it is born to remove the so-called “water hammer” owed to the sudden increase of the pressure in the duct between compressor and the throttle body;
the compressor bypass valve or CBV loses that noisiness appreciated by many people;
The pop-off valve is also known as air recirculation valve a or dump valve . It was born to eliminate the water hammer due to the sudden increase in pressure in the duct between the compressor and the throttle body when, with the engine under load and with turbo at high revs, the accelerator is removed or when the butterfly on the throttle body is closed . The air from the delivery duct after the compressor is recirculated in suction before the latter.
The free discharge solutions are only a free interpretation not supported by any technical reason. Of course the recirculated pop off loses the noise that many people enjoy.
