i dont mean to jack the thread but what about using E85 as an octane booster E85 itself is 105 octane

if mixed 50/50 with with 93 octane it comes out to be about 99 octane i have heard it is corrosive and hard on metal fuel tanks along with rubber but they are already set up to have to deal with atleast 10% of ethonal in most fuels already so my question is would it be safe to run as an octane booster as well?

In short, no. E85 requires a much richer concentration. Something like 9.5:1 instead of 14.7:1. Mixing it with gasoline effectively leans out your AFR thus negating any gains in octane.

And possibly require bigger injectors, fuel rails, lines, pumps, and its tsill yet to be established that running high concentrations of ethanol wont dry out seals. Granted, you could probably get by with simply tuning if you only wanted to bump up the octane a couple points. Toluene / Xylene, however, wont require any tweaking of a tune.

That being said, if ethanol pumps ever become commonplace in the northeast, Ill be one of the first to do the conversion.

Watch out for fuel system corrosion and water contamination.
