i'm no expert on super vs. turbo, but someone can always correct me on this. anyway, the way i understood this was, turbos have lag, which can be minimized but will always remain. the engine runs almost like an NA car as rpms rise until the turbo spools and when its about done spooling, the compressor is spinning fast and hard enough to push some serious air so the boost kicks in, and by boost, we mean that nice kick in the pants from that significant power gain....the supercharger, on the other hand does not need to wait for a build-up of exhaust gas pressure, the crankshaft will turn the compressor immediately as rpms rise, so you get virtually no lag in power, but here's the catch, the power is delivered linearly....so you don't get that sudden kick in the pants...you get an engine that behaves like a more powerful NA car....the other catch is that the "boost" is limited. the reason for this i suspect to be because you can't change the gearing for the supercharger as rpms rise, so each engine rpm will have a set compressor rpm, and i'm sure there are other reasons....so you reach peak power gradually, which is going to be less than peak power with a turbo, and also why it feels like you don't get any power until redline with a supercharger vs. a turbo....so long story short, superchargers are more responsive to throttle, have a steady, linear power delivery, but the trade-off is less peak numbers than with a turbo setup...
