Cummins 6C 8.3-L Dynometer Testing
All of NPD's Cummins 6C 8.3-L Complete Drop-In engines are 100% dyno tested prior to shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm
up cycle; three separate cruise segments simulating light, medium and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a
black light leak detection test with dyed oil, coolant and fuel. NPD uses OEM or equivalent pistons, rings, bearings, valves and gaskets, making sure that this engine will stand the test of time.
