  • If the stat is working as it should, everything should be the same as w/standard belt drive pump. Of course I don't run a stat, I run a blanking sleeve to slow the water flow down so that it will stay in the rad long enough to give up the heat.

  • dude, pushrod v8 sucks for racing.

    it takes way to long to get rpm.

  • I was about to say your missing a V8.......Buuuut water pump also fits....LOL

  • heat does NOT dissipate faster, the faster the coolant is circulating through the system. It does to a certain point, then heat dissipation starts going BACKWARDS.

  • just slow down the speed of the pump!

  • Hi, I love your informational videos but in this case freonr2 has made a very valid point. I know some of the thinking used to originate with the A series in minis, they ran hotter with no thermostat fitted, however this was due to the turbulence created by the water pump actually slowing the flow.. This was not obvious and gave people the opposite impression.

    I am sure your engine temperature will drop without the restrictor... once again thanks for uploading so many interesting videos

  • The water does not have to stay in the radiator long enough to give up heat. Increasing flow will increase cooling all else being equal (say, short of the pump itself adding extra heat by running out of efficient conditions). This is a common fallacy with water to air coolers. If your goal is as cold as possible, you want to maximize water flow just as much as you want to maximize air flow over the radiator. Just like running a smaller ground cable is bad for electrical flow.

  • I can't imagine it would take any longer to warm up if the thermostat is working correctly. What say you John?

  • Ah, my bad, a bad misread.

  • Yeah yeah yeah we know. What MrGuvEuroman asked is what are the "disadvantages"
