I remember that. It had an AMG (mercedes) blower on it. The AMG superchargers use a clutch system for their superchargers (you can hear the belt squeel a bit when it kicks in). As stated, never saw any numbers, just a picture. however, having driven plenty of those I can tell you that those blowers are heatsoaking mothaf&*ka$.
