    Default Race Fuels and Cobb Tuning

    So I'm planning an e85 tune next month with @richierichness.

    Found this site that supplies race fuels where I would like to buy a drum for the track day in February.

    RACE FUELS PTY LTD - Fuel Delivery Service

    As I don't intend on using this tune as a daily, I wanted the most reliable/highest mix to make sure the e85 tune is the best it can be. These are the specs they sell.

    E85
    http://www.racefuels.com.au/PDFs/SPE...%20Ethanol.pdf
    Ethanol (100FG) 85%
    ULP (98 Octane) 15%

    That being said, there are some other fuels on here I wonder would work well with the right tune in our cars.


    Elf 105
    http://www.racefuels.com.au/PDFs/Elf_Perfo_105_SPEC.pdf
    RON 105
    MON 98
    DENSITY (kg/l at 15°C) 0.740
    AIR FUEL RATIO 12.1

    OXYGEN (% m/m) 16.3

    Elf Turbo Evo
    http://www.racefuels.com.au/PDFs/Elf_Turboevo.pdfRON 101.7
    MON 88.6
    DENSITY (kg/l at 15°C) 0.770
    AIR/FUEL RATIO 13.57
    OXYGEN (% m/m) 3.5

    There's a big discussion on MSF about the difference between "c85" and "pump e85"

    Both are 85% ethanol, but the is a big difference in the way they're refined

    Will see if I can find it

    the short version of that thread, the 50-50 pump e85 mix (ie e42) is good for ~700awhp in the 6... (that's psychophyr's 6)
    for the 830whp one they used c85, which is e85, but better (think of it as the 98ron version compared to 95 ron)

    they are also looking into VP109, which is a 109 octane race fuel
