I agree with this post. Mr. Sulayem's set up provides boost down low from the SC'er and then once the turbo(s) spooled, it bypassed and turned off the supercharger. Afterall, there is still a limit to how much boost the engine can tollerate. Still, a properly sized turbo system will spool quickly and make adequate boost without all of the extra weight and complexity of keeping the SC'er in place. The greatest gain to be had is not from adding more boost so much as from ellimination of all of the parasitic losses from the supercharger. That is where the big gains are to be had.
The engine will make more power with added boost up to the point that something breaks. The fuel delivery system on the AMG engine is one bottle neck. To go much above 22 psi will take some significant modifications to the ECU system and fuel rail/injectors. Nobody, I know has solved that challenge with this engine due to the digital control of everything thru the ECU making a stand alone very hard to do. The engine is strong and could likely tollerate much more but without a control system, it would not function.
