Default Opinions on 21.5x5.5x2.5 core IC

So, im looking at this intercooler on ebay. Its only 2.5" thick but following these calculations that braineack that posted up, it should support around 300hp. That more than i would ever run and even if i did, i would have WI. My main concerns are to keep air temps low and be able to keep my A/C drier. I just want to make sure i have all my "ducks in a row" before i make a purchase.

then keep in mind increasing core thickness does not proportionally increase heat transfer capability. Each increment of core thickness will receive hotter cooling air. 3" in itself is plenty thick. Then you get into drag, and and it makes it harder for air to pass, and especially harder for the radiator to do it's job.

It's all compromise, but Corky will say that you want 6-7 square inches of internal flow for every 100HP.

internal flow area =
length of runner x height of runner x # of runners

11x12x3" core:
11 x .125 x 16 = 22 inē
22/.06 = 366BHP

18x12x3" core:
18 x .125 x 16 = 36 inē
36/.06 = 600BHP

Any suggestions/comments are greatly appreciated.

bigger how? taller? i was down there with a tape measure but i didnt really see much more room. 6" down from the drier is about as far as you can go.

I think he is showing you that there is still room above his intercooler.
