    I would suggest the Racetronix fuel pump with the wiring harness.

    Injectors should be around 60-lbs. Siemen are a good brand. Some people also use FAST.

    You might also want to consider using methanol injection.

    Thanks,
    What methanol injection do you recommend. Also the kit comes with 42# green top injectors.

    AlkyControl - this is the only methonal kit I would purchase.

    Injector sizing:

    Flow Rate = (HP x BSFC) / (# of Injectors x Max Cycle)

    BSFC is "Brake Specific Fuel Consumption and on a F.I. application is generally said to be 0.55. For N.A. the standard figure is 0.45. Max duty cycle on injectors should be no more than 80%, or 0.80.

    If you use 500 hp the formula would be:

    Flow Rate = (500 x 0.55) / (8 x .080)

    Flow Rate = 275 / 6.4

    Flow Rate = 42.96 lb/hr injectors

    Assuming the horsepower level is accurate, it looks like 42 lb/hr injectors would be pretty close to borderline. Hope this helps.
