Does anyone think it is beneficial to install a electric water pump. From what i understand, the normal water pumps are run off a belt that comes off the engine. This would mean that the engine would use some of it's power to run the water pump. If an electrical water pump was used then the engine would not lose the power normally needed (i'm guessing the amount of power is minimal).

What does everyone think.

IMHO The minimal power gain would be lost buy what would pobably be a heavier piece of equipment.

The amount of power would be microscopic.

Again, that is my 100% totaly uneducated opinion.

I wouldnt touch them with a ten foot pole...

The original article showed that you actually lose power due to your alternator over working.

Lantis, I had a look at that website but the story was deleted due to legal reasons.

I found this article at another website:

Is that true? 15-20% power loss from Water Pump?

Well you really dont know.

The one thing with Autospeed is they do independant product research but they only do it on one car. Mods like that may work better on different cars...

But that link there appears to be quoting a lot of what Davis-Craig promote and they sell the product so they are not going to say its ****...

So in the end the answer is "I doubt anyone knows how it preforms on our motors"

The water pump is run off the cam belt! which means the pump needs to be there to act secondly as a pully for the cambelt! stuffed if i know how u would go about putting an electric one on it! waste of money + all sorts of dramas for very little gain!

I guess an electric pump would be a constant load, giving you more power higher in the rev range and drawing more down lower. As stated earlier it puts a load on the altinator (1kW off the pully = 1kW on the altinator).

Most engines I've seen use the waterpump as a pulley for other devices, so it's going to be there in some form. It may as well pump coolant around the engine.
