cuz AGP says above 22psi you should have race gas in with the SCT tunes... so with E85 being 105 oct and being half the price or more of race gas this would be a huge money savings
My comment was sarcastic...it is a great idea...I have brought it up in a past conversation with Ben. The octane is higher with E85 over pump gas, however you need to run it 'richer' than regular pump gas. Im sure timing is different as well. Not sure if the FlexFuel vehicles out there have special fuel lines...E85 might 'eat' away at the lines differently than pump gas....that is just a thought....i dont even know if it is true or not.

theres a number of threads in the fuel section on this topic, and a ton of knowledge on DSM and EVO forums about E85.
You have to run about 30% more fuel delivery, because it burns stoic at about 9:1 (vs. 14.7:1 gasoline).
however, since its basically 105 octane you can run a shit ton more timing and boost.
how much is race gas in your area? Here, our 100 octane unleaded pump is $5.99 / gal. I was seeing E85 prices in the high $3 range, about $3.75 or so...do a little math (3.75 * 1.30) = about $4.88 / gal. Better price than 100, and a better fuel too.
in duluth minnesota theres one gas station that sells 110, it was 6.50 per gallon last summer... havent been there yet this year but im sure its more and e85 is right around 3.65
You're forgetting the cost involved with an extra fuel pump, fuel lines, 1000+ cc injectors, peak hold box, etc. THere's a little more involved than just throwing some corn gas in a car and expecting 105 octane worth of fuel.

depends on the fuel requirement. there's guys in the evo world running single walbro 255's and big injectors on smaller sized turbos / stock turbos.
you can get plug and play, larger than 750cc injectors for the SRT-4.
on most people's DTEC type tunes for 750cc's on a SRT-4 they have about -30% correction. I wonder what that same car would do w/o any correction on E85. If I had the resources, I'd like to try this fuel. But my car can't be down for extended periods of time right now, and I dont have the SCT PRP.

And if I wanted to make 375-400whp on my evo, I would just tune it right on 91 octance.

I am aware, and they work so wonderfully.

With zero correction, you'd be able to run around 15psi max before you max out the map sensor voltage. So 15psi on any turbo is not going to be any real power.
I'm not trying to argue. I know all the benefits of E85, but for most of the world it's certainly not worth it.

I'm not trying to argue either. It takes a hefty fuel system to make real power on E85.
It just seems like such a taboo subject in the SRT-4 community.
