There are a couple of guys running it. What do you want to know?

+1 on above.

There are people running it, but some important things to consider to its specific application. You'll need to tell us what specific questions on it you want to know.

Well can it be ran on a NA LT1? Just curious..

Can it? Yes. Would it give you any marginal benefits? No.

E85, meth injection, or race gas are all essentially doing the same thing. Increasing your octane level to keep you away from detonation.

On NA cars IAT's are not high enough to warrant any of these things (99.9% of the time).

Boosted cars are ones with much hotter IAT's and the benefits of running e85, race gas, or meth injection are being able to safely run more timing and boost safely (yielding more power from the boost and or timing).

There was a recent thread of a guy who wanted to know if running meth injection on his NA car would show any benefits even if he upped his timing. Myself and a few others told him it shouldn't. He did it to see for himself and had it re-dyno tuned. Sure enough, there was little to no gains.

Its really the same as putting premium (93 octane) in a car that was meant to run 87 octane. Its not going to give you any more power or benefits unless its setup for it.

People like e85 because its cheap (so is methanol) compared to race gas. (Even though if you run it the mileage you'll get is s much worse that it comes out to about the same as running premium). E85 is also corrosive, so anyone going this route will need to have a fuel system that is e85 friendly, and will also need to be tuned for it afterwards.

Hopefully this gives a general break down for New Orleans, the OP, and anyone else reading the thread who is curious.

Crank the SCR up and get the benefits of E85, works for NA cars.

911,
You are actually wrong about benefits of switching. Yes there are benefits of switching, the heating value of E85 is higher than ISO-octane fuel like our 91-93 octane gasoline. Thus just switching nets you a gain in power. Now there are also other gains to be had because of switching to this type of fuel. Now to be fair, you can switch but you have to evaluate your reason to switch and your ability to have plentiful access to this alternate fuel source. There are many positives to switching as well as negatives.

I've been running it for 6 years, first on my bolt on engine, then mild heads cam, now on a purpose built 13.5:1 385ci. I run much cooler engine temps on E85, even with the stock 185* stat. As stated before, much more gains are to be had on a boosted setup, but an NA engine with high compression can gain from it as well.

The heating value? Explain this please. If you mean cooler IAT's then yes, but then you'd be agreeing with me since that's essentially what I said. But cooler IAT's on their own will not net more power that I am aware of. If I am wrong on this, please feel free to show evidence otherwise, because I would like to learn.

As I said it won't help in 99.9% of cars, it would seem yours is the 0.1% I left the margin for (a very high CR NA car).

If your CR was high enough were normal premium would give you detonation, I could see and agree that running race gas, meth injection, or in your case e85 would give you gains (or to be more specific, keep you away from detonation, so your setup could make the gains safely).

But realistically, for an average H/C/I car, I guess I don't see how you could gain anything from e85. Does someone have proof of this (as in a H/C/I car that was tuned on pump gas, then tuned again with the same setup on e85)? If so, I would be interested in seeing it.

You can crank timing if you want to compare a regular NA setup on E85, and can lower EGT/ECT as well.

CALL911

This was the same thinking the guy did with the thread I mentioned who did meth injection on his NA setup. But in the end he didn't gain anything significant and had dyno comparisons to show it. Definitely not worth the expense of making the swap to meth injection or e85.

I didnt know CALL911 was using E85... oh.

iTrader: (17)

? Nope. Not in my Z.

I may use it in my Formula.

What do you know about E85, leave this to the experts.

They picked up some decent power on a motor made for gas...

Yes they did. 19 to the wheels is a decent gain. Thanks for posting up a thread with some proof that power can be made.
