low boost pressure
What kind of boost pressure should I see with a vq-s2 with an 8 rib 2.7 pulley and an air to air intercooler? Right now I am only seeing about 8 psi @ 6k rmp. This is the first time I have ran my setup with the intercooler and the new pulley. Previously I was getting around 13 psi with a 2.87 pulley and no intercooler. Below is a list of my current setup
4.6 stroked to 5.1L, kellog crank, forged manley rods, diamond pistons, patriot stage 2 heads, AFM f-52 cams, vortech VQ-S2 with 8 rib conversion, air to air intercooler, vortech max flow by-pass valve, lightning 90mm mass air, 60# injectors, dragon upper intake, typhoon lower intake, accufab 75 mm t/b, steeda boost pipe, bbk valve covers, diablo predator, steeda sub frames, slp longtubes, slp x-pipe, flowmasters, kenne bell boost a pump/boost a spark, aem wide band O2, frpp lowering spring, 3.73's, cobra rims
Also, I need to upgrade my fuel system. I am well over 500 rwhp and my fuel pump cant handle the extra fuel needed. Right now I am leaning out on top end WOT. I was wanting to do a dual pump system with a modified fpdm but no one sells them anymore and I don't know how to setup a dual fpdm. Any inexpensive ways to setup a another fuel pump system? Could an inline Bosch fuel pump work?
Thanks in advance.

Figured out the low boost issue. A inline filter running from the by pass valve to the intake was clogged.

Not a problem. I'm glad I got that part resolved at least.
