The rotors have to be "timed" to leave proper clearance between the rotors at all times.

So playing with "timing" of the rotors relative to each other is impossible.

Perhaps you're referring to playing with changing the "overlap" between when a rotor is open to the inlet and to when it seals against the side of the case. Like-wise with the outlet.
