max boost for 91 octane and daily driving?
What the maximum boost you can run SAFETLY AND RELIABLY on 91 octane? In the interest of engine longivity, I was originally going to boost only 13 psi on the street (with 91 octane) but I'm reading about people on the forum boosting 15+ psi on pump gas with daily cruising. Just curious as to what type of boost levels people are running and their inputs

I am running at least 1 bar on 91. I have been mixing with the trick 101 and running 17-20psi with no problems. Slowly I have been weening my car off the 101 and seeing what happens. Right now I have about a 60/40 mix of 91 and 101 and everything is ok. That is a no less than 11.5:1 A/F, timing at peak torque at 15psi is 12deg with a 10deg split.
So far, so good...
