At first glance that would seem like overkill because if you're running 30 psi on a 3582 alone you'd be making about 700hp although you'd be pushing efficiency.

but in a compound boost setup you'll be closer to a 1.8 as opposed to a 3.0 so you max out power at about 600 still slightly pushing efficiency.

a 3576 wouldn't be able to push the air you need to hit 600 in a compound boost setup.

p.s. one other benefit to note on a compound boost setup. If you were running a 3582 alone on a fa20, you wouldn't hit max boost until about 5500 rpm, where as in a compound boost setup, you'll likely hit the 12-15 psi by about 3500 rpm, plus you'll be closer to max boost much sooner because of the compounding of boost.

Quick Search showed this. Going to do more research on a good calculator.
