I will look at HPA, house of boost and brute though thanks.

I don't see how this is possible (stock engine???) on a 4.5 (upper) pulley my D1X makes 7 PSI at 6800 RPM, maybe 8 PSI at 7100 RPM. built engine stage 1 cam. 
With a 4.0 pulley it is about 12 PSI at 6600 RPM same engine. Both with the procharger standard lower pulley.
I mean it is only at 2/3 speed with a 4.5 pulley (I did the cals several times you have to search).
stock damper. I would be worried that you add on crank pulley may not fit aftermarket dampers. (Procharger would know). I assume you have the old style kit that has a separate crank pulley. If not Yeah, I would assume an UD crank pulley would work.
