E85

[Demon Coyote]

What do you mean by mixed in?

I think what he is saying is to cycle it out sometimes by using pump gas. Two of my buddies running E85 on their STI and EVO once in a while near empty our their tank and fill it with pump and run it on their pump tune for a little bit. Then they switch back to E85 again.

Really? I haven't seen that. E85 is clean. I've seen plenty of fuel filters, injectors, and engines after running it for tens of thousands of miles, and everything looks brand new.



This is a dumb comment.


Expect to make 20+ rw over 93 octane, and the benefits of knock resistance due to how cool it burns.

Um, do some searching for E85 gunk or black goo. Can't believe you've never seen reports of E85 destroying stuff.

And it's not totally a dumb comment IMO. E85 on an NA Coyote is only good for around 10 peak hp. There are bigger gains throughout the curve, but peak numbers only about 10ish over 93 pump gas. You're not getting 20+ Rwhp gains peak vs peak unless the previous tune sucked

So I guess maybe it's not worth it to some on an NA car because the risk outweighs the reward.

If you are willing to run it at all I can't imagine there would be a problem with mixing it. Pump gas as most gas stations is essentially E10 or E15. Its hard to find corn free gasoline these days unless you are on a boat dock. I'm guessing the reason people are asking about this is because ethanol potentially has more octane than gasoline, drop per drop? I say potentially because as far as I know, ethanol doesn't actually contain the hydrocarbon "octane" but this is all armchair net-wisdom so please don't take that as gospel. My opinion however is that its not worth it for a daily driver to run something that needs to be "cleaned out" of their fuel system, and that we shouldn't be burning our food supply. Corn has at least 2 better uses that immediately come to mind: Producing bourbon, and fattening up cows

I am. You just have to mindful of where to get it. I drove 400+ miles one way to NMRA BG Beech Bend this past weekend, I mapped out the station locations and called to verify their inventory and hours of operation, since I was racing I brought 15 extra gallons with me, but only used 5 gallons of that. I weigh 3,860 lbs race weight. Here's some pics & videos.

Damn good numbers there can you pm the lowdown on the details and do you DD your car on e85. Do you switch from e85 to pump and how often? Things in that nature. I'd appreciate it

How many miles have you been on e85? Is it a daily driver? Are you ever going to put some pump in it like beefcake said? Noticed any butt dyno gains? Your na I assume? Sorry for so many ?s

Yes I noticed a difference over my 91 tune for sure, it is my daily driver. I don't know how many miles off the top of my head, but it's been on for about 5 months....so I'm assuming about 4k miles. I will probably swap to pump if I take a road trip down to So Cal...not enough E85 stations to make it.

I can't believe you've never seen the thousands of Evo guys running it with no problem, with spotless fuel systems and engines. I didn't know we were talking only peak hp, so I guess my 20 isn't valid according to you? Even though I've seen it plenty of times. VMP made 14 peak by just swapping to E85, and not even changing the timing. After that, they made another 11. But apparently I'm wrong. I think there's more risk in running a 91/93 tune that's aggressive. You have a much bigger margin for error running E85.

For the price of $250 for injectors, and maybe a small cost for a tune update, I'd say the reward is pretty good.

I could care less about Evo's and I'm sure there are plenty that have never had a problem running E85. I just think your claim of it being a "clean" fuel is laughable. Why do so many tuners recommend running a tank of 93 every so often? Do you deny the thousands of pictures and reports on the web of the black goo?

And your claim of 20 hp sounded like a peak ho claim to me, because everyone seems to only mention that unless otherwise stated...my bad for assuming. What were your gains on E85? Ill check your svtp link later, so I can't comment on that. I still say properly tuned a Coyote is only picking up 10ish peak hp on E85

Something doesn't seem right in this clip. Doesn't the 5.0 seem to accelerate quick for only 402hp?

I haven't been on a dyno, so I don't know...and I certainly wouldn't have dynoed before and after. Read that link and you might be surprised.

Why could you care less about evos? Are their fuel systems revolutionary and black goo resistant? I would be willing to bet that the "black goo" affected cars were people who swapped to E85 with considerable mileage on their car, and junk in the fuel tank/lines. On a basically brand new car, I wouldn't expect the same results.

Because I don't particularly care for them and I'm not sure what that exact car has to do with this. Lots of other platforms and car people are using E85 on vehicles that aren't Evo's.

I'm not against using E85 at all. Around my area, we have E85 everywhere so there's a good chance I might end up with an E85 tune eventually. I just thought people should know there is SOME risk involved and it certainly isn't a clean fuel. It's always recommended to keep an eye on fuel components when running on corn.

 

[dubster99]

Sorry, you quoted before my edit. I'd be betting the black goo cars were people who switched with considerable mileage, and the E85 cleaned out the gunk from the tank.

There shouldn't ever be gunk in your tank. I've had quite a few tanks out in my day and have never seen any kind of gunk in them. In fact, they've always been spotless.

I read that link and I'm kinda having trouble following the gains from E85 and what he did with the tunes. Is it claiming 25+rwhp from E85 when he "turned the wick up"? Wish the dyno sheets were more specific

 

[Jeff's FRC]

I knew I saw a thread on this forum with someone having some E85 goo...

He's saying he got 13.xx WHP just by switching to E85, and not adjusting timing. Once he added timing, he got another 12-15 depending on where you want to call it peak.


I'm just speaking from my experience of seeing spotless fuel systems and engines after tens of thousands of miles on E85.

I've seen multiple posts like this that I pulled from another forum:

"Since you just made the swap to E85 than it's completely expected to see a filter element look like that. Regular gasoline leaves residue inside your fuel tank. Just like if you leave gas in a gas can for a long time you'll see a line of scum/residue where the top of the fuel level is. Once you swap to E85 the ethanol breaks down all of that residue and where do you think it ends up? The filter.

Since you've been running E85 for a few hundred miles the tank should be clean by now. However I'd check the new filter element in a month just to make sure.

Hope that helps. "
