Flowkooler High Flow pump for the Oldsmobile 455 engine has a CNC machined billet impeller designed with an increased vane count and a reduced plate-to-impeller clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

This pump is commonly found on cars with AC.  The taller hub heights were used with AC cars to advance the fan blades forward 1/2".  They needed just a little more to cool with the demands of AC condenser. See pump 1575 if you need the shorter hub height.

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Olds Rocket engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!
