A Work Truck-Turned-Quarter-Mile Monster

When Devon Evans bought his ’05 Ram 2500, he had no intentions of bombing it. He didn’t even know what bombing meant, nor did he have the first clue on what diesel performance modifications were available; it was supposed to be a work truck for his commercial and oil field consulting company, Evans Consulting. For eight months, the truck remained stock as it took Devon around the province of Alberta.

One day, Devon was merging onto the highway when a big black dually passed him and his Dodge like they were standing still. That black dually was covered in NADP logos. The next day, Devon was busy installing an exhaust system and cold-air intake on the Dodge, which lasted about a month. This time, it was a gray Dodge that left him in the dust as soon as the stoplight hit green. The silver truck also had NADP stickers and Devon had enough; he called the number on the Dodge and demanded his truck perform better.

The Common Rail has made 825 hp to the rear wheels on fuel only and 925 with a shot of laughing gas.

Devon went down to NADP and picked up a programmer to complement the intake and exhaust he had already installed. Within a month, that still wasn’t enough power, which lead Devon to sit down with NADP owner Barry Voltner and head mechanic Matt Adams to put together a game plan. That’s when the Dodge would undergo its first of many renditions, and have Devon spending almost as much time at the NADP shop as he did at home.

One of the first things NADP suggested was to lay the groundwork for the drivetrain with one of its bulletproof automatic transmissions and torque converter. The stock injectors were then removed, being replaced with 50-hp performance squirters, while breathing was improved with a 6-mm turbo and Banks intercooler. That combo, along with a FASS 150 system to help keep up with fuel demands and a Smarty tuner stacked with a Dr. Performance module, was good enough for 12.30 quarter-mile times. Once again, that would only keep Devon happy for a limited time.

Matt pulled the motor and began improving things like the cam, head studs, valves and new bearings. The factory cast-iron exhaust manifold was replaced with a tubular exhaust manifold, and a 66-mm turbo was swapped out in place of the 62 mm. While the charger still pushes air through the Banks intercooler previously installed, now it also goes through a Banks High Ram intake manifold while sucking in air through a custom NADP intake.

A pair of 6-inch black stacks neighbor the Zex nitrous bottle that feeds a single-stage system.

With the head off during the rebuild, Matt cleaned up the exhaust side with a mild port job. Devon also had the valve cover custom-painted with flames, and a ghost NADP logo before the engine went back into the truck. Once the Cummins was back between the fenders, a 5-inch exhaust system was built, which leads to a pair of black, 6-inch stacks coming through the bed of the truck.

The truck was quick before, but Devon and the NADP crew knew it was going to be a lot quicker down the track with the new setup. To avoid getting kicked off the quarter-mile by officials when the truck hit roll cage territory, it was fitted with a cage certified to 10.0. Devon also jumped on the opportunity to install a Kirkey racing bucket that previously sat on the passenger side of the Drever Family Racing Dodge built by NADP. An SFI-approved harness from RCI was also installed to keep the Ram legal. Just inside of the tubing for the roll cage are Auto Meter Phantom gauges to monitor transmission temps, EGTs and boost.

Helping put the power to the ground through a set of 305/50 Falken Ziex S/TZ04 tires mounted on 20-inch chrome RPM wheels is a set of traction bars. Outside of the wheels, not much has been done to the outside of the Dodge, though Devon did decide to add smoked taillights and a smoked third brake light, all from Recon. On the rear is a Rumble Bee-style stripe with a Cummins logo, too.

Devon started the 2009 Division 6 NHRDA race with a win, running 11.6 on fuel only. He then took the Dodge to the Camrose, Alberta, 100-foot shootout, where it beat competitors like 1,300-hp fully built drag cars with is 2.29 time to take home fastest competitor. Since then, the Cummins received a single-stage Zex nitrous system and has run an 11.2-second quarter-mile. On the dyno, the Dodge has made 825 hp on fuel and 925 with the bottle.

You’d think all of that would be enough, but Devon isn’t finished yet. Down the road, expect to see the 3/4-ton with more suspension modifications, a few hundred pounds lighter, bigger single CP3 and a new turbocharger setup. It’s a pretty good to-do list for someone who didn’t know the first thing about diesel performance until he got smoked by one.
