electric water pumps.
they work great on daily drivers.
they also work great on race cars.
I run one on my 95 bird....the beauty of it for me, is I can cool the car off(going from 190 degrees to 170 degress in minutes) in the staging lanes before the next race, with the engine off!
parasistic drag from any accessory hurts any kind of mileage or power.
depending on the vehicle make, some e-water pumps come with an idler pulley built in, so belt routing stays the same.
