330 custom supercharged questions

Hi all!
Im AA stage1 user and it is good But since i decided to renew my engine i have idea t make custom stage 3+ setup.

So, im going to use 70mm pulley, who could tell me, how much PSI can Rotrex do? I think i will do engine rev limit at 7200-7500RPM.

I will rebuild (tune) engines head, upgrade oil pump, engines cooling system and I have forget pistons 9,5compression


I want run around 14PSI

And one more question, what fuel pump i should use:
1. AEM 320 LPH Fuel Pump
2. Aeromotive 11142 340 LPH


Thank to all!
