Wait.....so are you running stock internal dsm fuel components and you are seeing no problems? I never believed that bs about it "corroding" aluminum....but you never know...

so are all DSMs just a A/F adjustment away from running e85?

And a time bomb for lines to just disapear on you.

It does eat up the DSM gas lines, but it takes some time. If you want, run the fuel, or about a 1/4 tank to find out. If it is bad you can always pump the tank and just run a little rough for a while. It won't mess up your O2 sensor, they had a few bad batches when it first started coming out that scared everyone away. They had too much water in it, and was fouling up O2 sensors even on vehicles equiped to run it.

From what I understand e85 will take a long ass time to corrode lines and dry out seals. It isnt nearly as corrosive as Methanol but since they are both alchohols people tend to associate them both as a big no no for stock fuel systems.

Gravy · 04-27-2006

Main problem is tuning, it will probably break some seal on these older DSM's with stock lines and O-rings. But for the normal, or "New" parts. You should have some time on them.

Talking on another form about running a N/A car with E-85 for hp gains.... can we say 11:1 compresion ratio?

iceminion · 04-27-2006

I am fully aware of the risk, and if it corrodes throught my stock fuel line, I shall just run a new SS one..... thank you tim for clearing up the methanol/ethanol differences.

So, -IF- i was gonna do this, would a SAFC1/2 work? from what I can remember you can load up 2 different fuel maps, depending on what fuel you are running.

So, is it that easy? just a safc re-tune?

one additional point, as I understand it, there is alot of clay and other anti-engine sediments in standard gasoline, and ethanol has (almost) none.....so engine wear is going to be cut way back......I spose nobody cares here because we rebuild our engines periodically anyways

11:1 isn't that high for an import. S2000s come stock at 11:1 compression ratio and add boost to those on pump gas. I have tuned 12.5:1 compression dail driven pump gas Honda's before. The gain from going that high really isn't worth it though. The power returns diminish more and more as you go higher and higher.

Gravy · 04-27-2006

Along with an SAFC you'll need injectors, i'd go 650+ since you'll have the safc to control them, 190 or larger to help get the extra fuel you'll need.

With that you'll be running ethanol in your car, and just have to wait for the lines to corode away. If they do that is, havn't found solid proof it will. Only speculation and proof that alcohol does.

Stupid zombie thread, I started reading the first page and saw a post from mike (raptor) and I thought it was private eye time.

I finally have a sig with information on my car so people can stop assuming im a freaken noob (all my fault)

So yeah, after I get all the oil leaks fixed on my car its gonna be time for the e85

CDeutsch · 04-27-2006

Does E85 not ignite like gasoline? Replacing a fuel line is one thing, but what if your car starts on fire before you notice you have a problem?

Gravy · 04-27-2006

First off, if your car starts on fire, you probably have a gas leak somewhere.

As long as your not like me, and forget to plug in your fuel rail, you'll be perfectly fine.

Anyone got this going yet? Back from the dead!!! I'm kinda thinking about it.

Thor06 · 07-06-2006

I was too, but I would rather have it running now than waiting to get the conversion done and having to pay for it all.

CDeutsch · 07-06-2006

I have some 1600cc injectors on order. I'll let you know how it goes.

It was going pretty good for Jim (TalonFiero) and the curiosity finally got to me so I'm going to see if it allows me to run more boost in my Talon.

98gstaherns · 07-06-2006

Do you need injectors that big? Or would 550's work?

I'm running a 2.4 with a 50 trim and I use DSMLink so I figured why not. 780's weren't cutting it.

550's may work on a stock car running stock boost.

When picking an injector size you'll also need to determine wether you're going to run straight E85 or a mix.

98gstaherns · 07-06-2006

Sorry I didn't mean as asking do YOU need them I meant in gernal for e85..Sorry I'm dump somtimes. Gotya! Thanks

**Shane@DBPerformance** · 07-07-2006

E85 requires a lot more fuel flow, so you need much bigger than normal injectors and a fuel pump(s) to back it.

AJ · 07-07-2006

I need to start looking into this as an option for the Jeep. That big V8 drinks like a fish.
