That has the 6 vane curved impellers. The temperature difference was significant. It was stupid expensive but totally worth it. I'm in Dallas so heat dissipation is important. <div dir="auto"><br></div><div dir="auto">On a side note, someone postulated that since the water moved more quickly, it spent less time in the radiator and that was a bad thing. My engineer nephew explained that the faster the fluid moved, the lower the temperature. So more vanes, more fluid movement. Better designed vanes, more fluid movement. All good. </div><div dir="auto"><br></div><div dir="auto">And, if you look at the design of the vanes in the original pump, well, who thought that was a good idea???? I guess it was cheaper to forge</div><div><br></div><div style="font-size:100%;color:#000000" dir="auto"><!-- originalMessage --><div>-------- Original message --------</div><div>From: Rochlin Robert via 6pack <6pack@autox.team.net> </div><div>Date: 12/28/19 7:33 AM (GMT-06:00) </div><div>To: 6pack@autox.team.net </div><div>Subject: [6pack] Six Vane Water Pump </div><div><br></div></div>Hi All,<br> Has anyone upgraded to the six vane water pumps offered by, among others, Flying Dutchman Water Pumps?
