How much is too much intercooler?

I'm building this car here and the time has come to build the intercooler. I have a massive amount of space under the tail. The pics below show the actual size model of what space I have to work with.

I have a theory that at some point the diminishing marginal temperature reduction is offset by the amount of aluminim needed to build the next size up...something vague about thermodynamic efficiencies and some law named after an Italian guy. Anyway, I'm sure an intercooler 24" by 20" by 7.5" deep is unnecessary. That's 61cm by 50 cm by 19 cm.

Can anyone add any theory, science or experience as to what is a proper size if I have those dimensions to work within? Here are a few pics of a box I constructed demonstrating the available space...

Motor is a 3.2 revving to 6500 with 16 lbs boost. Target 475 hp. Air/air intercooler.


so thats what an intercooler's view of the world looks like..
