Pulley sizing question.

Ok so I just have a couple questions about pulley sizes. This is my first forced induction aplication and my installer is suggesting a larger pulley. We are seeing about 7-8 psi at about 5500 RPM and about 10 at 6400. He would be more comfortable with 8-9 PSI max. We also determined that we are spinning the blower at about 55k rpm at 6400 rpm and accotding to paxton that is the max rpm they suggest and actually suggest not going over 51000.

So I guess my question is simply what do you all suggest? i will be caling Chris on Monday but just kinda wanted to get some feedback

Thanks
