IHC rates them that the DT360 / 466 / 530 can be run up to 3200 RPM without harming the engine but they do state that the hours between major maintenance intervals will be shortened by running it over 2700 RPM.. the closer to 3200 you get the less hours you can count on..
they dont care in ohio either... they are just like stamp stamp print, type,,. ok here is your registration..
Wow! Any chance you can provide a factory cite for that data?
FWIW, the factory ECM config for the DT466 redlines it at 2600 rpm, and the DT530 is set at 2200 to 2400 depending on application. Both engines are way over their torque curves at these cycling rates.
Of course, the tractor pullers spin these motors well over 4000 rpm with 100+ psi of boost, so I'm all ears if there is a published spec that I dont know about.
