Eric, I agree that E85 is a good alternative. I would be curious to see if the higher octane would allow you to run enough boost to make up for the lack of energy in the E85. It does come out similar though, because stoicheometric for ethanol is 9:1 vs. 14.7:1 for gas. So you burn 66% more ethanol to make the same amount of power in gas.

The other cool thing is that ethanol has a very high latent heat of vaporization (it will run much cooler). This should allow for more timing and to make more power. I should have big enough injectors to try and do this on pump (950's). I might try a 50/50 mix and go from there.
