From http://en.wikipedia.org/wiki/E85
"E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts. The Renewable Fuels Foundation states in its Changes in Gasoline IV manual, "There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual-octane engine tests." [6]"
Also e85 is be much less fuel efficient as it takes more to get the correct air/fuel ratios.
You need to be aware also it is very corrosive, special seals are required or materials for your fuels system and due to the increase fuel usage a larger fuel pump.
I thought about going this way but did not also not available most places as mentioned above.

Also be aware that E85 burns %30 more fuel to make the same combustion power as gasoline. So your gas mileage will be %30 worse. I have a buddy running a 14:1 compression sbc on E85. It works good for high compression engines.
You can do it nova but you will need more fuel pump and a e85 carb. I'd suggest asking on yellowbullet about e85 carbs they have a lot more info over there.
You can also order it in 55 gallon drums for a lot cheaper than out the pump. Most 55 gallon drum purchases work out to around 2-2.50 a gallon. Since your not street driving it you might be able to do it.

The 30% volume is somewhat not true. The higher compression to a point the more efficient the engine will run. Don' t ask me how but I was getting 11 mpg in my 13.1 496 that I drove over 200 miles a week. I was getting around 13 on gas so I didn't lose much. What is awesome about the fuel is you can run high compression and the car will run extremely cool all day. Even on a 100 degree day in traffic my car never saw a 190 degrees. If anyone is interested I am going to a twin turbo LS1 and I do have the ProSystems E85 carb that I was running for sale. It ran great on both the street and the track. 6.30's in the 1/8th after driving a couple hundred miles all day with my kids.
If you have a station 27 miles away, then bring a couple 55 gallon drums with you and when the price is cheap then buy it up. That was what we did. This is my 4th year running the fuel. I buy it straight from the pump. I am also going to run it on my LS1 twin turbo with NO INTERCOOLER! Awesome fuel! 105 octane!

I called a couple of guys about e85. One guy out of winston salem sold a racing fuel called ignite. He wanted 7.20 a gal. Whats the difference, why so exspensive? The e85 at the gas station was 3.14 a gal. WHATS THE SHELF LIFE WITH E85?
i love E85, i just switched to a blow thru setup after maxing 160lb injectors. this fuel is very hard to detonate and i have ran it as high at 25psi so far with a 12.5a/f and 22 degree timing. plugs looked hot but safe. hopefully in december il lhave my blowthu running looking to make 1500rwhp. 424cu lsx, 106mm turbo, csu 850 carb
