you'll need at least a 3.8 pulley to get to 9 psi iirc.

Your results may vary, but I was making 9.5 PSI with the K20A3 crank pulley & 3.8" SC Pulley. Just changing to the k24a4 CP upped me to 11.5 PSI. So you may be able to reach 9PSI or more with the k24a4 CP and 4.0" SC pulley.

I may try the combo k24 crank pulley and the 4in blower pulley
Before buying another one

Thanks to the OP for starting this thread. I haven't been able to find anyone that still makes a 3.8" pulley and I want more boost, so I may go the same route.
