E85 on both N/A and boosted cars is more for safety because it's a higher octane fuel (E85 is around 110 equivalent IIRC). But you will also drop your MPG down about 25-30% over 93.

This is what i think i was referring to, ford stock to e85 tuned... not 93 tune to e85 tuned.

I don't have a good before and after dyno on the same dyno, but my car picked up 9 mph in the 1/4 by going to E85 in some 50 degree air vs 93+Torco in 80 degree air. That's HUGE!

That also had a lot to do with the temp outside as well. I always ran faster in colder weather if I hooked.
