    New HydroDrag rules

    23.3 FUEL
    23.3.1 Naturally Aspirated, Pro Stock, Super Stock & Limited Classes: Fuel must consist of unleaded gasoline only. For the purpose of this rulebook “gasoline” is defined as a mixture of hydrocarbons and oxygen bearing compounds with the following clarifications:
    Oxygen content must not increase the specific energy of the gasoline.
    Oxygen content must not exceed 3.7% by weight.
    Oxygen content must have been blended in by the refiner or the fuel manufacturer.
    Specific gravity must be between: .715 - .770 at 60°F (15°C).
    The only allowable oxygenates are ethers and alcohols. Epoxides (example: propylene oxide) will not be considered ethers. Nitrogen bearing compounds are not allowed.
    Most commercially produced unleaded fuels and oils will meet these criteria. However some may contain additional additives that do not to meet these criteria. It a racer is unsure about his/her fuel the racer should have it tested by a Technical Inspector.
    23.3.2 Unlimited Class: Fuel may consist of unleaded and leaded gasoline. Nitros Oxide systems may be added.
    23.3.3 NITRO METHANE AND ALCOHOL ARE PROHIBITED IN ALL CLASSES.
    23.3.4 TESTING: All competitors are subject to random fuel testing at any point during competition at the discretion of the race director or promoter. Refusal to submit a fuel sample will be considered and dealt with as if a sample were found to be illegal. If a sample is found to be illegal during a qualifying or elimination round that competitor will automatically and immediately be disqualified and the competition reinstated as the winner pending fuel testing. Winners of final overall rounds are required to submit fuel for testing immediately after competition. If a sample is found to be illegal that competitor will automatically and immediately be disqualified and the competition reinstated as the winner pending fuel testing.

    Why no methanol? To be competitive in unlimited with a 2 stroke it's almost a necessity

    100 % gasoline e85 looks to be outlaw. ie no alcohol. Might be different if they said no metanol. Futher e85 is around 36 to 37 % oxgen by weight where as e10 or normal pump gas is 3.5% so legal

    If you weren't in the "rules committee" your opinion doesn't count...at least that's what they told me when I made a simple suggestion in another thread.

    Sample question...

    Can you run E85? and if you do which class it can be run?
    I'm sure that many people here were not previously on the rules commitee.

    So there is no difference in the fuel rules compared to what they were previously. Word for word match on rules, no change. Since the precedent has already been set by many running e85 previously, and it has passed a tech inspection fuel test after the races, it has to still be be legal. It is unleaded gasoline blended by the manufacturer.
    But then you have this added which is new.
    23.3.3 NITRO METHANE AND ALCOHOL ARE PROHIBITED IN ALL CLASSES.
    Yes we need clarification please on e85.
