How much horsepower does a 5.9 dodge diesel have?

The horsepower of a 5.9L Dodge Cummins diesel varies significantly depending on the year of manufacture and specific engine modifications. There's no single answer.

Generally, the factory horsepower ratings ranged from approximately 215 hp in earlier models to around 250 hp in later versions. However, many owners modify these engines substantially, often resulting in significantly higher horsepower figures. Therefore, without knowing the year and any modifications, it's impossible to give a precise horsepower figure.
