So riddle me this Batman...

besides the mileage factor which I believe is generally accepted to be less than typical gasoline...

If you run E85 does the engine make more horsepower? What is the octane of E85 (I was told in Texas it was 105 - maybe it's like everything in Texas - bigger)? Does an ethanol Octane rating equate to an octane rating for typical gasoline? Would you get more horsepower like you do with 87 vs 91 vs 93 gasoline if the engine were setup to continue to boost higher if the knock sensor was happy?

If the engine does produce more horsepower, and mileage is not my goal, would running E85 be a good thing to do, and are there any other side effects, aka do I have to do any ajustments to the vehicle to avoid issues?

Let's pick cars like a 1987 900T with LH2.2, a 1990 900T with LH2.4,

and a 1996 9000T Aero that specifies premium.
