Message	We finally found some time to do an initial run of our radiator test rig and it went pretty well. These are the initial test results for the 3 new AshSPEC radiator cores. There is clearly a winner in this testing. This test was performed with 3.5 gallons of a 50/50 water/glycol mixture, starting with the entire system at 200F saturation. Temperature drop was logged every 5 seconds from both thermocouples, temps averaged, and the plot you see was generated. As for the details of these radiators in the test, I'm not open to elaboration. I'll simply say that there are variations in each design. We seek to quantitatively determine which radiator design is going to be superior and draw upon the results to further enhance the design of a new radiator. More testing on other aftermarket radiators to come very soon, including a test for the OEM radiator. At the moment we are only waiting on the AMS radiator to arrive so we can test all of them: Mishimoto Z1/Howe AMS AshSPEC double-row, double-pass (the original) OEM This testing process went well and served good purpose - we ended up trimming down to 3.5 gallons of coolant as 5 gallons simply too far too long to heat and cool. We have the entire procedure down pat and will be a breeze to reproduce for future testing of other radiators. So, just wanted to give an update - things are moving forward - just waiting for the AMS unit to arrive and we will get back to this. If anyone has any suggestions or something they would like to add to this, that is more than welcome. For additional information on this testing, see the following post which has the testing procedure we are using.
