Hi Dave

My pump is mounted up front on the radiator return and I just took out the impeller from the mechanical water pump. The thermostat is removed and I used the DC controller. I do not race the car but the temperatures in South Africa where I live get hot and the car seems to stay cool at about 95 Deg C. The pump is not turned off with the ignition as this prevents heat soak and it does not take long for the pump stop running. Having said all this I have not done a great deal of milage since I put the pump in as I am still sorting out other minor problems with her but when I had the mechanical pump running the temperature on the gauge was much higher. My header tanks are also high up. The one thing I would do differently would be to line the inside of the central tunnel to keep the heat down in the interior. I would use surgical neoprene as the lining as this has excellent heat insulating properties and I have used it on the inside of the front wall to reduce the radiator heat to great effect. It is quite expensive though at $70 US for a half meter square.
