I bet there isn't any more power with E-85 on a naturally aspirated engine than 93 and maybe 91 octanes.
Be careful betting too much moolah!
Octane requirement is radically platform dependent and can even vary from car to car depending on carbon build up and many other factors. Lots of cars can have very different compression due to cam timing and cylinder head design, it's not just forced induction that likes slow burn fuel!
If you can flow enough fuel and get the timing out far enough, as most cars injectors are too small and timing is fixed in a narrow rage, MANY naturally aspirated cars could have more power on E85.
