I have a CSR electric pump, and dual electric fans on my car. The car does not see any street driving though. As far as freeing up some H.P., maybe it did, but they only claim it frees up about 5 to 10 h.p. and in my opinion, hardly worth it for a street car. Most of the companies claim that on the average, they move around 35 gallons per minute. When the time comes, and I put my car back on the street to have some fun with the locals, the electric pump will be removed in favor of a mechanical pump, but the fans will stay. Think about what happens when an electric water pump decides to expire. It stops pumping, or causes an electrical fire. When a mechanical pump expires, all it does, most of the time, is leak, still giving you time to get to a place to make repairs.
