I use e85 in my car, works great. With the cooling properties, high octane, and low cost, it sounds perfect for boosted motors. The only real maintenance issues I have is you can't let the car sit for weeks on end (the fuel absorbs water out of the air quickly). On my carbs, the little check valve under the squirters (looks like a silver bullet) gets stuck if it sits too long...its an easy fix, just remove the squirter and shoot a little WD-40 in there...no biggie.
