In a carbureted application, you would then only deal with whatever driveability concerns are inherent with the blow through application.

Mad Max supercharger was a roots blower. Different animal than centrifugal. I believe there are bypass systems on newer screw type blowers. Admittedly, I'm not well educated on the subject. Was compelled to comment anyway. lol
