I'm also using an electric water pump as an addition to a conventional belt driven water pump. I mounted it as close to the radiator's output as possible, which is where both Stewart and Meziere said an electric "booster" pump should be mounted. I ultimately decided to go with the Stewart 55 GPM remote pump as it offers zero restriction to flow when it's turned off. It's controlled by one of the outputs on my EFI ECU. The other item in the photograph is my remote bypass thermostat housing.
