DD15’s can handle 1800rpm pretty easy as the horsepower rating are at 1800rpm. Im not talking about your SALES BROCHURE listing as they are pushing low rpm for maximum fuel efficiency. Look at all the spec from Detroit and you’ll see its a 2100rpm governed engine

I strongly dislike our head engineer for a variety of reasons starting with his treatment of women, moving on to business/economic concerns and he has no clue about the reality of life on the road, but the sob does know his stuff when it comes to design and performance. As much as I want to punch the f'er in the face every time I see him, I do believe what he tells me about engines and their performance. The ahole says that running a dd15 over 1600 rpms causes "damage" (reduced lifetime performance), I believe him.daf105paccar Thanks this. -

The only thing you'll hurt running the DD15 (or most any big diesel) at 1800 RPM is the fuel economy. Typically most are rated for 2100-2200 RPM
@Roberts450 is 100% spot on.
Think about it. If the engineers didn't want it running over 1800 RPM, they wouldn't let you take it that high (and higher) with the pedal in the first place.Last edited: Oct 25, 2020
