RE: Electric water pump

RE: Electric water pump
The electric water pump is a mixed bag:
One advantage is that if you're drag racing you can set up the electric pump and electric fan to keep cooling your car down even when you've got the engine shut off--that can help you be nice and cool before each run.
As far as HP goes, I have seen Dyno results as high as+8 HP (peak) on an engine with minimal mods. HOWEVER, if you have UDPs, then adding the water pump gives you essentially nothing. UDPs already slow down your water pump a lot. So the change from UDPs to UDPs+Pump is minimal at best. That is also a bad combo becasue now you're putting more demands on your electrical system thanks to the pump, but you are also diminishing alternator output due to the UDPs.
A disadvantage of the pump aside from the increased electrical draw, is that you have to worry about longevity. The motors only last so long. On the other hand, the mechanical water pump is extremely durable.
I would only run the Electric pump for race applications where you wanted to cool between runs. For other purposes I'd stick with the stock setup.

RE: Electric water pump
I believe it helps reduce some weight as well off the nose of the car.So in all your getting a few ponies,better cooling & weight reduction(our cars need it!).I say its worth the 300.00.....
