The car's don't knock but they don't make any more power or go any faster. I have ssen them knock if you go below that. I try to target 13.0 on E and have run it all the way down to 12.3 or so to possibly take advantage of more timing. Pretty amazing that you are up to 36*.

Pray, I'm not sure if you were talking to me but I will point out that I use different types of "E85". I have posted this in other threads before. But the actual octane content of C85, E98, X98, FTW Purple are very different than the pump stuff. I am sure that you are aware of this. What have you found as the max power timing and AFR for some of the higher end race fuels? Also I don't know AFR so this is a genuine question. I use Lambda as I try many different fuels.
Edit: just re-read the thread. Seams you weren't addressing me. But I just want to keep this thread alive as nitrous builds are few and far between.
