get a printout of the compressor map for your turbo (exact trim and A/R) if you can. we can do some quick calculations, and see why they used the turbo that they did.
i have another turbo book that i will bring. it is nowhere as good as maximum boost, but it might be helpful in some way.

i would think that the VQ35 is rather efficient compared to other cars. the volumetric efficiency of a crappy old carburated car is about .8 (or 80%), but i would say that the VQ is at least .85 (or 85%). granted, these are only estimations, so there is certainly some level of error in the calcs.

Chad check this out...
https://my350z.com/forum/showthread....ric+efficiency
According to the SAE papers this motor keeps a 100% VE at least to 6xxx RPMs and was measured at 105% at like 5xxx RPMs...Can this be right?

this is definitely possible, with tuned intake and exhaust lengths.
