1777CW 1963-1974 Inline 6 CW Rotation Riser 3 7/8" water pump

$69.00

If you are running a v belt with a riser set-up and find you have heat cycling it might mean trapped air.  The best solution is to build pressure to and the best tool is pump 1777CW.  We designed an 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. 

We developed this hi flow pump because trapped air can cause overheating in slow speed situation and stop and go traffic. It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures.

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