Read that thread. You don't have to do all the math, just calculate what your engine will flow for CFMs at atmospheric pressure at say 7000 RPMs, then look at a 14b compressor map. See what the highest point is within the efficienct area (the little island like area on the map.) If you get outside of it (ie too much pressure not enough flow (surge), or too much flow not enough pressure (choke)) then then it will just be blowing hot air, or you could be overspooling the turbo, not good for the bearings.
