You get a twin screw blower and all bets are off. You'd be way up there in output. The twin screws build pressure in the case and are a whole lot more efficient than even the Gen 5 M90.
There is a kit out there for the Grand Prix called the Whipple charger and its making some insane levels of boost. There are a few in the community that already have them but I have heard from them that tuning is a bear.
I saw a twin screw blower on a GTO and that sucker was just stupid fast and had a VERY distinctive sound to it. It was unmistakeable that the car was just going to kick some butt.
