Thanks guys. 
I was still hanging around a bit when Evosport was teasing us with the promise of an SLR style i/c system. What a joke that was...along the lines of Supersprint charging over $12k for full exhaust in the early days! It's a shame a real solution hasn't been made yet.

There's more to do than just remove the dividers. You can cut back the return opening to make it look like the inlet side and smooth it out. You can also turn the stock core into a split design and run inlets in and out of the rear to make sure the entire core from to rear is getting 34 degree water on a 1/4 mile pass.

Those holes that are drilled doesn't work very well. All that material needs to be removed and then smoothed out and the outlet can be open up larger until where the threads starts. A friend and me spent the better part of a week cutting core open and trying different things and testing them.

Cut the side/end tanks off the intercooler and remove the little chamber walls in there and weld the sides back to the core. I assume this is what amgrocket is referring to.
Some people in the past may have figured this out and tried to keep it a secret selfishly instead of helping the community out. I cut a spare intercooler apart when I was going to make a top mount setup and found these chambers that made the intercooler a "triple pass" setup. The coolant flows in and then goes back and forth 3 times before it exits the intercooler. Water/coolant that is getting hotter and hotter and hotter is not doing any good to cool the charge compared to if it passed through once.
If you were to make it a single pass through design by removing those little chamber walls integrated in those side tanks you should have an improvement.

No idea, there are double pass but triple seems a little ridiculous. It is going to kill the flow of the system and also have the heated up coolant/water problem trying to cool the air.

The only thing I can think of is that the engineers designed the entire system for the original HP level that this car had, and based on the limitations of the stock IC pump for flow (CFM). Going with a triple pass solution might just have been their way to insure that the entire IC had very consistent temperatures everywhere... No hot spots, no cold spots.
Just a theory.

AMG is well aware of the "world of tuning." During one of my visits to Affalterbach I asked why would AMG allow such a horrible exhaust manifold to be used? The response was: "We leave that stuff to the tuners."

Only got a few passes before the pulley took a dump but the highest i seen was 112 on a back to back run. If i started a run at 34-35 degrees it wouldn't make it to 100 degrees by the end of a run. Didn't have a lot of data to go on but i know it works far better than stock. Every 1 degree you can lower IAT's is worth 1hp.

If their response was genuine we'd have better access to ecu maps!

I believe it was genuine. As for their ECU maps, it is generally recognized that technology is the most fleeting of all resources, AMG, and others, always try to protect their intellectual property as best as they can.

I call BS, a decent set of headers will do nothing but allow these cars to be as efficient as possible.

You received a better answer than I got. I made the same statement to our guide at AMG last month and he said "the engineers used did the best they could to maximize performance and reliability"

Whenever I go to Affalterbach I just drop in unannounced. Usually one of the folks I know will take me around. I believe they have always been honest in their "off-the-record-comments". All they ever asked of me was not to post some of the photos I had taken in restricted areas.
