Sounds like you're just interested in freeing up some HP...forget the pumps, they wont do it for you. Electric fuel pumps are OK, as Pat said, but if you dont have to have one, use the mechanical one.. And for the water pump, the only advantage I can see is if you race the car, you can move the water around to help cool the engine while you're in the staging lanes between rounds...other than that, no advantage.
