well from what ive read with the e85 gas is its a double edged sword: it has 104-108 octane from the e85 stuff, but it has a different consistancy/density so it might not be compatable with the current fuel solonoid plungers or something along those lines. im guessing if you plan on running e85 id use a dry kit to eliminate the posibility of the fuel noid failing, untill more solid results come out (or any!) there have been a few tests ive read of from boosted cars- some ford magazine had a twin turbo stang they built and supposedly maxed out at 700rwhp but they retuned the car with e85 and gained another solid 75rwhp. i predict in the short term turbo cars and dry kits will become popular. maybe robert was on to something with his triple stage dry kit on that z06 haha

Actually they are calling the fuel we run now E10.
There is tunning need to satisfy the E85 needs if you want to run your current car on it. Unless it is a Flex fuel car with the proper sensers to tell the mix of gas and Eth. you will have to run dedicated to one or the other.
I am planning on converting when it gets here and carrying a spare tune for out of town runs. The TT Truck will run it only and nothing else. I plan on running 14Psi on 9:1 SBC 355. Should be a great fuel for my tow rig. It also burns cooler and detonates less when tuned correctly

only true downside of it is it will get worse mpg due to it's potential energy being less per gallon or some junk, funny thing is gm is putting thier e85 tune on everything cuz the way they rate mpg is the regular gasoline # plus the e85 number but use only 15% of it due to it being 15% gasoline and avergae that out...tahoe gets 33mpg in the city hahaha

I did a lot of research on this and it is amazing how much water is used to produce this! Trust me, E-85 is just not the answer.If we keep producing this stuff we would start running out our water supply. Then guess what? Water would start being worth gold and we would be charged way more. Vicious cycle!

I wouldnt spray on E85 yet until you did some good calculating. E85 is higher octane, but the energy available is less than per an equal amount of gasoline. Basicly what that means is that your A/F ratio would be a whole different ball game, as the stoichiometric efficiency ratio for Eth. is alot lower than for gasoline. On power adder gasoline cars you shoot for an A/F around 12:1 which would be equal to about 6.5:1 with ethanol.
Translation: you need ALOT more ethanol than gasoline and your jetting would have to be changed to compensate for it on the fuel side by about 30%.
Ethanol also burns much colder than gasoline as well as being much higher octane, so it should prove to be an incredible anti-knock additive, but since the cooling effect of nitrous oxide already adds that effect, Boosted cars would benefit much more from the fuel than nitrous cars. Someone also mentioned a possible problem with solenoids because of the extra corrosive nature of Ethanol compared to gasoline (although less corrosive than methanol). Ethanol is a form of alcohol. To remedy the problems that might be caused to fuel solenoids, you would simply need to use an alcohol fuel solenoid in your system.
Overview: it will work. Look at all the alch. cars out there that use nitrous oxide, but I dont think it will have much of a benefit at this point over standard gasoline, as it requires about 30% more fuel and the benefits of it being a colder-burning fuel will probably be negated by the cooling effect of the nitrous oxide itself. Make sure you calculate for the extra fuel you need. It might also be interesting to actually sit down and see if Ethanol is cheaper than just standard 100 or 105 octane race gas, considering that it will be used at an increased rate of about 30%.
I should also note that just like alch. motors you can get away with alot more C.R. and initial timing on ethanol as well. If you have the fuel system to support it, ultimatly more power is available by the insane cylinder pressures you can create with the high compression ratios and advanced spark.

Looks very promising, and with tuners like Ellis on top of the tune issue, we will surely see this happen soon. I think it was brazil using e85 is now 100% self supporting and giving their money to their own farmers rather than the ragheads. Spraying, like hennytime said, at this point is not an option with e85. Only a couple companys currently are working on the e10 swelling plunger issue. However, it's just a matter of time before the noids will be compatable. Lets get this ball rolling and stick some sand where it doesn't see light concerning the mid east rag heads.

There are LOTS of reasons that E85 has to be developed more. Yes the combustion properties are different from pure gas. There are other things to consider like the lubricating properties, the corrosive properties when it come to certain metal and rubber parts, etc. There are issues with water contamination. I'd stay away from E85 and solenoids that are not engineered for that use by the manufacturer.
