    The best money you will ever spend is to send your stuff to a professional like Mike Kopchick with RAGE FUEL SYSTEMS and let them flow your entire system like you run it on the car. Tell them everything about your combo and how you plan to race the car. I promise you will not regret it and it will save you money in the long run. There a lot of very knowledgeable people on here that will do their best to help you but without someone flowing your stuff all it will be is best guesses . One set of burnt pistons or a damaged short block will cost a lot more than the money spent on a flowed system. You have spent a lot of money to get where you are now so now is not the time to pinch pennies. Good luck. RAGE 's number is 843-623-3500 or look on their web page.

    Find a genuine tuner !
    Just because a guy can run a flow bench that doesn't make him able to tune your car .
    I bet there are plenty of crew chiefs that have never run a flow bench !
    Race cars have to go down the track , dynos and flow benches don't .

    Bob is right , a tuner is what you need until you learn enough to go it alone. But a good tuner that does not know what your system flows is going to be guessing at it to start with. He may get it right the first time, maybe you junk the motor in a few runs. If you we're going to just run a simple bbc deal with just one high speed and no timing control or fuel management it would be easier .

    The first thing you have to know to tune a car is what the GPM the pump puts out.Then blower size,overdrive,engine size, and then elevation(air density).Most fuel pumps are rated in fuel flow, but it's always good to have it flowed to know for sure.
