A: E85 is a renewable fuel source that is also environmentally friendly. Its performance is comparable to race gas at a fraction of the cost. Your engine will run cooler and your ETs will be less affected by atmospheric changes. E85 is not corrosive like methanol and does not leave carbon deposits like gas so maintenance is reduced across the board. With the proper tune-up your oil stays looking like new." "Q: Don’t I have to replace all the “rubber” in my fuel system so it want be eaten up by the alcohol in E85? A: NO!!! We started out on this journey with a complete gasoline system. We upped the flow 30% to compensate for the lower heat energy output of ethanol and left everything else the same just to see the effects. We switched to E85 at the end of the 2006 racing season and to date we have found zero deterioration or corrosion anywhere in our fuel system. We leave it in the system all the time. We don’t drain anything between races or use any type of fuel lube." "Q: What type of performance can I expect from making the switch to E85? A: It has been our experience that E85 with its 105 octane rating and high tolerance to detonation is superior to premium pump gas and equal to and in most cases better than 110 octane race gas. We picked up a tenth of a second and 2 to 3 miles per hour in the eighth mile after switching to E85 from 110 race gas and our engine runs 20 degrees cooler." Tuning with E85 nets big power!

According to Wiki's Nitromethane, "Gasoline provides about 42–44 MJ/kg whereas nitromethane provides only 11.3 MJ/kg."

Oh, by the way, do you know anything about the heat energy of nitromethane? As I recall it is even lower than ethanol, but can sure produce a lot of power.
