Ok,
I was finally able to get all the information we gathered into graphs and in a post-able format. I'm on my lunch at work so sorry if this is a bit rushed but I felt like I should at least get the info out to you after so long.
Please people keep in mind that were just a couple guys that are passionate about our Mini's and how they operate. I have no formal experience with intercooler testing or parts testing of any nature. We did this for fun and to get a some basic cooling information from the IC's we tested.
That being said lets get started!
We tested the following Intercoolers:
M7 DFIC V2
AltaV2 Flow Through
Forge
GRS
Stock
How we tested them:
-10 Channel Data Logger recording Ambient, Inlet, Outlet of IC
-ScanGuage II
-RPM's revved to 6800 under full throttle
-We did a full boost run onto a freeway gears 1-4
-The rest of the runs (ranging from 2-3 runs depending on conditions and traffic) were on the freeway between gears 3-4 at wide open throttle.
-We did one final run for each intercooler on a freeway ramp 1-4 gears after the intercoolers and intake manifold were heat soaked. (We soaked each for 8 min)
-Outside is Ambient
-Inlet is air from super charger into intercooler
-Outlet is air leaving intercooler going to the intake manifold
Here is the testbed and intercoolers
M7 DFIC V2 (For some reason our software glitched during the last run as you can see. The colors of the graph switched on us but the data is still accurate)
Alta V2 Flow Through
GRS
Forge

Im sure that there will be questions and believe me, I'll do the best I can to answer them so feel free to ask
I have to say that it was really fun doing this. It was very cool watching the temps and seeing how differently the intercoolers were. One thing came very clear to us early on. Testing is far from easy... so many variables to consider. We tried to make everything as consistent and repeatable as possible.
Anyway, I hope this info is able to help more than hinder. Looking at the graphs and numbers you'll be able to see the intercoolers that actually cooled the air. Pretty cool stuff. I want to thank Peter from M7 for lending me his testing equipment. I also want to thank those of you that let me use your intercoolers! Thanks everyone
