E85????

[Alerojester]

i was reading through Super Street while waiting for the wife to get off work, and read an artical about how E85 is the new 105, and beings its cheaper then regular gas i began wondering what it would take to convert from normal gas to E85?? i haven't done too much research on it as of yet just wanted to throw it out there on here and see if anyone else has thought about the conversion......

Sure it's cheaper, but fuel economy goes wayyyy down too.

[kwhauck]

if you have a stock motor, you don't need it, but yes it is cheap race gas, it is readily available at almost every gas station in the midwest, and I fully intend on running e85 full time with my built motor.

I'm pretty sure E85 in a motor that's not built for it will eat thru gaskets like a fat kid in a candy store

[Alerojester]

yeah that's what i was thinking too redog, and i was planning on building a turbo motor with the one that's in my car at this very moment. I am planning on buying another engine so the car will run again. and i will have something i can tinker with in my free time while it snows this winter

/\ I don't think that is true. I have heard that it is corrosive to rubber so eventually it will eat through fuel lines but I am pretty sure that is rumor as well. Just will require the appropriate mods to need it, larger injectors since you need to burn more of it at once, and a tune.

[robalero]

you need larger injectors and tuning it, I know of people who have done it to older aurora's ( well one person who claims he did anyways no real proof ) and thats what he said he had done other then that I really don't have any idea of how to do it and id just stick with regular gas since its not that bad of a price right now anyways

[Alerojester]

true true but E85 is $1.82/gallon

E85- just say no!

I tried it and it didnt work well... The car started acting up.

I tried a 50/50 mix seemed ok. Second time I filled up from E with it. Never again!

^You tuned it right? With bigger injectors? Lol. The AFR for E85 is like 9.7:1 compared to gasoline's 14.7:1..

[Alerojester]

ok 91 it is then

When Bbody.org was still around there was a guy in Brazil with a 1978 Buick LaSaber and that's all they offer. It worked out to be something like .80 cents a gallon in American money.

Well his car ran like shit, wouldn't go above 60, and had a hard start.

I'm sure if you tune and rebuild with E85 freindly gaskets, the engine wouldn't really know the difference. However the closest E85 station to Philly is between Harrisburg and Pittsburg, way off the turnpike, in the backwater sticks somewhere

E85 isn't worth it for a daily driver. The consumption rate offsets and overtakes the lower price.

When I was at the track in Denver back in August, there was a guy named Zach out there, who runs a stock Grand Prix, with the Gen III M90. He was running E85 with everything else basically stock except the injectors, CAI, pulley change, and DHP tuning. He was running 13.7's all night to my 14.0's on that occasion, and wasn't even doing complete cool-downs. I believe that could get high 12's at a lower track.

I have not seen him since to find out longer term effects on the car, but that was pretty impressive. Zach said he was president of Rocky Mountain Club Grand Prix ( I think that's the name) , but I don't have a link to it.

I have also run straight E85 a time or two, and the car ran fine, maybe a little cooler, and cleaner. But I did not have larger injectors in long enough to power test it , or get a good tune on it.

Most later model cars example, n-bodies will be fine for the most part.

e85 is the new c16. In some states, running race fuel is 100% illegal. E85 is more or less 105 octane. Your car needs more of it to run right.

On boosted motors it gives the effect of 105octane, along w/ the cooling effects of alcohol. It's like crack on a car when a car is setup properly fueling wise.

Local shop here in Vegas, which coincidentally I have frequented many many many times. Has done e85 conversions on datsuns, mitsubishis, hondas, nissans... quite a few vehicles. Even the old ass datsuns, w/ new fuel lines ran like a champ when properly tuned.

It's not cost prohibitive, but fuel economy does go down. However if you're wanting to make some good power on a boosted setup, it's a an absolutely delightful option when it is accessible.

Word of warning again. You can't just dump it into your gas tank and think you're going to be aokay. You absolutely 100% need to retune the car for it.

[BlackJack]

I'd love to know how they run the tuning on that flex fuel shit. Just dump whatever you feel like in it, and it runs just fine.

+1 On what spy said, its perfectly safe on stock fuel systems and cars designed to run on gasoline. All it requires is a tune, because of its resistance to burn ethanol has best been used as an octave booster. Even back in the early 1900s it was primarily used as an alternative fuel.... until people abused it by drinking it.

[Ryan from Ohio]

If your car is not made for use with it then dont use it.

Pretty simple.

Go ahead and try when your on E next time.

Isnt this the fuel that will gel stuff up and clog injectors???
