Some math for you. 20psi gives a pressure ratio of 2.36:1 So even if you could magically through 100% efficiency transform this into a 2.36:1 density ratio, pushing that through a motor that only makes 160hp stock would equal about 377hp. At the crank. As in, not at the wheels.
So what extensive other mods are needed to hit the 'neighborhood' of 450whp?

The tC puts down at 8lbs (not going to be 8 exactly but more like 8.7) of boost between 280-300whp. This is the 2az we are talking about here. The 2011 tC running the 2.5L 2AR has put down respectfully 320-330whp at the same psi (8lbs).
The torque is going to be the same or slightly higher. So, if you run across a tC with 300whp it will have 300wtq to go with it.
When I was on 7lbs of boost on small Evo III 16G turbo I laid down 250whp/260wtq. Later turned it up to 9-9.5lbs of boost and ran a 13.5 @ 110mph in the 1/4 mile untuned on street tires, stock motor still of course.
Then I swapped that 16G out for a 20G and then increased boost to around 11.5-12lbs of boost. Based on other dyno's and taking into account the size of my turbine (which a 20G is still not large by any standard) est. 310-320whp/330wtq. This again, stock motor. The Stock motor will see 350-400whp before internals begin to fail. There are some that have pushed 400-500whp on a stock motor, but of course no point in that, as it's a ticking time bomb. There is enough boosted tC's out there and data to back up my statements.
15lbs of boost on a tC you can expect 380-400whp (not crank). 20lbs of boost is not 377 crank HP.
This is MY tC at 12lbs of boost on a 20G turbo (2.5 inch exhaust, log manifold, stock motor, upgraded clutch).
