I hear of guys running e85 in their grand prixs. Are there and mods that need to be done to use this gas? What are the benefits? And does it have more octane than 94?

Larger injectors and a tune.

you are correct sir. along with changeing your fuel filter a couple times because the e85 will clean your tank out.Originally Posted by Sabrewings
i might be selling a set of 65# injectors coming up. i need a new transmission...
benefits: 105 octane all the time, cleans out the motor
cons: you have to use more fuel, but the fuel is a little cheaper

i would consider doing this, too bad e-85 isnt available anywhere near me, i love the thought of running 105 octane all the time

BH:
The E85 is quite a different animal, and is very corrosive to the entire fuel system. Vehicles that are OEM equipped to run on it are manufactured with parts that will withstand the volativity of the fuel.
Putting E85 into a vehicle not made for it will most likely result in a big repair bill for you later if not sooner.
I would research it completely so you know what you are getting into before you do this.

Modern vehicles are ready for E85. It's older vehicles that were built before E10 become widely available that you should be cautious. Any vehicle that can run on E10 already has synthetic seals in the fuel system and E85 will do no harm.

whoever told you e85 is corrosive was smoking crack.
read a chemistry book. ethanol (pure) is not corrosive. e85 (85% ethanol + 15% gas) is also not corrosive.

I have a 2007 grand prix GT along with the mods in my sig, do still need to change injectors to run E85?
Thanks

Gentlemen:
After reading your postings, I did a bit of research, and confirmed that e85 is somewhat corrosive as is gasoline.
The point to my posting was to encourage BS42 to make sure he has all the facts before he fills up his GP with E85.
I do know that E85 operable vehicles that are OEM do have different components in their fuel systems to make the vehicle work properly with E85. Common sense says they would not do it if it was not necessary.
While I do not claim to be a know it all, I have seen a lot of bad advice given out on internet forums over the years, and would not want to be the victim of it.
You can run a diesel engine on kerosene if you need to, but that does not mean doing it would be right or good for the car long term.
E-85 ethanol is used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel engines are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. The primary differences from non-FFVs is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system, the use of fuel pumps capable of operating with electrically conductive (ethanol) instead of non-conducting dielectric (gasoline) fuel, specially-coated wear-resistant engine parts, fuel injection control systems having a wider range of pulse widths (for injecting approximately 60% more fuel), the selection of stainless steel fuel lines (sometimes lined with plastic), the selection of stainless steel fuel tanks in place of terne fuel tanks, and, in some cases, the use of acid-neutralizing motor oil. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used.

yes. yes you do. the stock injectors wont run enough fuel to keep up on e85. youll need to use about 30% more fuel.
the reason why ethanol is worse off than gas is if your car sits a lot youll have problems with water collecting in comparison to gas. that is what will eat away your fuel system not the fuel itself. if your car sits a lot i would not suggest running e85, but if you start it up every so often or drive it a few times a week at least then youre money. e85 will not eat away anything any more than regular gas would so i wouldnt be scared at all to run it.
ive done my fair share of research on it as well since i am planning on running it at some point.
05-17-2009
What Injectors would I need to run? And where is the best place to purchas them.
05-17-2009
im not sure which ones you need for your car. i would look at ZZP for what you need and then try to find them somewhere else cheaper.
05-17-2009
thanks bro

You'll need PCM tuning or an AFC to use different size injectors.
