTW and ring gap clearance and you can run it a bit hotter / leaner without fear of dragging a skirt. Stud the heads and the sky's the limit. Lower IAT's is basically free power. You haven't specified your setup but big boost with roots / twin screw blowers comes with high IAT's. Consider a small dry shot of N2O to cool it off if you're going to push >25psi. [/QUOTE]
