Turbo's run out of efficiency not at just peak boost BUT rather at pressure ratio vs total airflow. IE a T28 may be good for 17psi on it's original Nissan motor at 6500rpm where efficiency may still be acceptable. That same turbo on an inline 6 displacing 3.0L will not be happy at 17psi at 6500rpm.

It will depend on your set up; remember pressure ratio has more involved that just the base size of the engine vs boost/rpm (as measured at the manifold) so it's no good telling me that it is a 4A GE.

Shaft speed is the best indicator for the flow potential of a compressor.
