+1, ohonesaz.

 IIRC, Vadim fabricated an SLR-style intercooler while at evosport. I’ve not seen a massive heat exchanger or FMIC in front of an M112 from them, but that doesn’t mean it hasn’t been successfully done. It has. He has since moved on to VRP. However, these photographs of his prototype are still on the MBW server:

My worthless perspective on why Daimler Chrysler went with the intercooler and heat exchanger location setup they did was merely to minimize packaging concerns. For them to tuck the intercooler in the valley meant that virtually no modifications to the existing W170/203 chassis would be necessary to shoehorn in the AMG powerplant. A heat exchanger, cheap fluid pump, and some rubber hoses were all that was necessary to prepare the engine bay for ~350 horsepower. I don’t believe it was related to airflow across the radiator which, as you’ve noted, is already quite obstructed. Nonetheless, my coolant has never approached overheating even during summertime track sessions in the California desert.

To have plumbed a FMIC or heat exchanger of sufficient BTU strength in order to cater to us incorrigible gearheads would have necessitated far more chassis variations from the lesser variants, and was therefore promptly nixed by the bean counters. imho, of course.
