I personally know a couple of folks with supercharged 911s. Both are fellow PCA members.
One is a 911SC with an SOK whipplecharger.
The other is a 996 with an Evo centrifugal unit.
Both are torque monsters.
The 3.0L SC puts out a conservative 260RWHP at 0.5bar on pump gas and feals like it has a small block Chevy out back. The 996 puts down 350+RWHP and can chase down twin turbos.
Roots type blowers are instant-on while the centrifugal units feel more like a turbo.
