Hi
Marko;
Full specs can be seen at http://www.daviescraig.com.au/
Last year I did full tests on the current draw, but I can't find that info
handy right now and it's to late to look for it, but IIRC it was approx 4amps
with the inrush current only ~6amps. The web site shows max draw 7.5amps. If I
didn't have so many other things to do in the next few weeks I'd install a
volt/amp meter on the pump/controller to take readings at various coolant flow
rates and plot them on a chart with temps; engines speed, MAP, etc... but
I just don't have the time right now. maybe in the spring.

Well at 7.5 amps and 13.8 volts the power consumed
is approx 100 watts which equal approx 0.134 HP. A couple orders of
magnitude less power than some "experts" had predicted would be
required. Your "experiment" has debunked another long-held myth about
the amount of power required to keep sufficient coolant
flowing. Good work, Todd - a great data point!
