I reckon 230Hp/300NM for the stage 2 is a nice figure to aim for. Especially if they can make it a really flat torque curve with little drop off higher in the rev range
Sadly I imagine the hardware limitation will be the turbo there... It just won't flow as much as you'd want.
Then you're into hybrids, and potentially losing the transition between the S/C & the Turbo
Interesting times though...
