Keep in mind "if it sounds to good to be true then it probably is." If this fan worked, supercharger companies would not spend so much money on their products.
While this makes sense to us conceptually, it would have to spin sooo fast to actually work. Superchargers are costly because of the RPMs they turn makes them very difficult and expensive to manufacture. At 6000 engine rpms a supercharger might be spinning at 18,000 rpm! That fan would melt at those speeds.
Any chance you saw this advertised on the WB at about 2 am
