The air mass is following the rpm curve because the supercharger is tied to the engine by the belt. Turbochargers can have very quick rise times and then they flat-line due to the wastegate. The Vortech stuff quickly rises to the high efficiency island and then moves across the map with the rpm change until it reaches the max lbs per minute of mass flow before entering the Choke Lines on the map.
You are a smart guy, take a good look at the YSi-B supercharger map.
The YSi-B unit is good for over 1000+ hp and I am sure Mark's customer did not ask for a 1000+ hp street car therefore the supercharger is not running at its maximum potential.
100 lbs per minute is over 1000 hp. The dyno test was at least 200 hp below the superchargers potential airflow capability.

As when spec'n a turbo you should plot the coordinates on the compressor map for the blower as well?
