Have you verified that it’s making the expected boost at redline? Have you put it on a dyno to verify it’s not breaking up and pulling too much timing up top? I assume you are familiar with centrifugal superchargers and understand they make little boost at lower rpm (a system that makes 7 psi at 8400 rpm might make 2.5 psi at 4000 rpm) and are revving it out and still finding it to be not that fast.
