The little research I did on electric water pumps (on the archives of this board) is that the electric pumps simply don't move enough coolant to compare with a mechanical pump.

Is this false? In looking at some of the Edelbrock numbers on their website (to promote their product), the flow is 14 GPH at 2000rpm and 37 GPH at 5000 rpm. This sounds NOT as good as the electric ones (proform, CSR) I saw at Summit, which output in the range of 35 GPH +.

So I guess WHY NOT do an electric water pump? I certainly have the alternator and battery to support it. ALso, why is Proform about $140, and most of the others $100 more? I'm just wondering if there is something I don't know.
