Turbo sizing math question...?!

Turbo sizing math question...?!
When doing the math to choose a turbo for a given application, how should I calculate displacement? I found a nifty online calculator at www.smokemup.com (you have to register to have access, but registering is free) but when I choose the built in "rotary" mode the calculated airflows are more than a 350ci V8, so something is borked in their math. I tried 160CID (80x2) but the numbers don't look right when I plot them on the compressor map for a T04 H3... That's what BNR uses for their Stage 2 and they claim full boost at 3800rpm, (12psi) but when I plot the data onto the map you'd be over the surge limit until you hit 4500rpm...
Anybody? ReTed and Evil Aviator I'm looking in your direction...

I'm only shooting for 320RWHP or so... looking for quick repsonse and bulletproof reliability for track days. But why do you say it's too small? Unless I'm doing the math wrong it's too big... doesn't make full boost until 4500rpm and has a lot of good efficiency left way past 8000rpm.
