I wouldn't advise running without the supercharger on an L67 for any extended period of time, or any short period of time in an RPM range that the car would expect to hit boost.

I had to limp my car home without the blower attached after a topswap becasue I threw a tensoner pulley down the track, and I had to keep it below 1/3 throttle so it wouldn't try to hit boost.

Why don't you just fix it? Even if the blower is completely gone, you're looking at what $200 for a gen3 and gaskets...
