    E85 set-up questions

    So, for those that have converted to E85 that are running injection, What kind of jet/ tune-up changes did you make? Does anyone know were to go to get info on this?

    I have a 96 Ed Quay Dragster (1830 lbs.) that currently runs 7.90s @ 170. mph in the quarter (about 700 horsepower est.) on Methonal.

    My car runs a a Rons Flying Toilet Injection system. This is a constant flow mechanical injection system w/ a Waterman .500 pump that turns 4.85 gal per min. On Methonal I'm running .31 nozzle jets and a .70 main jet with a 6 lbs. relief spring.

    I am very interested in converting to E85.

    Is anyone one here currently running a similar set-up?
    Can anyone give me an idea of were to start ?
    Can anyone put me in contact with someone that can help me with set-up?
    What kinds of temps should I expect on an EGT system if I'm running 32 deg. timing?
    Should I change the timing in my car on E85?
    What type of water temp. gains should I expect to see during a pass on E85?
    What type of Air/ Fuel Ratio numbers should I see on my O2 gauge?
    Is there anything else I should know about E85 before running it?

    Your help will be greatly appreciated. Thank you in advance.
