E85 is great, and you can make serious power, but to make the same energy as gasoline, it takes more E85 ( i forget the number, but its more than you think) so the cost effectiveness in a tuned or performance car is worse per gallon than good ol' gas. Couple that with a thirsty rotary, and gasoline is the best choice. E85 generates 20% less energy than gasoline, so you would have to upgrade your fuel system on a modified car to make up the difference.
