> If you scale that linearly you still "only" get close to 350 , so you have an idea of how much stress is on this design to push 600 on 2l.

-Removed, I misunderstood the original post, still you can design an engine with more power if torque requirements are low, and they claim 280hp at 2l which is a lot but doable if you don't intent to run it like a roadcar and have infinite budget like with those super/hypercars-

Agree low torque requirements help, which has a lot to do with the rest of the drivetrain, i.e. how you want to actually deliver power and at what speeds.
