The setup is awesome, but if I may. The benefit of a twin charge system is that the positive displacement sc produces immediate and massive torque, at low rpm, if the unit is correct size ,and can flow enough air. If the sc was bigger and could, by itself, run enough boost, you would see 400 ft lbs of tq at 2500 to 3000 rpm. It is the tq that you feel with strong acceleration.

The sc does use a lot of engine(parasitic) power to run. Once the turbo spools up(at maybe 4000 rpm), with a large AR, then the sc can be clutched out, and the parasitic loss will disappear. A kenne Bell 2.2L would probably be about right.

No disrespect intended for the car and the system. I have ridden in the car and it is quick and smooth. A bigger sc would make a great project greater.
