I've been doingsome reading on E85, but all the sites I've looked at seem to want to pimp the FFVs. if i run E85 in my car, would there be any damage? what's the story?

Without any way to "tune" it, it's not going to run very well at all.

Most of the conversions the turbo guys are doing are requiring injectors that are 25-30% larger.

You can't just pull up to the pump and fill your non-flex-fuel car with E85.

There has been alot of discussion on turboford.org and a few guys have converted theirs over, but it's not going to work with stock electronics....

Yes, it will damage your car if you run E85. It is 85% ethanol (alcohol) and 15% gasoline. You need to beef up the fuel system and injectors and run a programmable ECU if you want to use the stuff.

Edit: dammit, you beat me

ok, thanks! it just seems very tempting with it being cheaper

also no one's mentioned why alcohol-fueled cars use silicone fuel-handling materials and gasoline cars use all rubber materials.

alcohol = dries out/wears down quickly/whatever rubber
gasoline = bascially eats away at silicone.

youd have to essentially rip out most of your fuel delivery system, you injectors' gaskets have to be changed, etc....

yeah, sucks. i hope that with time that will be less costly and there will be "kits" and specialty "conversion" parts for whatever manufacturer and platform/engine/chassis you got. maybe not specific to the model but maybe like for fox cars, or for any ford with a 302 EFI etc....

though honestly what i would LOVE to have right now is a diesel. im be runnin' around to all the fast food joints grabbin up veggie oil. if i had a little more money id seriously do that too, with like an old 80s Benz or some cheap diesel, so if the veggie stuff ruined it, so what, not like im out $5000. id make a custom ultra-powerful fuel tank heater to keep it real warm and thin and everything, ill bet it wouldnt even get ruined!

No one has aderessed it, as the guys who are running E85 haven't seen any problems. Most of the EFI cars don't use rubber, and haven't in a while..

Not one of the turboford guys who are running it (perhaps 6?) changed anything but their injector sizing and the programming.

The biggest problem I see is availability. There are a grand total of two stations in Columbus selling E85. Both are on the opposite side of town from me. I'd have to drive 20 miles just to fill up.

NO WAY!!!! That's pretty awesome. I thought FFV's included a completely different delivery system. Though it sounds like changing the air fuel ratio isnt child's play the whole changeover to e85 isnt nearly as bad as i once thought.

Pretty cool.

There's a lot of stories and whatnot of people "claiming" that E85 ate up fuel lines, pumps, and stuff.
I say PROVE IT.
I ran some stuff in my truck a coupla summers ago...was more than 85% alkie, didn't hurt anything.
I DID have to replace a FPR later on, but that was bad BEFORE the alkie was ever used.

The FFV stuff can detect the E85 fuel, and the EEC compensates for it.
Ideally, a higher compression engine would be better suited for a strictly performance gain, as alcohol burns cooler than gas.
But then, we ALL know that more compression means more power etc etc....

would E85 work in the older 70's carburated cars?

That;s where you'll run into alot more rubber components...... so that would be an issue.

Aside from that, upsizing the fueling (jets, etc)...its should be the same...

Add a Little 2 stroke oil to it,

I apologize for not reading the linked thread...but the conlcusion I have made is that the current price of E85 doesn't outweight the mpg decrease you see with it. Anybody have prices that makes it cheaper to run E85.

If you have a turbo system, you can run more timing...but it still costs more gaswise. However, sometimes one wants power more than money.
