E-85

Anyone know the air/fuel ratio of E-85 ?

I think this is what you are asking for....

Thanks, that answered my question as well a giving me a lot more information. Like why you should never try E-85 in an unconverted engine.

Well, some engines are a lot more tolerant of it than others, especially if you're only using it part of the time (like for track events, but switching back to gas the rest of the time). What are you wanting to convert? Don't let the big bad wiki scare you too much. If Ford can make cars run on E85, you can too!

I'm not rying to convert anything, just a discussion with friends. Any engine can be converted to run on E-85. What car/engine have you run on the track with E-85 without some sort of conversion.

Car craft is one mag that does a lot with e85. Of coarse big block with 3 speed autos in vehichles that have worse aerodynamics than a brick have E36 M3 for milage anyway, so they wont notice the extra fuel use

OTOH, when they did a dyno shoot out, every car ran E85, it can be like poor mans 100 octane, you just burn more.

Turbo/supercharged engines work the best on E-85. People get carried away with the higher octane rating,they forget that it takes considerably more of it.

there are a few guys with 240sxs that just swap out the stock 270cc injectors for the stock sr20det ones witch are 330cc with no problems now if you tune it for e85 you can get some mileage back and advance the timing for some more power

In the end that extra bit of e 85 you burn will cost less than if you went out a got real racing fuel

I understand the theory behind that, but i wonder how much of it is blown out of proportion.

If you look around on the DSM forums, you'll see that there are multiple people on there that have been E85 for years on their uncoverted cars, and have had ZERO problems.

I know of at least two 1988 Celica AllTracs that are running E85 with nothing changed, except for the fact that they gained another 2-3psi that they could run without pulling timing. :)

Would i try it? Yeah.... maybe. But i like the nifty stainless steel lines anyways, so it just gives me an excuse for more "bling blang."
