Ed's spread sheet is the basis for the following note and attached pdf file.

At 5600 rpm, he shows 3901 Btu/min being rejected from the Radiators.

Using 50-50 EthyleneGlycol-water, I have calculated the flow rate of water through the radiators required to remove this much heat, as a function of the temperature drop across the radiator (which is the temperature rise across the engine).

You can see that for a reasonable delta-T you would like to have ~20GPM from the pump.

I would be very interested in the actual delta-T that Ed gets on his engine/radiators.
