But the electric motor couldn't spin a stock water pump fast enough to keep up on the street.
Over the years the electric water pump has evolved into what is available today. The stock water pump was replaced by a purpose built pump designed to be driven by a electric motor all in one piece. Yes, they're expensive, but they're light years ahead of the old electric motor driving a belt driving a stock water pump.
I still have a car with a cement truck electric water pump on it (the pump they use to wash the truck down with when they finish pouring cement). It's the same pump they use on house boats to pump water to the kitchen and bathrooms. It works better than the old belt driven electric setup sold by Moroso, but not as good as what you can buy today. The car hasn't been started in years, but if I get interested in it again and the cement truck water pump ever quits or I decide to do some major work on the car, I'll be moving on up to one of the new high dollar pumps.
In the end you get what you pay for. You wanna play you gotta pay.
