Numbers seem a little low. What's the compression ratio on that engine? Also what tensioner are you using?

Stock cobra compression 8.5:1. Has to be what's holding me back. Blower is just about at max RPM according to an online calculator.

I'm not sure what fuel you're using but if that's on pump gas those numbers are pretty good. I was under the impression that was on e85.
