    I am going to experiment with some E85 in my truck this weekend. I am running the fast efi so adjustments can be made to fuel pressure and fuel mixture. I was just curious as to how much to start with? I was think 70/30 fuel to E85 and go from there. Anybody have any ideas where I should start.

    What are you hoping to find in this experiment?

    I am always looking for more power and it is 30 to 50 cents cheaper depending which gas you use. I have a station
    2 blocks from my house that sells it.

    Typically straight ethanol requires 1.7-1.9x greater fuel volume to meet the same AFR. So even cut, there will still be an increase in consumption.

    As for power, not sure if you will notice much difference. Curious of your results.
    Do you have some fuel usage charting to verify any change in consumption?

    I am more in for the power vs consumption. The E85 is supposed to be between 105 to 113 octane. My son ran
    it in his BMW with a Burger Motorsports tuner and there was a noticeable difference in power. I have the fast ez efi system so I can up the fuel
    pressure at the regulator and also change fuel parameters from idle up to wot.

    Any change in compression in this engine? Or knock sensor to peg the timing off?
    Any way to validate power changes?

    I like experiments

    Can your fuel pump deliver?

    Compression is around 10.7 to 1. No knock sensor. I can limit/change the rpm with my MSD. I am hoping
    there is a noticeable increase in power cause I have now way to measure it. I am going to start with a 30% mixture
    of E85 and see how it does

    I called the efi wiz at FAST and he said yes to the fuel pump that was supplied with the kit
    he also gave me some parameters to shoot for, but said I would need to experiment.

    Is your butt calibrated?















    Or do you have another method for determining difference
    :haha:

    Like you I like to experiment, not necessarily with pistons melting, but we will see.

    I think you need to experiment with forced induction.

    E85 is go go juice with forced induction

    Sometimes I wish I would have gone that direction, but as it is I've only
    got a 17 gallon fuel cell and carry 10 gallons of extra fuel. That's stretching any long distance runs
