As turbochargers have an adjustable wastegate, For stage 3 and above superchargers, an adjustable pulley gear size, where fewer teeth spins it up faster and generates more boost, and would be more fun for stupidly fast grand marshals.
I am kinda working on this concept already, for turbos anyway What will be included is 1. wastegate option for various pressures using a turbo (increases the rpm the turbo can reach but increases temps) 2. Blow off valve option 3. Turbine/compressor blades option 4. Housing options Superchargers could kinda have the same concept
