Here is the info that I have on the pump.
Get 30 percent extra coolant flow.
Flow Kooler water pumps solve low-speed heating problems by doubling the water flow rate at low rpm and idle. At 3,500 rpm, the flow rate returns to normal, to prevent too much water flow at high speeds. These pumps also last longer than a stock replacement. They use a specially designed steel plate on the impeller that traps water, eliminates cavitation, increases flow, and reduces engine temperatures.
