On my tr6 I have to order the gt6 water pump to get the same pump that is on my tr6. The pulley diameter is smaller than the parts supplier offered for the tr6 of the same year. This is the original engine in the tr6, but may have changed the water pump from original before I bought the car. In 100 degree F the water temp stays the same as other months of the year. I do have the 3/8 inch belt diameter though. I have not used the uprated water pump and have a stock engine. Just my two cents worth.<br></div><div><br></div><div>Regards,</div><div><br></div><div>Robert Perry<br></div><br><blockquote style="padding-left: 5px; margin-left: 0px; border-left: #0000ff 2px solid; font-weight: normal; font-style: normal; text-decoration: none; font-size: 10pt; font-family: arial,sans-serif; color: black;">-----Original Message-----

<br>Subject: [6pack] Fwd: Six Vane Water Pump
<br><br><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">We upgraded to the billet aluminum pump and aluminum water housing offered by Racestorations. 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?
