Well, you can actualy put it anywhere after the compressor. You just need a reference pressure from the intake manifold to actuate it.
There have been arguments on were to put it on custom systems and if i'm not mistaken it usually ends up nearest to the throttle body to avoid as much compressor surge as possible. The nearer to the throttle body it is the faster it can dissapate the back pressure from the plates closing.
Please correct me if i'm wrong Warr...
