Here's the response from the guy who installed it in this road racer:


Perry,

I am thoroughly delighted with the performance of the Davies Craig pump.  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.
