Question for Maggie owners who have switched to E85

I have been reading that a few people on here have tuned their magnacharged GTOs to run on E85. The results are quite impressive, and there is plenty of E85 to be had around here.

However I am concerned because as I understand it E85 is not compatible with (as in tends to dissolve) certain materials, one being aluminum.

I am not too concerned about the manifold or any of the other aluminum parts with the maggie kit except one...Are you guys switching to a different fuel rail? Have any of you seen a problem using the aluminum fuel rail with E85? Anyone taken the fuel rail apart to inspect after a lot of E85 use?

I did not switch anything from the kit...I did put a walbro 255 pump in the tank to support the flow, and went with 60# injectors.

I haven't had any issues, running it everyday since last September. But I haven't taken the rail apart to inspect so can't say for sure.

Hey Steel Chicken....dont you run E85 and Maggie set up?whats your take on this thought?

E85 is boosted cars best friend. only downfall is worse gas mileage, more expensive thangas, and takes bigger injectors than gas does. However i would trade all those things in a second to run E85 since there is quite a bit more power to be had with it, and safer power at that.....sucks that it is few and far between here in Texas.

all my knowledge of it comes from the srt4 forums, where it is VERY pooular. you might sneak around over there for some answers.

problem is our cars ARE NOT made for e85. the lines and just common things that the GAS come in contact with isnt compatible with e85.....it wont show up right away but in time it will! Car will run great on it though! if you are going to do it, do it right. you got to change out EVERYTHING to S.S. or something that E85 will not hurt in time.....

Sorry, I never saw this post.

E85 will not hurt your car. The days of the 1970's and people dissolving carburetor floats and rubber hoses are gone. Any car made since 2000 or so and later can handle ethanol (from a corrosion perspective).

As far as corrosion of aluminum, it does corrode, but ONLY on the surface. Once that corrosion takes place, it stops. Think of it as a microscopic glazing. Theres a great deal of factual information on this around if you go look.

I've been running E85 in my GTO for 2+ years, and ive had parts off, ive checked lines, fuel pumps, etc, and it all looks clean. Ive talked to people who have run ethanol for 5-10 years (esp in northern Europe) who also report no issues.

There is alot of misunderstanding out there about ethanol. Maybe in the 10-20 year time frame issues might show up, but I seriously doubt it.
