Hi Blake,
Well, unfortunately we run into a thermodynamic limit in that the closer the air temperature gets to the coolant (actually the core metal) temperature, the less heat gets transferred from coolant to the air. But, if you can figure some way to refrigerate the air to about - 200F then we can really get rid of some heat {:>).
One of the things that makes this stuff so interesting (as well frustrating) is that we are trying to use simplified models of a very complex physical process to work with. I always say just remember that models are nothing more than dumbed-down version of the real world. Don't be surprised that they don't always give you the same answer.
I wish I had taken a course in Fluid dynamics at some point in my checkered career, but guess I'm sort of doing that now {:>).

If we get an even better core, we can take a DeltaT of 300F.
