It's all about the inter-cooler! The cooler the air the less you have to worry about. The AMG cooling system is poor. I have played with blowers and turbos for 10 years or so and know this for a fact! Any roots style blower usually has poor results with making really HP. A centrifugal force super charger with a big inter-cooler will always work better than a root style blower. I have uploaded some pix of how simple the plumbing would be. These pix are from an LS1 T/A. They have even less room in the engine compartment then we do. I agree with what the Mercedes guy stated above > a bolt on charger with less boost will make more power with the power of cooler air.
