Larry, are you assuming that performance (or any other single type of )
tuning is the main component of automotive decision-making? I must
wholeheartedly disagree with you there:
a) An electric water pump isn't likely to last as long as a mechanical one.
b) It will also cost quite a bit more. A stock pump for our cars might run
$35 or so. The one I just picked up set me back $280.
c) This will enable me to start the pumping on demand and regulate the flow
at a rate unrelated to engine rpm. Thus, my engine will warm up faster and
cool down quicker. I'll be able to run the pump no faster or slower than the
*ideal* amount. This will free up horsepower and that is a good thing!
Combine this effect with the (momentary) alternator cut circuit, and I'll
have almost no parasitic drag at all.
d) I might even be able to reverse the coolant flow so that it cools the
head first. That would pay dividends in knock supression. -another good
thing!
Bust that!

If converting to a water pump driven by an electric motor would save power
in a street car, the engineers would have converted years ago. They'd kill
their own grandmother to save one mpg across the fleet.
It's an interesting idea that won't give satisfactory results.
