e85

i remember seeing a thread about it but cant find it now...how are we switching/converting to e85? is it all in the tune or are there other things to go along with it?
 


Bigger injectors...I'd get a new fuel pump but I dont think it is required...just gotta get all the old gas out of your system LOL

Running E85 is like what...116 octane or something crazy like that? Not really sure on E85...but form what I hear it is pretty awesome.
 
bigger injectors and a tune. you also need to swap your fuel filter a couple times because it will clean out your gas tank.

e85 is running about 105 octane all the time, so it has big benefits over 93. i was damn close to running it but i ran out of steam with the car. would have made for a hell of a rocker car.
 
What # injectors would you suggest for like a 3.0 on e-85 Bio? I have thought about doing it for a while. E-85 not the pulley.
 
i had 65# injectors. most people say that if youre not going much more than a 3.4 setup or so then youll be good with 42.5# injectors. i was planning on going big. i was going to run the smallest pulley possible on just above stock timing which i was hoping with meth/e85 was going to be in the 2.8 area.
 


it dose help if you not getting on it all the time. but when you do get on it you use more gas, and e85 is 210 a gallon. look and see what it would be to get 105 octane. no 210 a gallon.
 


E85 has about 20-25% less energy as compared to normal gasoline. The benefits are obviously the octane, burns much slower. Also, not really right now but as more and more demand for it increases, the price should drop. The problem is right now not many people running it, so the price is around $2.30. You can buy gas right now for that, and when you figure you need more e85 to get the same amount as gasoline, doesnt make sense cost wise right now.
 
Where I live in Colorado, E85 is only a penny cheaper (2.09 E85 vs 2.10 87 vs 2.30 91). The folks I've talked to says it burns about 1/3 quicker than regular gas... which is a 1/3 decrease in fuel economy! (really sucks)

But, if you want to use it at the track (or to fool the emissions station), I've also heard you can mix a little in your tank and not really do any damage... don't quote me on that one though.

Octane rating is determined by the rate the fuel burns, the slower the burn, higher the octane, so that would be incorrect. I think your friend is referring to the fact that you get less mpg with e85, which i already stated above. As far as mixing e85 with normal gas, you could, but your octane rating wont raise that much, in fact, every gas in the U.S. now has 10% ethanol in it anyways.

The problems with converting to e85 are:
1. You need to upgrade injectors, get a tune.
2. Make sure your fuel system can handle the corrosive properties of the e85, it hates aluminum, something to keep in mind. Im not sure how our fuel systems respond, havent really looked into it.

I was going to mention the fuel system thing and aluminum parts. I think most of the "hard" fuel lines would become corroded when running e85. I think those would also have to be upgraded to stainless steel.
 


Sorry to thread hijack, but here's a question I haven't seen-...

I was thinking of going intercooled on my GEN V setup, wanting to run a 3.0 pulley. Right now I have 0 KR WITH 19* timing on a 3.4. It costS about $800-1000 for the i/c setup.

Would I make just as much power on my 3.0 pulley by just getting injectors and tuning with e85 for just the cost of the injectors??

oh my god i hate you.

E85 IS NOT CORROSIVE AND ANYONE THAT SAYS THIS OR TELLS YOU THIS IS A COMPLETE ****ING MORON. ALL SEALS AND FUEL LINES HAVE BEEN PREPPED FOR RUNNING ETHANOL FOR YEARS!! WHY DO YOU THINK CARS DONT JUST FALL APART FROM RUNNING THE "UP TO 10% ETHANOL" IN REGULAR GAS?! TAKE A CHEMISTRY CLASS.

do not start rumors about this. you need two things to run e85:

1) bigger injectors
2) a tune to make those bigger injectors run right

and possibly a third:

3) bigger fuel pump if you intend on trying to go for a BIG build

it really depends. im not sure that e85 would soak up the effects that an intercooler would produce.

Fine, you win. The fact is that e85 is more corrosive than gasoline but its not a considerable amount to do damage.
