On the way to Seattle from Vancouver this morning, my pump failed (I can't imagine life without the supercharger).

Once I got to Seattle I immediately ordered the Johnston IC Pump from Let Motorsports and I'll take into an MB tuner shop for replacement as soon as I get the part but here is my question...

Is there any damage being incurred to the motor with the supercharger not being engaged? Is it OK to drive the car back home?
