The wiseco pistons available for the 7M increase the compression ratio to 9:1 from what i read. Special orders need to be made to have stock compression.
I've searched and seems a few people are running wiseco pistons. For the ones that are running it, what have you done about the compression ratio, or you didn't know/care about it? Are you just running less boost, and/or race fuel?
I know i can run lower boost and not have to worry about it. But for big boost, lower compression is better.
How much does 9:1 compression change things?
What size headgasket can be used to compensate and lower the compression ratio? What's the formula to figure that out for all you engineers out there?
