Stage one boost is instantly on from the positive displacement supercharger.
Stage two is once the turbo spools, feeds into the supercharger, gets compressed again, then enters the intake. This creates massive intake pressure, and since the turbo doesn't even have to be that big, very quickly.
Size matching them is apparently a little complicated though.
Diesel trucks can do it with small and big turbos.
