I was wondering what the max timing you guys are seeing in data logs running E85. I know most 93 octane tunes are around 28* + or - a degree. Naturally Aspirated results only, thanks. (edited)

I'd like to hear why it picks up that much power without adjusting spark. Is it just the cooling capacity of the fuel?I have yet to do strait back to back on bolt on cars but on the last CPR single turbo car I tuned, we picked up 50rwhp with no added spark with me only changing the tune for the e85.
It was my car mastwolf is talking about, E85 is awesome. Like he said 50hp increase with no timing adjustments. If I remember right it was only at 12 degrees, and 7lbs on that pull.
And soooo... We see the cooling effect of e85 on a car using compressed air being forced into each cylinder...And soooo.... where did the power come from? Was it rich before and was leaned out on the E85? Knocking/pulling timing before and the E85 got rid of it?
Unless i'm missing something, it's not some magic fuel that creates hp out of thin air...
E85 has a sort of a chemical intercooler effect so it will create power out of thin air by cooling the intake air charge significantly. The extra fuel needed when compared to 93 also helps to cool the intake charge further more. This is all on fi ofcourse.And soooo.... where did the power come from?

I appreciate all info on the Forced Induction side and would have already converted if I was boosted but I am only curious about NA results and mainly the amount of timing because my local 93 octane is better than most allowing me to run 30* of timing with zero knock. If switching to E85 is only going to allow me to see 31* of timing I don't think it's worth it for me to switch however if I could possibly bump timing to 33-34* it might just be worth it.
