It is a belt driven, fluid geared centrifugal blower for the boost.

^^^ what he said, and people sometimes wonder why dealing with salesman at car dealerships can be so annoying.

Nod, I couldn't remember the product name earlier; it is a Comptech unit. It is a common choice for aftermarket boost for many people. A similar kit is used on the Scion FRS too.

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

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

At least it comes with some sort of investment account. Though it seems odd to sell such an investment for that price. Some sort of credit default swap?

Nothing wrong with centrifugal superchargers particularly on cars with decent low end torque
