$100K SECOND-GEN
Leaving his VP44 and P-pump knowledge in the past, Kenneth Donkersgoed had Freedom Racing Engines piece together a stout 6.7L Cummins common-rail for his ’02 Dodge. The balanced and blueprinted power plant is graced with 9/16-inch main studs, Carrillo rods, Freedom’s fire-ringed Performance series head, 14mm head studs, and was topped off with the ’03-’05 marine valve cover that’s visible here. Along with overseeing the entirety of the truck’s build, Fleece Performance Engineering’s Jake Richards executed the common-rail swap to perfection.
Ironically enough, dropping a common-rail Cummins into the old Dodge required Kenneth to run one of Fleece’s second-gen turbo swap kits to achieve the kind of power he was after. The charger spec’d out for his build is an S400 with a 63mm compressor wheel, an 83mm turbine wheel, and a .90 A/R exhaust housing. The S400 breathes through Fleece’s 5-inch ManTake cold air system and is efficiently driven thanks to a T4 exhaust manifold from Steed Speed.
Making use of some of the most proven fuel system parts in the industry, a Fleece PowerFlo 750 CP3 supports a set of 100-percent over injectors from S&S Diesel Motorsport. While the single 10mm CP3 stands no chance of supporting an all-out effort from the 100-percent over injectors, by running an injector that’s larger than what’s needed, stock-like injector duration can be commanded. This means the truck’s 750-800hp is achieved without the engine having to endure excessive EGT or stress to make it happen.
