Some babbling on about E85
So i have been thinking about using E85 in a project for awhile now and the trigger pull will be based on what my orders will have living near. If E85 abounds, then i might as well. If its scarce it would prove difficult for now.
Anyway, im thinking about building an engine FOR e85 use only. Something in the manner where 93 octane would not suffice due to higher compression. In regards to this, i would also design the intake, in my case, the head and other factors for the differences in how E85 burns. Now as for rotary engines, im not at the point where i can be bothered with it since i dont plan on running forced induction any time soon and there is no good solution for high compression rotors. But for the DSM rallycross car, i could run very high compression, and build the car to be optimized solely for E85. Would be worthwhile to document the effects of certain things. That and give me an excuse to spend time and money in the pursuit useless projects.

The quest for more torque

If you have the injectors to run it, E85 should give you better torque than pump gas (you will need a lot more of it). E85 actually contains oxygen in the fuel, requiring less air per unit fuel, and allowing more energy to be released per engine revolution.
Obviously, the E85 advantage for a rotary is mostly in the turbocharged realm, as even a 9.7:1 rotary likes 87 octane just fine.
