Assuming you will not be significantly reducing the RPM limit, you will over-spin the supercharger, exceeding the maximum permissible input shaft speed, and impeller speed also.

The most likely outcome is overheating of the internal components / traction fluid, shortly followed by seizure.

It will also void the warranty on your supercharger.

It will be working outside the areas of highest adiabatic efficiency too, there’s no point doing it!
