With a Roots style supercharger like the 8-71 on Mad Max’s, if the supercharger isn’t spinning then there’s no path for air to enter the engine. You’d have to implement another full-size throttle body as a bypass to allow enough airflow into the engine when the supercharger isn’t rotating. SCs are very parasitic, hence their use mostly being limited to larger displacement engines that have sufficient low-end torque offset the draw. You could definitely resolve this with a clutched pulley and a bypass throttle-body, the complexity, space requirements, and engineering needed to make it work isn’t worth it. Multi-sized sequential triple turbos are clearly the superior solution to boost at any RPM.
