on race cars, the battery or batteries are in the trunk, and are charged between runs. no alternator. soooo an electric pump gives cooling for the run, and does not sap HP. on the road, the pump would be charged by the alternator, and the resultant HP loss would be more because of efficiencies of the alternator. unless the water pump pumped less water... which could cause an overheat condition in an aluminum headed motor... not wise.
