Why would it be very difficult? If I were to buy a salvage yard blower, how would I tell if it is in good shape, or on its last leg? I understand the obvious bearing wear which is easy to detect, but how do I tell if the rotors are worn, or if it will build normal pressure? Yes, I know that the supercharger just moves air and doesn't actually compress it, but you get what I mean.
