What’s the maximum horsepower of a Cummins Engine?

The increased compression ratio of the diesel engine along with the longer stroke of the crankshaft calls for a heavy-duty rotating assembly made to withstand extreme cylinder pressures.

There are several factors as to why the diesel produces that low down RPM torque. There is a combination between the long stroke, boost and compression ratio. The 6.7L Cummins has a bore of 4.21”, but has a stroke of 4.88”. Longer stroke means that the pistons and connecting rods create more leverage on the crankshaft.
