Yeah, see Lancia Delta S4 Group B rally car and Golf 1.4 GT for two (massively different) examples.
To the OP - there's no 'loss of power' from a supercharger - that would make them completely pointless. It's just that because they're crank driven forced induction devices they consume some of the engines initial horsepower.
For example, if you have an engine that, naturally aspirated, generates 500hp and, with the addition of a supercharger, generates 750hp - it may well be that the supercharger uses 100 of the naturally aspirated horsepower to generate the extra (net) 250hp, but you still get a power gain. If you see what I mean.
