Electric water pump conversion
I know this is slightly different than an actual electric water pump as it utilizes the existing water pump. Anyone used one? Anyone seen one?

I've seen adds for it. It's cool if there are no other options. Like said before the correct one is in the FAQ2.

It comes from the alt, which the engine has to turn, sure, but they wouldn't make them if they weren't more efficient. Take an electric radiator fan for instance... the mechanical fan has been dyno proven to rob 15 hp when the clutch is engaged. A typical electric fan that draws 20 amps at 14.4 volts only robs 0.38 hp. Yes, it takes electricity to run these things, but they are more efficient, so it takes less power from the motor than their mechanical counterparts.

My Corolla has electric power steering. (No pump, no fluid) They said they went with this for gas savings. A lot of people aren't big fans. It seems harder to keep center, and just feels different. (I wonder about reliability...)
I've seen the electric water pumps. It came, and went, thru my head. I still think their a neat idea.

The electric water pump still has to move at least as much water as the stock pump, which requires the same amount of power because it has to do just as much work. I still fail to see how an electric water pump will gain you any HP.
