If that is the case then tell me why the output of the small turbo is fed directly into the larger turbo. The gate in front of the large turbo must close so that the small turbo can pressurize the large turbo, then once the large turbo spools, the gate in its intake opens so it can suck in more air. I am sure it would take a lot of messing around to get the timing of all those gates right.
