50/50 E-85 and 92 octane
 

Can you run half and half e-85 and 92 in our dsm's with no damage or is this a dumb thing to be asking?

Re: 50/50 E-85 and 92 octane
 

If you tune for it, sure.

Re: 50/50 E-85 and 92 octane
 

Also E-85 is 85% ethanol and that can corrode you Fuel lines and stuff. Thats why the new flex fuel cars have SS fuel lines and other fuel components. But If you run a mix I shouldnt be as bad.

Re: 50/50 E-85 and 92 octane
 

My buddy has ran a full years worth of E-85 on his dsm. The car has no corrosion side effects yet.

EvilEvo (Tim) is running E85 in his Evo. He was in the process of switching between the FMIC to a water to air intercooler, decided screw the intercooler all together and run methanol. Well we found some "issues" to running straight meth right away. Our biggest issue was the fuel rail needing to be annodized but we just found out the A-1000 isnt meth compatable. So he decided to run a intake pipe from the turbo to the intake manifold without any intercooler just to see how the car would run. Put some E85 in it and it pulls like a raped ape at 20psi. Seeing well over 250+ degree intake temps he still sees no knock. :D Besides the shit smelling weird coming out of the exhaust, its actually really cool. Amazing that you can go to the pump, pay $2.19 a gal and turn around and race the damn car on it. To add to that, if you had a FMIC, I wouldnt see why you couldnt run 30psi on the street with it. I think I'll have to try it to see how it works. 30psi on pumpgas... Mmmmm.

I mix 50/50 in my Daily Driver Galant

Re: 50/50 E-85 and 92 octane
 

Filled the Talon up with 100% E85 this weekend. So far so good. It definitely helped with the knock.

I'm using a PLX 300 wideband with the narrow band output being fed into the ECU. Adjusted the global fuel with DSMLink and it ran fine. Well as fine as it can with 1600cc injectors which so far I haven't been able to get the O2's to cycle on. I'm running a supra fuel pump, stock fuel lines, and an OEM 1G fuel rail with Buschur AFPR. We'll see how they hold up. I may replace the fuel filter soon, but other then that I don't plan to upgrade any other parts.

WTF?

Savin me some money nog!

Re: 50/50 E-85 and 92 octane
 

I suppose it does, but I can't imagine this is helping your engine's life any. Also, with the falling gas prices I question whether it actually is saving you money once you factor in the lower MPG of the E85 compared to gasoline. If its working and you are happy then more power to you, but I wouldn't risk it. You are running 47.5% ethanol and your engine, components, and ECU was specifically designed for no more than 10%.

Re: 50/50 E-85 and 92 octane
 

Well let us know if or what it recks so we all know.

Re: 50/50 E-85 and 92 octane
 

You're probably wasting money.

According to this article: "According to the DOE, a driver would need 1.4 gallons of E85 to travel the same distance as one gallon of regular unleaded gasoline."
http://www.theautochannel.com/news/2...15/006792.html

And according to Car and Driver:
"Since flex-fuel vehicles will burn either fuel, here’s how to tell which is the better financial deal. Divide the gasoline price by 1.33. If E85 is priced above the result, don’t buy it. Example: If gasoline is $2.50 per gallon, don’t pay more than $1.88 for E85. Unless you especially enjoy going yellow."

Whenever I do the math E85 is more expensive, but let me know if you find a station whose E85 factors out to be cheaper then regular so I can start going there.

Re: 50/50 E-85 and 92 octane
 

Gas was like 2.59, and E85 was 2.10 out by my house. I've never compared milage. Someday I'll compare it and see the difference. I know many will say I'm wasting money, and going to destroy the car, but I tend to do my own thing when it comes to my cars.

I listen to what everyone says, but in the end I just decide for myself, and most of the time it's against popular opinion (ie: homemade everything on my talon to save money even though it took me forever to build, Maaco paint job, mixing E85, using an ebay fmic, run Mahle Pistons even though they have shorter skirts and people who've never used them say they aren't going to last as long, etc.)

Someday I'll measure my milage difference I see in my car and see what my real world results are, instead of calculating what it "should be" because some engineer out there decided that's the number that will perfectly calculate the difference in milage for every application.

Re: 50/50 E-85 and 92 octane
 

E85 gives bad gas mileage but is great for boost. I have tuned a few turbo cars running anywhere from a few gallons of E85 per tank all the way up to 100% E85. I retuned an Evo 9 the other day that didn't make the best power the first time he came in with non-oxy fuel due to it wanting to knock too easy. He put a fuel pump in it, put in normal 10% ethanol gas plus 2 or 3 gallons of E85 and we were able to up the boost a little, add timing and run it a tiny bit leaner. It made 300awhp on our Dyno Dynamics with just an exhaust, MBC and retuned ECU on the car. The 16Gs on those Evos are crazy compared to what we use on the DSMs and MIVEC is cool.

Re: 50/50 E-85 and 92 octane
 

Sounds like Jim to me. Good to hear he made 300. I know he'll be happy.

Re: 50/50 E-85 and 92 octane
 

No it wasn't Jim. With Jim's luck, his will only make 195awhp.

Re: 50/50 E-85 and 92 octane
 

Haha
I can't believe how many people are going for the corn juice these days!

Re: 50/50 E-85 and 92 octane
 

LMAO, poor Jim. That is a sad but a true statement.

Re: 50/50 E-85 and 92 octane
 

I hope it works good. That would be real nice to save a little money.

Re: 50/50 E-85 and 92 octane
 

Ya especially when you get done with a build and need to fix it withing 20 mins again.
