I'm going to be running 11:1 on 8 pounds.
I've heard of guys running 11:1 on 10 pounds with stock internals on an S2000. Not sure if that was on race gas though.
In any case, just watch your Air Fuel Ratio, your intake temperature and every time you fill up, for the next half hour, listen for detonation/pinging carefully. If you hear any, don't push the car and immediately add in octane booster. You may have gotten bad fuel.
