Reply to "Weiand water pumps, what's up? ACCOBRA"

Julian,

I can't answer your question, I've never seen the business end of either of those pumps.

There are several Pantera owners, and Cleveland enthusiasts on the Cleveland Forum running the Flow Kooler pump, and they are happy with their purchases, the pump lived up to its claims of improving low speed coolant flow & resolving over heating problems. The impeller of that pump looks more like an egg beater than a centifugal water pump, but it delivers the goods. What Flow Kooler is hush hush about is what happens to the flow curve of their pump at engine speeds above 3500 rpm, whether it continues to pump more coolant (desirable), flattens out (not so good) or actually decreases (very bad).

I'm not aware of anybody using the Milodon pump, about all I can say is that Milodon parts are generally choice quality stuff.

Take a trip to Summit, have them pull a pump from stock & take a look for yourself, take your digital camra with you and snap a picture for all of us to see.

The Edelbrock pump has a cast iron, curved vane impeller, which is a highly efficient pump design, compared to paddle wheel type impellers as found in the oem pump & the Weiand pump.

If your motor is still tuned to pass smog, it will run hot. That state of tune is converting less of the combustion energy into work, and more into waste heat, hence higher engine temperatures. The ignition advance needs to be set to acieve highest intake manifold vacuum, as I have instructed folks to do on several occasions. Setting it that way will optimize the motor at low speeds & idle, convert as much combustion energy as possible into work, and as little as possible into waste heat, and reduce the heat load on the coolant system at low speeds.
