I want something that wont stop/slowdown during high rpm operation. sadly, thats a problem with OEM pump.
and I want to keep it as *OE* design as much as possible.
This pump is something that exactly what I want.
Im thinking of getting the Greddy Pulley set to go with this pump. I dont like to underdrive anything, but I want to lose some weight, even by 0.5 lbs Im happy.
So as soon as this pump is out, Im gonna get the Greddy pulley set (and install it together)

Look at your question and compare it to the posts before it.
We are talking about a device that cools the engine.
You wondered about how much heat the pumping action would add to the system, and the differences in this "heating" efficiency between an electrical and mechanical pump.

Exactly and if you are giving that adiabatic efficiency is not going to add to or reduce the heat in the system between a mechanical and an electric pump, my question is how is an electric pump going to cool the system better than a mechanical pump of good design and efficiency?

an electric pump might be a good idea, but the power gotta come from somewhere, and electric pump still generates heat. also, when an electric pump fails, it usually fails right away(then good luck to ur engine)
mazmart mechanical pump on the other hand, fits in the stock location(I assume), will speedup itself according to engine load (the engine spin faster so does the pump, stock pump stops when it reach higher rpm), and usually it takes a while b4 a mechanical pump give up the ghost

The generated heat is not an issue.
Increased flow is. Will an improved OEM mechanical pump flow more than 20 gal/min at high RPM? Possibly.
Will it do that at idle? No.
All we care about is total flow. It is up to the other components of the system to deal with the heat.
Also, an electric water pump will, at peak, draw about 8 amps, which is significantly less than both fans on high. It is also WAY less power than a mechanical pump. We are going back and forth about 8 or 10 HP at peak that a mechanical may draw. Keep in mind, 8A is only 1/10 of a horsepower!
The "problem" with an electrical is packaging. As an OE pump replacement, it will require some interesting machining.

why dont' we just wait for Paul to come back and give us all the details?

(1) it goes in the stock location and there is no change
(2) the stock pump gets removed and capped off and the electric pump is located remotely elsewhere
(3) the stock pump remains in place and an electric pump is added as auxillary in a remote location.
