So, in that sense, lb for lb of boost, a turbo does "generate" more power due to it not soaking up as much power to generate that boost pressure.
In that sense, a s/c application does show less "gain" at a given boost level.

You are absolutely right. Granted newer sc's eat up less than old ones, it still does make a difference. In theory, all other things being equal, they produce the same. However, in practice, the SC unit itself does rob the engine of power and that means that you are correct. I forgot about that and stand corrected; a turbo will put a little bit more power down per psi than a supercharger. Good post sir.
What I was trying to get at, that's been bothering me a bit is this whole turbos are so much better than superchargers attitude when they really do the same thing and produce almost the same power.
