    Waterpump flow

    I have been searching online for waterpump flow and can't seem to find anything. I'm looking for a chart that shows flow by RPM using stock pully diameters, application is BBC.
    Does anyone know where I can find this?
    Thanks,
    Dave

    Water pump flow

    That is engineering data that you don't see commonly. I would contact a manufacturer tech line directly. They will have it.

    The only numbers I see are for electric pumps which is 35 GPM.

    Maybe we have a pump tech guy on here?

    You're right, not a commonly asked question. Would be great to see a flow chart on the different engines and pumps designed for those engines.

    Thanks, I'll check with a couple of the aftermaket manufacturers and see what they say. I will post the results.

    I am building a street car for a customer with twin turbos. Depending on boost, it's going to make a lot of heat at idle and I may suppliment the cooling system with an electric pump for idle to 2000 rpm, then let an underdrived conventional pump take over. There is such thing as too much flow thru the radiaton and was trying to get the facts down.
