What is the max boost I can run on the following compression ratios with 91 octane gas and no meth? This will be a turbo application.

10:1 CR

9.7: CR

Kind of depends on lots of stuff like type of pistons, cylinder heads etc. But Id say generally you will probably find itll take anywhere from 8 to 11 lbs of boost before u get knock.
