Lifters aren't just affected by RPMs... Inlet and Exhaust manifold pressure will play a big part in doing them in...
Also with regards to engines popping, yeah, we've all seen stock 90hp XUDs pop rods just going up the road, more power will obviously affect this... I'm not saying the 2.1 is weaker, it shouldn't be, but I know people who've popped HDi rods when everyone said they'll stand up to it... I'd put money on XUD11 rods being made out the same stuff and I bet you they have the same issues as the 1.9s with random rod blowing, it's just masked more since they're beefier engines as standard, the hike of 20hp isn't enough as standard to make them blow for the beefier bits in, but the theoretical more power that should be able to be extracted from them, I wouldn't be surprised if eventually you saw the same issues... The problem is one engine at 230hp not blowing isn't enough to say conclusively that the 2.1s DON'T suffer from rod failure... My XUD9 has probably done the most amount of miles at over 280lb.ft torque, yet my engines fine, but I know people with OEM pumps at 90hp who have blown them cruising on the motorway...
Don't get so defensive - christ almighty...
