360 Radiator Shootout Begins!..

Yeah, I'm still not quite sure what to think of the actual wattage numbers. They generally seem low, but all the rads are being tested the same, so relative performance should be ok. I guess insulating the lines and adding the enclosure to minimize heat losses makes a bigger difference than I thought. I always new open air rad testing was a problem if there is any changes in air flow in the area of testing. I am probably also getting a touch of restriction from the test bench ports but I did try one test with and without the top cover and got results that were within a few percent so I don't think there is enough restriction to cause any major differences. I think most of it is in the line insulation work and testing all of the points with heat loads that near a 10C delta.

But you definitely do pay a premium for double thickness rads. It is almost double the materials costs for less than 10% performance benefits. The bigger difference I see with double thickness is generally half the restriction and usually better finishing/quality control. To some that would be worth the extra price, but best value will always be the slim rads.

Still working on the GTX, but I should have those results ready during the week. Almost half way done now and trying to burn through these as fast as I can.
