Mechanical water pumps rob crankshaft horsepower just to keep coolant moving, which matters most on a big block being built for maximum output. This CSR billet electric pump takes that load off the crank entirely, circulating up to 37 gallons per minute on its own 12-volt motor instead of a belt-driven impeller.
