[QUOTE="BlackBolt9, post: 5341335, member: 36489"] I was being a smartass about the school part;-) The only way to lower the system temperture (equilibrium temperature) is to further cool the water, which can be done with either colder ambient temperatures or with more radiator surface area. Now as to flow rate, what good does it do to show the heat supply a constant source of "fresh" water if you are not cooling that "fresh" water enough before it is presented to the heat source? NONE A high flow pump will cool things better as long as you don't exceed the cooling capacity of the radiator. Once you go beyond that point, the water no longer cools off enough before it gets back to the intercooler to remove the same amount of heat as it did the time before. In essence it is still carrying some of the heat from the previous time because it was moving too fast to drop off all the heat in the radiator. This could under extreme cases cause the equilibrium temperature of the system to increase as well. A low volume pump will actually allow the water to cool more therfore creating more heat transfer into and out of the water. You just can't go too slow otherwise the water saturates with heat quickly and can't absorb anymore way before it exits the intercooler. So there is a balance between what is too much flow and what is too little flow. I would think if the larger Meziere pump doesn't show much of an decrease it is flowing too much water for the thermal efficiency of the stock heat exchanger. Adding an aftermarket H/E would lower temps and maybe it would be capable of handling the amount of heat transfer needed to make the Meziere pump worth while. :shrug: Only one way to find out :thumbsup: [/QUOTE]
