It's a wasted energy turned into power. Why do you think superchargers make less power lb. for lb. Also go turn a supercharger and then a turbo, whether journal or bb, then make your call.

I guess I'm not sure why you would assume I'm referring to a roots style supercharger, how many of us are buying aftermarket roots style supercharger systems? Beyond that, you took the most extreme setup simply to embellish your point.
Centrifugal superchargers are very fixed, they work off of a very linear power curve and build boost progressively.
Of course a turbo is more efficient but I don't recall that being the argument. In my experience I've seen many more, well tuned, turbo cars take out engines then there supercharged counterparts. At least a 3:1 ratio.
