e85

It definitely resists detonation.
Pre-ignition is another issue and I would sneak up on optimum timing , but I have heard of higher compression numbers working too.
Keep us posted on how it works for you......I'm still a month or so from making laps and don't have a gasoline baseline to compare to.
But I think I am on the right track.

Yes I'll definitely post up how it works out. I'd like to run gas for a while to get a feel of the car when it's all back together and then try to compare it to E85 after the swap. But I'd really just like to get it done now while I'm already rebuilding things. If I go ahead and swap now, I won't really have a baseline comparison to gas. If I swap later, I'll have to have the car put up for a few weeks probably. There's things I don't like about either option! :-({|=
