I have seen that some reccomend getting either the UPD's OR the electric water pump. I already have the Steeda UDP's, so would adding an electric water pump not give me any sort of a gain?
We are running the version from a French company (Mezier or something similar). Nice thing is it has an idler that is the same size as the normal water pump pulley so that the normal belt will fit and work just fine. At the strip, we remove the belt to get rid of all the parasitic drag since the water pump runs off the battery. Makes it a lot harder to steer, but makes a measurable difference in ET.
