Cliffs.

To run E-85 you need bigger injectors.

E-85 runs best at around 8:1

You can run more advance, and it cools you intake temps because it is alcy, so SS owners could use it in their meth injection systems too. (With proper tuning of course)

E-85 is 102 or better octane.

It's interesting to look into at the very least guys. Since the majority of you run some form of forced induction.

Also note that Rhys runs his Solstice on E-85, so there's a HUGE ammount of tuning info right there straight from GM.

 

E-85 eats away at fuels systems that are not made to handle the more corrosive ethanol. This would be bad for anyone to run who doesn't have a flex fuel vehicle. The only thing an ss could run is the 10% ethanol blend.

In Gm FFV's they use less rubbers in the fuel lines and gas tanks, use only stainless steel gas tanks, and change any other seals over to a material that can handle ethanol.

 

I just use 109 unleaded mixed with Toluene. Equals out to like 112 octane or something

 

It is not corrosive to the fuel system or the engine. This is a myth and ethanol is often confused with methanol, which actually have corrosive properties. Some models before 1988 on the other hand may have some parts that is not ethanol resistant.

GM does all of that so people don't have to change out their fuel system stuff after 20 years of never being replaced. IF something's gonna fail it will be in a year or so. And a guy on LS-1 Tech has been running 2 years so far. ALl you need is bigger injectors than what you'd use for gas and a retune. Probably use 42s on a stock balt and be alright. I'll be using 88s caus I can't get anything between 55s and that number.

ANd if your honestly that afraid of your fuel system rusting, why even run methanol to cool the intake? Its' more corossive than E by a long shot.

DAAAAAAAAAAAISY DUKE

MMMMMMMMMMMMMMMMMMMMMMMM, MMMMMMMMMMMMM, Goooooood

 

Its' just a sugestion for all the guys wanting to run a 2.5" pulley and 10:1 pistons. Can you say 400whp?

 

Defiently some interesting info in those links. I especially like the 900hp mustang running on E85.

 

He is right, E85 and Racing Meth are too different animals totally.

I will repeat what he said and Add this, 95% of the cars made after 95 are FINE on a 85% Ethanol 15% Gas and will not HURT ANYTHING. It will actually CLEAN YOUR ENGINE, FUEL SYSTEM and other things while your running on it.

Its all GOOD and nothing BAD ABOUT IT. The only thing that is produces less energy than Gas so you have to burn more, but that's fine, its usually less than 1-2 MPG on most cars and for the cost and performance gain, its WORTH the trouble.

You can make your own -

Even walks you through the permit process

 

My buddy Darren runs E85 in his 8 sec Turbocharged Mustang . Its cheaper than race gas

 

hmmmmm interesting

 

I am gonna run E85 next year in my car. It has many many benifits to its use.

 

So Don, how do you plan to add enough fuel? Are you ging to increase your injector size agin? I talked to an STi owner at the track and he ran E85 but he had to add something like 30% more fuel when he ran it.

 

I intend to run a larger pulley to start until get it dialedin and then go from there. We arent even maxing the 60s yet so there is still room to grow there. I am aware it does use more fuel I have been researchng this for along time now.

 

E-85 is not good for our fuel systems. there is different parts to a E-85 vehicle, like the injectors,the o rings on them and the fuel pump itself. the E-85 WILL eat the lacker off the copper wire that make up the inside of the injectors and fuel pump. GM dosen't recomend more than a 10% mix in non-E85 vehicles.

 

Don't you need a different O2 sensor to judge the AFR for your closed loop calculations?

interesting is all i can say

 

Nope you actually don't you just need to remember that Stoich for E-85 is 9.765, but your AFR gauge will read 14:1 You will need to compensate mentally for this. Though running a wideband is a better iea so you don't get confused.
