Those interested in the electric water pump have a new friend. BMW has gone
to the electric pump on the new 2006 BMW 330i. This is a 6 cyl, 255 hp, 3
liter engine and I doubt BMW would have made this step without lot of
testing at all temps and hp outputs. The April 2005 issue of "AUTOMOBILE"
has the article on the car - the water pump is just a sidenote - they claim
it saves 2hp and they were very weight conscious on the engine. Looks like
you could mount it anywhere and have a reliable, mass produced, high output
pump. The article mentions it is computer controlled.   Herb Sanders
