    Nil...

    Zip... Nada...Zero.

    Especially if you flow it at the delta T it was originally designed for, 30 to 40 degrees. Even if you double the flow rate, 3-1/3 times zero is still zero.

    Oh yeah, did I mention the valves had to be wide open and there shouldn't be any orifices in the radiator piping?

    Zero.
