Looks like at even ~7psi it'd be flowing as much as 500cfm albeit with not great effeciency correct? There's nothing smaller that could really flow enough air to support say ~400 wheel at a max of ~9psi? hmmm

Yea its a tough call for the stock vq motor going the single turbo route. I think 8 or 9 psi 1.6 bar on the chart would be where you need to run keep in mind you still run 74% efficiency which is very good as well as a fmic will really offset the efficiency anyway.

I think thats a catch 22 situation with the vq block. The engine is fairly large so it demands a good deal of cfm to feed it.

this is exactly why greddy has such large turbos for their TT kit. They need to run that big a turbo to get the cfm output that is needed in low boost pressures.

Im very interested in more info on the turbonetics kit as really the only reason i can see to run a single turbo on the 350z is to have a lower price of the turbo kit....other than that i cant see why twins wouldnt be anyones first choice!
