Help me out with this question, though. IIRC, the max torque of the OM617 occurs at 2400rpm, no?

This has been the claim from M/B..........forever.
However, I cannot duplicate it in any manner. The SD has almost nothing at 2400 rpm and it continues to build torque all the way to 3200 rpm. It's pulling much stronger at 3000 rpm than it does at 2400 rpm.
It's also evident on hills. If I can maintain 65 mph in traffic, it will hold that speed..........but, if it falls to 55 mph, the severe dropoff in torque results in an inability to hold 55 mph...........even though much less torque is required.
I conclude that the specification of 2400 rpm must be false.
