You can also plug it. Those of us that opt not to recirculate the DV have to plug it.
Do you have exhaust? I am trying pick out a pulley for my ap2 with novi 1200. From what I have seen, there is a huge variation between pulley sizes and psi.
I thought I had cracked the code, figuring SOS's chart was roughly 2psi on the low side. But your 9.5 max on a 300rpm bumped up revlimiter means SOS's chart is nearly 1psi on the high side.
Thats a +/- 1.5psi when choosing a pulley and that is tarded huge. So lets say you have an efficient exhaust system. You run a 4" 10psi pulley at 1000ft which should be 9psi. You bump it 300rpm for an additional 0.3psi. I can see why you are making 9.5psi. That makes sense.
What doesnt make sense is others on a stock exhaust will run 11-12+ psi with a 4 pulley @ 1000ft. Did their s2000s go gerbiling and have them get stuck in the Cat? The only reason for this psi variation that I can come up with is exhaust efficancy.
I bought a header and a test pipe to drop my psi by 1 at their set up. Meaning I bought those parts to run around 11-11.5psi at 8300rpm @ 1000ft.
I dont want to run a 4" pulley though, I want to run between 13.0 and 14.5psi at 1000ft with 8-8300rpm. So I dont know if I should pick the 3.6" or 3.4" pulley. This pulley/psi variation has boggling and bothering my mind for the past six months. My marriage is suffering from it.
