About The Engine

The NH-220 is a 12 litre, naturally aspirated engine (no turbo, no supercharger) from 1959 which produces 220HP (164kW) and 606lb-ft (821Nm) of torque. There were versions of this engine made later which had either a turbocharger (NH-262) or a supercharger (NHS-275), but this mod only adds the 220.

If you want the NHS-275 you can find it here and on the Steam Workshop.

The NH-220 was found in trucks, heavy equipment, marine, and as a generator.

This engine was originally known as the NHB-600 and made only 200HP, but in 1959 Cummins had it producing 220HP and decided that was enough to justify renaming it.

Maximum tow capacity is going to be in the area of 50,000lbs, but is somewhat reduced with a steep enough grade.

About The Mod

You will find four horsepower options for this engine in all vanilla trucks and many modded ones too.

The first one is based on official specs (as best as I could find), outputs realistic power for this engine. I highly recommend you try this version out.

1. 220HP and 606 lb-ft.

The next three versions are made-up and never really existed. These are here for people who like the way the engine sounds but don't want to give up the power they are used to.

2. 440 HP and 1,220 lb-ft.

3. 600 HP and 1,650 lb-ft.

4. 750 HP and 2,050 lb-ft.
