Subaru TMIC vs. FMIC testing Interesting stuff.

"There is just not enough ambient air flow for TMIC's to work properly under heavy load. With the PERRIN FMIC installed, we would see intercooler outlet temps peak to 105F and by the 4th run it would peak to 110F. Yes, the highest Intercooler outlet temp we saw was 111F, this is compared to 158F we saw with the PERRIN TMIC. The below data is taken from the 3rd run of both the intercoolers with roughly the same time between runs."

Also, regarding TMIC efficiencies from Vishnu tuning:

"What we've learned during our cooling efficiency testing is how important it is to have a top mount IC properly ducted/sealed with NO portion of the core "sticking out" of the rubber surround. Effective cooling efficiencies (hood closed, running at 60mph) would drop by as much as 10-12% depending upon how much of the core wasn't ducted. To improve real-world cooling, we actually shrunk down the IC size throughout the course of the developement in order to make it seal perfectly with the STi duct/seal. Properly ducted, we could then increase the density of the external air turbulators to improve cooling while still maintaining a good ambient airflow rate through the core (thanks to the duct). And without any portion of the core going unducted, we didn't introduce any interheater effects, which occur when aluminum sits under the hood without ambient airflow hitting its surface.

This is one of those products that cant be tested on the dyno very accurate since you are mainly testing its thermal mass. In that case, more is always better. But on the road, with the hood closed, your also testing aiflow rate through the core which affects every aspect of IC performance apart from pressure drop (which is easily tested on the flowbench)."

What about using a water/meth kit on either the TMIC or FMIC. That helped a friends car by 40hp and that you can set it for a certain boost level. Maybe you could put in a temp switch and a boost switch (just an idea if room is an issue). Here is also something I also learned from a bunch of Turbocharging books, if you use a scoop or front opening in the bumper. You must use a smaller opening than the surface area of the Intercooler/Radiator. This will make it more aerodynamic/cooler air charge
