Now here's a really good idea, anyone tried this? the theory seems good to me:
Its an Australian company, who produce the Davies Craig water pump, and I can imagine with such hot air temps, something like this would be just the ticket. Being able to keep water flowing through the engine after shut down is a great idea.
Removal of the mechanical thermostat would also increase water flow, and the guts of the OEM pump (and/or pulley, but not sure of thats practical to remove, given the need for different cam belt length). Probably something to set yourself up for, before installing the engine in that case.
