If your running a riser set-up and find you are heat cycling it might mean trapped air.  The best solution is to build pressure to and the best tool is pump 1733.  We designed a impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure.  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. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot inline 6 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!
