2008 Dodge Ram 2500 6.7L Cummins - Diesel Power Challenge 2014 Competitor

Mike McGlothlin
Jun 24, 2014
Hailing from southeastern Canada, Danick St. Pierre resides more than 1,700 miles (2,800 kilometers) away from where Diesel Power Challenge is held. But that wasn't the only traveling he did in the days leading up to our event. A week before Danick was due to sign in at DPCX, he took a flight to Indiana to retrieve his 1,200hp 2008 Dodge Ram 2500 from Fleece Performance Engineering, the shop that built much of the truck. Then, it was off to Florida to be custom-tuned by EFILive ace Ryan Milliken of Hardway Performance. Before leaving the Sunshine State, Danick made a stop over at Sun Coast Converters, picked up some transmission parts, and headed northwest to compete. All we can say to that is that Danick must be one determined individual. He effectively traveled more than 3,000 miles to get here!

Built B Series
A balanced and blueprinted rotating assembly is at the heart of Danick's high-powered 6.7L Cummins, and it was spec'd, machined, and built by Fleece Performance Engineering. A competition long-block features Carrillo rods, ceramic-coated pistons, 14mm main studs, a 188/220 cam from Hamilton Cams, and fire rings that protrude into both the block and head. The Fleece competition cylinder head called for 110-pound valvesprings and a port and polish job and is anchored to the block via ARP's Custom Age 625 head studs. A high-flowing Banks Big Hoss intake manifold brings more air in, and a T4 Steed Speed exhaust manifold gets spent gases out.
Stacking horsepower on top of the bulletproof long-block began by putting the common-rail injection system on steroids. Exergy Engineering spec'd a set of 5.9L-based injectors, complete with 150-percent-over nozzles. Fleece installed its dual CP3 kit, and a 150-gph FASS fuel supply system gets things rolling. This kind of mega-fuel recipe puts enough fuel on the table to make well north of 1,000 rwhp with the right amount of air, which brings us to the turbos…
Competition Compounds
Even in our wildest dreams, we never would've believed an S475 could be the high-pressure unit in a compound turbo arrangement on a street-driven truck. Nevertheless, the team at Fleece uses one to get a massive S591 atmospheric unit turning in its competition compound system. Spot-on tuning and a correctly stalled torque converter will be key items in making the giant turbocharger configuration driveable at elevation. Thanks to Fleece swapping in a 5.9L ECM during the build (in order to spin high rpm), EFILive tuning guru Ryan Milliken of Hardway Performance should be able to make the truck both driveable and a top performer in all events.

Battle-Ready Transmission
As for the transmission, the 68RFE went by the wayside and a full-billet 47RE replaced it. The four-speed automatic's proven track record behind high- horsepower builds was the primary reasoning here, and a host of Sun Coast internals make it as battle ready as it gets. Sun Coast's OM3GA input shaft, billet intermediate shaft, 29-spline output shaft, and a M3GA drum reside inside the case; a triple-disc torque converter harnesses the engine's power; and a PCS-controlled valvebody handles all shifting. Ryan Milliken took care of the TCM tuning.
We picture Danick finishing consistently across the board at Diesel Power Challenge. To expect anything less out of this crazy build would do all of you a disservice. There is always a special enthusiasm that accompanies our Canadian competitors, and Danick is no different. The way we see it, if he's willing to travel the farthest, he might just be the hungriest for the win…
