Those appear to be good examples on which to base some super back of the envelope ratio type calculations.

540 hp is a better estimate though since the car will likely put down 450 crank, being underrated by 20-30 hp. I'm pretty confident, that the S55 with stock turbos and little to no other hardware changes will reliably permit this, i.e. around 550 hp. Of course the question may be can the ECU be cracked/augmented/circumvented and how long will that take? It certainly begs the question if the "absolutely lag free" throttle response can be maintained at such power levels.
