"The supercharger concept in conjunction with the advanced V6 engine provides the best conditions for top-notch performance together with optimum environmental compatibility. Two further comparisons illustrate the unique status of the new Mercedes-AMG supercharged engine: at 109 hp per liter of displacement it has the highest volumetric efficiency of any series-production gasoline engine with a belt-driven supercharger in the world. Its maximum mean pressure – a figure used by engine specialists to describe the absolute performance of an engine – is 17.7 bar (257 psi) at the maximum torque of 332 lbs.-ft. at 4400 rpm. With that rating, this supercharged V6 is the top production spark-ignition automobile engine with a belt-driven supercharger."
"A newly designed supercharger lies at the heart of the powerplant and ensures an unusually high airflow rate. This belt-driven charger is of the helical type with cast aluminium, Teflon-coated rotors. At maximum engine speed these rotors reach up to 20,700 rpm, forcing up to 1200 kilograms (2646 lbs.) of air per hour into the cylinders of the AMG V6 engine. This innovative technology therefore produces a significantly higher charge pressure than conventional belt-driven charging systems. The supercharger in the Mercedes-AMG 3.2-liter V6 produces charge pressures of more than 1.0 bar (14.5 psi), or roughly 30 percent higher than comparable systems."
So....there ia the answer!!
Thanks!
