Still no answer on dropping a drive belt for a super charger.
If there is a drive belt on a supercharger than it is probably a blower of some sort.
If a blower stops spinning, so does the airflow thru it. No air/airflow, then combustion will be super rich/non-existent.
I have not heard of anyone devising a blower bypass to get naturally aspirated air into an internal combustion engine. Help me out here??
A turbo can have its wastegate lowwered to such a low release pressure that it can effectively be turned off, but why bother having it then?

1. Thanks that is the correct answer.......there is no air flow thus you cannot just drop a belt.
I had heard of several companies years ago that had an electric clutch and at the flip of a switch could free spool teh supercharger and at the same time open up an inlet for free breatching but I have not heard anybody doing that these days I think because of reliablity problems. If anybody is doing that anymore please let me know.
2. Superchargers are always physically connected to the crank thus they have parasitic drag and therefore hurt fuel economy. Turbos can actually increase fuel economy during normal driving. What you have to watch out for is the incredible eat generated from the Turbos due to the exhaust gases. With a good design Turbos are better for fuel economy during normal driving.
3. Turbos are easier on powertrains than superchargers because they bring on power easier. Turbos usually do not have boost at 2K RPM while a supercharger can have boost as low as 1.5K RPM.
I don't understand... did you know the answer in the first place and were just testing everyone or asking an actual question?
