I figure if it were that much of a big deal MB would have done it from the factory it's only a line or 2 isnt it?
BUT in saying that a few guys have seperated there systems and ran like a trunk mount system and fill it with ice or have ice around it on track days now I do believe that would definatly help.
it most certainly helps. the hot coolant from the engine isnt being run thru the i/c. also the i/c system is low pressure and the engine is high pressure. so the sep. is cheap and an added bonus
the rear tank only helps if you are draining and refilling with ice. no matter how big a system you run, eventually all the fluid gets to the same temp as the i/c and the supercooler can only cool so much before its heated again. the more fluid just allows you to take longer to reach that point. then you have to consider the weight vs temp advantage.
brianbrave has a ton of info on this subject. check his posts.
as for running better when hot, if your just running test and tune you can stop at your convience. if your bracket racing or autocrossing for long times you will have s/c shutdown. in the us there are times when you will be hot lapping at the 1/4 and no time to cool down . then the iat's will rise drasticly
