compression ratio for supercharged xr4i
What is the best compression ratio for a 3.1 cologne v6.
i want to run a sprintex supercharger. But my engine has a compression ratio of 9.9:1 now.
Is this to high to run a intercooled supercharger at 7/8PSI?

Don't think your boost of 8psi will be too much. I guess it depends how well it it mapped/tuned and cooled.
Would have liked to have seen forged pistons but saying that some pistons are squeeze cast which again are stronger than cast.
Hopefully Stevie will see this thread and help you out.
