I work on a road race car with an electric water pump. with a 2.0 Liter ford OHC engine the pump runs at about 10% most of the time. and We take the thermostat out because the controller controls the speed of the water flow to the preset temperature. It takes surprisingly little water to cool the engine at speed. Oh, and the car has no alternator, we charge the battery between races, our sequential shifter solenoids use more power than the water pump. (We have full data logging on just about every part of the car....) I can correlate the battery charge at each turn...
