I run it with their EWP controller and have the water temperature set for 190 degrees. Even at full race speed (8000+ RPM) the water temperature does not exceed 190 degrees. I would add the following caution. The thermistor that provides input to the EWP controller MUST at all times be in water. In my first installation I had it barely in immersed in water and it cost me a blown head gasket, as the pump just stopped running. (Default is designed for pump off on EWP controller failure. I would have made it pump on full blast on EWP controller failure. THis is how I have modified it at this time.) I do not use any mechanical pump at this time. Good luck.
