I've seen rods pop at 90hp... I've seen HDi rods blow well before 200hp.
Just because the XUD11 has meatier rods, wouldn't trust them any more than XUD9 rods... They'll have the same cheesy metal in them, it's a forging fault rather than a size problem, adding meat to them won't help - only increases rotating mass, therefore how much it's got to swing off the end of it - the XUD11 crank is accelerating and decelerating the components faster and harder, making for a less rev happy engine and at 21:1 or so compression ratio, that's the last thing you want.
Look at more modern Diesels coming along, Subaru Boxer diesel - square engine at 86x86...
