What is the difference b/t Agency Power IC, and other much more expensive ones?

good info all the way around. So I know how hard my car runs in winter when temps are in the 30's. Mark, are the intake temp numbers wrong on your testing. I am not sure that the data would be as meaningful at those temps. Or maybe it is even more meaningful? since if you see a diff at that low of a temp difference, they must really be good.

I did the test in the winter one day apart. No particular reason other then we do have winter hear and I had no choice. I also ran some dynos as well...

There seems to be two issues with the stock IC,
1. The end tanks
2. The flow, Heat dispersion of the core (correct me if I´m wrong).
Would it be any improvement to weld new better designed end tanks on stock 997 gt2 IC cores considered the possible negative open flow path design or is it just waste of time and money? It will probably not be near as good as aftermarket purposely designed IC, but it’s just a thought I’ve had.

I think the most useful information are two calculations: thermal efficiency and pressure efficiency. IATs alone are helpful, but the number itself is influenced by other factors. Similarly, "x% larger core" "x% better flow" aren't terribly helpful.
Thermal Efficiency (percent) = 100 x (Tin - Tout) / (Tin - Ambient)
...will give us an idea of how well the core does. Similarly, pressure efficiency will tell us how well the intercooler's flow parameters are.
