like danny said, still not worth it.

93 is fine for daily driven, if you really want to run 700whp on the street, god help you. The only cars i think that should probably look into E85 would be 700-800whp supras that are street driven.

for us honda guys, we can achieve 500-550 on pump gas, and thats more than enough.

If your a drag race only car, then i could see testing different fuels to get power numbers. but then again, that takes a big budget. Something not everyone has.

i say keep it simple, run 118 an call it a day.
