If we follow your illustrated example, there is no chance that what is described (P3> P2) can happen, since there is no combustion here which can increase "P3"? I don't really understand the connection ...
Pumping phenomenon can exist on a compressor independently of a gas turbine, what the § Pumping compressor.
The link is that a compressor is designed for a certain application domain (flow, upstream / downstream pressure, temperature, speed etc ... when fate briefly in his field (Modified by a wild, brutal winnowing etc. ...
) Can be found pumping.

Nothing to do with the system of which I speak, which consisted in packing the turbo during the phases of "lifting the foot" so as not to have to accelerate the whole to the resumption of the throttle.
I found the "Aero" image that matches
These pre-swirl vane obstructs the air inlet to the inlet of the first compressor stage to limit power of the compressor part of the consumption.
By cons I have not found the car image with the device (can not be so common outside the competition
)
