Default Using E85 as a substitute to race gas on high compression/high boost motors

Knowing that E85 has approximately 83,000 BTU/Gal and Gasoline having approximately 114,132 BTU/Gal. A person could take advantage of E85 at a local gas stations to street drive a motor that is designed for 100+ octane gasoline. I've researched E85 and have found that it's octane rating range from 100-110.

There will inheritantly be a HP loss when using E85, but the benefit from the easier accessability may be just what's needed.

Would it be economically feasible to build a higher compression/high boost motor for the track that could be street driven on E85?

stoich is lower, so you would need different injectors able to handle the crazy amount of fuel needed.

Other than that and the proper fuel system (pump, lines, regulator). I think it could be done rather cheaply.
