10 Diesel Engines Packing the Most Horsepower You’ll Actually Care About

10. Modified Cummins 6.7L — Diesel Madness on Steroids

When diesel fans go wild, things get crazy. This modified Cummins pushes an insane 3,336 HP and 3,642 lb-ft torque — numbers that blow away many gas supercar engines. This build smokes the drag strip with an 1/8-mile time under 5 seconds. Pure diesel insanity.
