The supercharger design for generation 18 is below. The design must be optimized but the present design is very promising. The goal is to purge and charge the combustion chamber for each stroke. At full throttle, the boost should be close to 5 atmospheres and less at low throttle. After charging, the energy in the supercharge can be recovered. Optimization involves varying the supercharger diameter and clearance volume at BDC. The calculation also look at the combustion port velocity.
