which is exactly what I don't understand  - as much as I personally love a NA engine (having several GT3'RS) the turbo engine with it's early torque and these days where you can get any torque curve you want electronically programmed the next step logically for me would be to fill the early/mid-range power-gap and maybe add 20hp on top together with a active aero would make a big difference - 20hp on 520hp to me does nothing....yes. Latest NBR numbers surely come mainly from the tire side and not from the engine (next to a manthey suspension set up maybe)
