^^^ Going from E70 to E85 left me over a point lean on the wideband at idle through WOT, definately not a good thing...

 

what you buy at the pump in a cold climate it's not e85 it's more like e75 ethanol is hard to start when it's cold.
just mix 85% ethanol 13% c16 / I think specific gravity shoud be 768 ?

 

yes there is a difference in E85 during the colder months, but trust me , we live in colorado where the ethanol can be anywhere from e70 to e85 and we have never had a problem. guys out here including us have been using it for years.
if you dont tune your own car then it may be a problem because depending on the weather where you live it may be as low as E70, but for the guys that tune their own cars or retune them often everytime they go to the track or even know how to make minor fuel changes to their tune, there is really no reason not to use this fuel. you will know the quality of the mixture immediately by keeping an eye on the wideband. make changes to adjust for that batch of fuel. simple as that. i think its worth the extra effort considering its about $2.19 at the pump for us out here and we make more power on it than C16 which is nowhere near 2 bucks a gallon lol. If its a fast car in colorado there is a 95% chance its on E85, but thats also because its way more available at pumps out here than most of the country.
thankfully we are able to run E85 much leaner than pump gas as well so although it requires more fuel to run E85, we still manage to get great gas mileage due to how lean we can run daily driving loads.

 

would I have to change anything in my fuel setup to run this?

are all injectors able to run this without issue?

 

nope, I do recommend using fuel filters with stainless elements but other than that nothing additional is required.

 

Actually, it is oxygenated...but it doesnt contain harmful MTBE. By chemical compound Ethanol is C2-H5-OH

 

I dont know who told Schister that E85 is non-oxygenated but the source was definately wrong.

 

Yeah...excuse that comment. I know the chemical formula of EtOH (as written it shows the hydroxyl -OH group) since i have taken and am currently taking Organic Chemistry. It is an oxygen-containing fuel, there's no doubt there. I was under the impression that the other fuels were heavily laden with oxygen containing hydrocarbons. I'm actually quite embarassed of my comment...lol. An oxygenated compound by definition means it contains oxygen, in this case in a hydroxyl (or alcohol) substituent.

Does anyone have a link that actually shows the main components of various race gases? I've been looking, but haven't been able to find anything...i want to learn more about them and to see if they are diol, triol, tetrol, etc molecules.

Again...ignore my previous comment

That source was me...as explained above, i was wrong in my assessment. It was a reply without much thought put into it...

 

If I were to go get a barrel of this, how long would it still be good

 

This question is for the people who have been using E85 on their Turbo Street cars:

What type of oil are you using and how often do you have to change it?? Have you noticed the oil being broken down a lot faster?

 

i have been using castrol 15/30

change it about every 10 runs it doesnt look bad to me at this time, but it was recommended to me by my builder so i go with it. I also do the tranny fluid at the same time

 

so with e85 it takes 30% more fuel. which means u need bigger injectors and maybe another fuel pump. ex. if ur running 750cc injectors and want to go to e85 u should go to 1000cc's. a advantage of e85 is there is far less knock in the motor. also if ur running it in a street car it runs cooler so less over heating problems.
people are right and it is harder to start in colder weather.
i live in az where its not a cold as back east so we don't have to many problems with the consistency of the blend but from what i have read and seen, make sure to check the e85 to see what octane it is. should be 105-106. going from 106 octane to 99 octane means BOOM!! which isn't good.
Hope this helps a little.

 

Rockett Brand says 2 years from when opened

 

good to know

it would definetly be in my best intrest to look into this stuff.
I have to decide if my current fuel setup will allow me to get to my power goals with the E85

 

o and the person that was talking about his tunner never tunning e85, go to a tunner that has tunned on e85..

 

if a tuner can tune gas, he can tune e85, it takes nothing special. I was the first e85 car my tuner has tuned and we made more power and a better curve than ever. 850whp

 

Im running a dual walbro setup, with RC1000's

any ideas as to how much power I COULD make with the E85?

 

Anywhere from 475-550hp, depends on the dyno... the Injectors will be the limiting factor.

 

thats pretty low actually

 

hey guys i made 416 on 93 octane. If i switched to this would I see a major difference, considering my car is boosted.

 

we have made 622hp on that same injector and pump setup for a little while on the stock sleeves. didnt leave it at that power for long though. now its sleeved and we are on the same fuel system....ill let you know what we make but i would try to get some bigger injectors if you can so you dont run into the problem of not having enough injector. we are going to max the 1000's just out of curiosity but we will then be switching to bigger injectors for the rest of the season.

 

thanks for the heads up.

I was thinking about switching to a set of ID1000`s EVENTUALLY

 

if you are willing to spend the price for some great injectors like that, just get the ID 2000's. its worth the extra money. the 1k's are great injectors, but we ended up maxing a set out way sooner than we thought. save a bit more up and get the 2K's they are easy to make idle and are just as controllable as the 1k's but you have much more overhead.

 

one thing (or myth) that i have heard about e85 is that it will eat away rubber fuel lines since its oxygenated, is this fact or fiction? and yea its a bitch to get an e85 car to start in the butt *** cold

 

actually corodes metal lines and tanks.... not rubber oxygenating corodes metal lol but if im wrong please some one correct me
