Have they broken through the 500 hp barrier yet?

The highest dyno chart pic I've seen posted on mersuforum.net is one of a 190D with an OM603 (not OM606) churning out 482 hp screaming at 5700 rpm. The fact it produces this power at that rpm with plain diesel fuel is just unbelievable.

EDIT: (I bet that blue W124 with the OM606 is close, perhaps even has greater power)
