I asked the same question.. Ever hear a toilet flush and the water pressure in the place that holds the toilet have HIGH water pressure? And as soon as its done filling the bowl the pipes go BAM! in the walls? Well that could be your superchargers hoses popping off if there no way to quickly alter all that pressure when the throttle plates suddenly close. There is so much pressure it can and will damage your supercharger especially turbos. Its a very important device to a forced induction intake! oh one more thing.. definitely causes a lag idle then back to normal when just reaching stop lights etc.. and sometimes causing small backfires.
