Seeing as centrifugal superchargers make boost as a function of RPM, you would need a pulley to spin the s/c faster so it can make max boost at 5500 rpm instead of 6500 rpm. With a proper tune, there should be no reason why a 5.4 couldnt handle boost as well as the 4.6 does, even with stock internals.
