I just had to point out this particular wonder of a post.
'Cause it's so amazingly prop-worthy. Oh yes, it's SUPREMELY prop-worthy. In fact, it's so prop-worthy that even Brainy has to bow down in awe of Techsalvager's prop-worthiness.

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:
