Just out of curiosity, what was your set up to reach 16 psi? I am limited to 93 octane so my next step may be methanol Injection. I was also looking into the Z1 intakes but haven't seen that much discussion on them. Any input greatly appreciated as always.
I had the 9lb pulley, 3.47 jackshaft pulley and 3.00 sc pulley. I was just under 17 psi with that set up. I had to run e85 at that psi but since I also ran a wastegate, I could turn the boost down when I ran 91 octane (I ran flex fuel). You don't have access to e85?

You're wondering about the Z1 ported upper and lower intakes? I don't think you're going to gain much with them.
