There's a website called SquirrelPF.com that has a pretty handy useful turbo calculator. I punched in a couple numbers you can see here = 200 hp, start spooling at 1800 RPM, maximum boost at 2500, and a 6000 RPM redline so we don't fry eggs on the intake manifold. Then I plotted the resulting airflow on a GT1544:
