maybe it eliminates the need for a BOV. instead of having a throttle inline with the intake manifold and having air ram into a closed throttle and flow backwards against the compressor, you close the throttle before air enters the turbo itself and eliminate compressor surge. maybe? :dunno:
Naw, I think there will always be a need for a compressor bypass valve. If you look at this picture, you'll see that it is mounted right on the Manifold:

I think the TB on the compressor housing serves for a quicker reaction time when drawing in air. As a matter of fact, I've seen pics of wastegates mounted right on the exhaust side of a turbo before...crazy shit.
