Why would it not work to plumb an A/C coolant line through the intercooler using fabricated dedicated lines and install a valve to divert compressed A/C coolant (before it gets to the condenser in the car) into the intercooler prior to launch? It seems like there is a source of "cold" allready built into most engines (i.e. the A/C). By running the cooant through the intercooler it would absorb heat and one would not have to deal with fans and etc. I'm not suggesting puting a condenser on top of the Intercooler and blowing air through it. I am suggesting using the intercooler as the condenser and running cold A/C coolent through the intercooler in a closed loop system that would return the coolant to the compressor for recycling.

Besides all that, this seems like a much more involved project than mounting and wiring a fan.

This difficulty is overcome by a simple application of common sense, which has nothing to do with the laws of physics: start by assuming that the Subaru engineers who designed this system in the first place aren't a bunch of complete idiots. If you start with the assumption that the intercooler and hood scoop setup built into the WRX actually functions, then examples such as fire hose and screen door begin to fail the plausibility test and then can be eliminated safely. Then if you add to this the fact that the intercooler setup not only functions, but is replicated across several models of cars and almost five years of production, it seems a safer bet that the fire hose/screen door scenario simply never happens. In other words, give Subaru some credit -- they did a bit of research, rather than just throwing the TMIC up there and sticking it down with some duct tape. If you honestly think that the TMIC from the STI engine emerges from the factory already in dire need of attention, then you'd probably better move on to another make and model of car in the future.
Once you're willing to confine yourself to reasonable examples that actually might have real world applications, I'm certain it will all make perfect sense.

So the choice would be to either keep myself and my passengers cool or keep my IC cool... I'd choose the latter, but my passengers would probably not be too happy about it

I simply pointed out a flaw in your thinking which you're still not willing to acknowledge. If you're unable to understand pressure differentials and pressure gradients then my comments are falling on deaf ears. To make a blanket assumption that the entire area within the scoop above the IC is equally pressurized because Subaru engineers worked on it is stupid. All I'm saying is that it may or may not be the case but you seem very certain that it is.
Are you next going to tell me that a flat flange downpipe is better or equal to a bell mouth downpipe because the stock one is flat and a Subaru engineer designed it?
Please tell me that you don't have an engineering degree. If you do, let me know which university so I can avoid sending my kids there. My mechanical engineering degree is from the Univeristy of Hawaii and my Master's degree is in Aerospace engineering from the University of Colorado. And yes, my specialty was heat transfer and fluid dynamics. I'm done commenting on this thread.
Ken, please post up results on your findings.
