E85 anyone use it in their car?

[pashtrd]

I am building my motor in my Torino this winter, since i blew up my clutch at the grove last weekend. Anyone build their engine with E85 in mind as the fuel of choice? I am looking for some info as to what needs to be done to the fuel system, carb etc. Looking for someone with some hands on experience. max compression? cam recommendations? etc.

Why would you want to use it? Its cheaper yeah, but you alse get about 75% of the gas milage you would with a higher octane.

105 octane at the price of 87. I dont want to spend $8.00 a gallon on race fuel.

Talk to Kurt...I think he tuned his TT mustang using e85 if i remember correctly

Who is Kurt?

I think you didn't read the post above you. It needs to be like 80 or more cents cheaper for it to make sense. Is this car going to be boosted???

Well, up here its $1.00 cheaper when compared to 93. The problem is, everyone always compares it to the 87 price, but who runs 87 in their cars?

I will be converting over to E85 this winter probably. With a carb and some tuning skill you dont lose nearly as much MPG and you can tune for more power, so its all good.

E85 is a great alternative to race gas, as he mentioned.

Please explain.?
If i build my motor to run with say... 12:1 compression i need to run 105 (or more) octane gas at $8.00+ a gallon. Or i can run E85, burn a little more 25% or so and pay less than $4.00 a gallon. In reality I would need to be at the point where E85 gets half as much mileage before it would not make sense.
no boost, just thinking lots of compression. Again i am in the decision making stages now, just looking to talk to someone who has done it, I have read what i can on the internet, i just need real world experience.

Thank you.
have you done this to your car?

[TheRxForSpeeed]

One of the guys at the show with the Green Supra, name slips my mind, was running e85 for a turbo application. Had around 600hp if i remember correctly. Lots of rotary guys are running e85 also.

Thank you.

Not yet. I will be when I stop pissing away money on other junk.

If you have a wideband you can tune for Lambda and get (relatively speaking) good gas mileage.

i forgot where i read an article about that. it was in some gm magazine, about what you all need to upgrade the carb

[badass88gt]

You basically need everything to be alcohol compatible. That means stainless needle, good fuel lines, pump, regulators, etc. You will need more fuel so you will maybe want to look at the E85 metering blocks with the bigger orifices and passages.

For 12:1 it hardly seems worth it. If you have forced induction, it's worth it.

The consumption is as bad as everyone claims.

Around these parts E85 is as hard to find as 100 octane. :)

I would consider water/meth before considering E85 again. And I am a big fan of E85.

12:1 was to use as an example, not sure of any of the motor specs yet, like i said i am in the planning stages now. As far as availibility, there are 2 pumps within 3 miles of where i live.

I have a holley black pump, 1/2" aluminum fuel lines. I will be sumping my tank. is that adequate?

That's cool. Then I would say if your going to do it, make it worth your while.

I will be doing a conversion this winter as well.

Mostly a matter of making sure all your components are alcohol/ethanol compatible, upsizing the fuel system about 30%, and then retuning. I may run an ethanol/octane sensor from GM car as well just to have something to monitor in terms of fuel quality.

In my case I am checking the lines, upsizing injectors a bit from the 720s I have now, setting ethanol AFRs in my EMS and retuning a bit (more boost yay)
