Electric water pump
Discussion
Any point?
Three reasons for my question:
1) the boiling in the turbos after shutdown can't be good even though I know it aids the convection of cooler water into the housing, with an electric pump you can have it run on after shutdown to help combat it.
2) the plastic vanes in the standard pump (I think?) must be a weak point, has its own drive belt that can snap and associated bearings etc that could fail
3) the pump is probably heavier than a Davies Craig for example, you could maybe remove the standard pump altogether along with the belt and pulley and even the thermostat by speed controlling the flow.
Am I talking out of my arse?

All I know is if after a session on track I don't release the pressure from the cap within a minute of turning the car off, the pressure builds up and finds a way to leak. So long as I release the pressure (steam from the kettle) I never need to top up coolant.
Where did you get the pressure release cap Graham? mine has been losing a bit out of the standard ProAlloy cap since getting the header tank fitted so I was going to upgrade the cap.I spent a lot of time researching this to try to aid the cooling of mine.
2 types of stock pump, plastic blades and metal blades, it's also very light so you won't get weight saving unless you reduce the amount of water in system.
The volume of water that must be moved on a 500-600bhp car will be higher than the largest Craig Davies can flow so you have to spend a lot on the better pumps(that are heavier) for them to be spec'd to cope..... Some in US have used the CD without issue yet but the maths didn't work and I wast prepared to risk it on track.
I made a number of small changes and so far the water is now 100% under control on track even at full power and revving to 8000rpm so I think when refined the stock pump is good enough for me :-)
