I am really interested in this thread and pictures even if its a joke as i find "twincharging" the ultimate way of building a high power, responsive engine.
I used to own a Ford Escort RS Turbo wich had a small 1.6 litre engine with a T3 turbo, boosting from 3000rpm. Power is a really great thing, controll over it is a knother. 220bhp in a 1800lbs car is preety fast, still throttle response was on the laggy side even at high rpm's, as well as power controll. The car was a FWD so it was really pushing the driver in terms of throttle controll.
On the other side, compressors use large amounts of power off the cranckshaft providing exellent throttle response, unfourtenetly the engine losses its "puff" at higher rpm.
I think running the system in a serial configuration is a waste, unless in very high power applications.
The systems needs to be sequential with a electromagnetic clutch on the compressor and a set of valves controlling the air flow through the system, very much like the VW Twincharger system wich i find brilliant.
I think its possible to do using pneumatic actuation only with a few tricks. Still, some computer controll wouldnt hurt
