Generating an incredible 37 gpm of coolant circulation, CSR billet aluminum electric water pumps give you the flow that you need, without costing you horsepower. CNC-machined from T-6 aluminum, these lightweight pumps have a direct-drive 12 V motor, spinning a redesigned impeller on a stainless steel shaft. These pumps draw just 5.8 amps and because they don't run off of your crank, they won't eat up race-winning horsepower. Other features include corrosion-resistant anodized finishes in several colors, superior RFI suppression, and a removable center section for cam adjustment or replacement.
