re: Centrifugal Superchargers
I always wondered why would someone use this as a supercharger. You get the spool-up problems of a turbo with very few benefits:
+
Lighter that roots or screw-type
More compact than a turbo, easier to mount, no exhaust plumbing
Slightly more linear response, as it it connected to the crank, but a centrifugal compressor is NOT a linear device (needs RPM to build boost)
-
Draws power from crank (less than roots, but more than screw-type for same boost)
Not linear torque curve
The compressor drive has to step up from 5000 to 8000RPM on the motor to 100,000 to 150,000RPM for the compressor (20:1). Hence, known to need maintenance

Vortech, paxton, and coptech all utilize abelt driven compessor wheel which is similare to the cold side of a turbo. Mustangs have been using for decades. Similar driving characteristics to a turbo. This is not a roots type positive displacement blower. It does add quite a bit of power
