NHC-250 dyno chart

[VULCANGUNNER]

Does anybody anywhere have a dyno chart for a stock NHC-250 Cummins?

By dyno chart I mean horsepower/torque versus RPM chart.

One that showed volumetric efficiency % versus RPM too would be awesome.

Thanks!

I've never seen a chart. I can tell you that they're rated at 250hp and 685 ft•lbf@1500 rpm. VE really isn't going to help you much on a NA diesel.

You shoud be able to get a factory one from Cummins.

I don't remember Cummins ever releasing a Dyno Factory Chart although they do give you the spec's.

This may be of some help as well: Military Vheicles FWRQST00000169662 NHC250 engine manual.
Also give you the turbo conversion kit info as well.

FYI - if you check that manual out it also gives you the Tubo conversion info as well besides a whole lot of other info.
