A lot of folks get into and then back out of this sport in that amount of time—but not the Whalen’s. Throughout the last decade, and year after year, they’ve remained determined to put their truck in the winner’s circle. It all started in 2007 when the family brought home this ’01 Dodge. Already having been converted to a dually, it was essentially purchased as a way for Rick Whalen to feed his son Ryan’s thirst for sled pulling—yet keep him from hooking his daily driven Duramax to the sled. In the years that followed, Ryan gradually began sharing the driving duties with his younger brother, Daniel, who would eventually take over the reigns. “Concrete-filled, 6.7L-based cast-iron block” Over the course of the last nine years, the Whalen’s have seen the explosion of engine, turbo, and fuel system advancements firsthand—with their own engine combinations doubling in horsepower during that time. Throughout the years, the truck’s powertrain, chassis, and cosmetic appeal have all undergone major changes as well. By 2009, the P-pumped 24-valve Cummins was yanked in favor of a 12-valve, and by 2013 the truck was graced with an 8-foot bed, a longer wheelbase, and a fresh paintjob. Today, the truck sports a set of cut tires, a deck-plated Cummins, and makes more than 1,800 hp.Subscribe Our Weekly Newsletter One look under the hood of the Whalen’s ’01 Dodge reveals a true work of art. From the Scheid Diesel polished billet-aluminum runner intake manifold to the Keating Machine billet one-piece valve cover to the powder coated intercooler piping, it is very easy on the eyes. A nasty, P8600 P-pump from Scheid Diesel is in charge of sending fuel to six 5 x 0.030-inch triple-feed injectors. The pump utilizes coated 14mm plungers and barrels, a coated quick-rate cam, and an Ag governor that allows full fueling past 6,000 rpm. While the pump is easily capable of flowing more than 1,000 cc worth of fuel, it’s currently set at 750cc. 6.4L Cummins At the heart of the Whalen’s second-gen sits an engine built to both produce and survive big horsepower in the Pro Stock diesel truck class. Assembled by Flynn’s Shop in Alexander, Illinois, the 391 cubic inch Cummins incorporates a host of proven parts from Scheid Diesel. Starting with a concrete-filled, sleeved cylinder, 6.7L-based cast-iron block, a factory 6.7L crank is utilized and secured via a girdle and 14mm main studs. Filling each cylinder is a billet-steel R&R connecting rod and valve-relieved Arias piston combination. Further strengthening the block—and a major factor in making the engine so reliable—is the employment of a 1-inch thick deck plate up top. A full, race-ready 12-valve cylinder head with extensive porting, oversize valves, competition valve springs, and chromoly push rods channels fresh air and spent exhaust gasses in and out of the cylinders. Accommodating the P8600 to the 6.7L block is a Scheid Diesel billet-aluminum front gear housing cover, which also allows a gear driven fuel pump from Daryl Saucier Racing (DSR) to be put to use. The billet-aluminum DSR pump sends a healthy 50 psi worth of fuel pressure the P-pump’s way. Fuel System On Steroids With the engine sporting an ultra-low 12.5:1 compression ratio, plenty of fuel can be injected in-cylinder. Sending an exuberant amount of fuel volume to the injectors through oversize 0.120-inch stainless steel lines is a 14mm P8600 injection pump from Scheid. A gear-driven DSR fuel pump ensures 50 psi worth of supply pressure is sent to the big P-pump. A massive set of 5 x 0.030-inch injectors (also from Scheid) utilize a triple feed design, heavy-duty SAC nozzles, and a custom spray pattern. 3.6-inch Smooth Bore Turbo While the engine was equipped with a 3.0-inch inducer turbo for years, recent Pro Stock rule changes led to a 3.6-inch turbo being permitted in 2016. The catch is that no map width enhancement groove can be present anymore, which spawned the creation of a unique charger from Hart’s Diesel. The massive turbo incorporates a true (“smooth”) bore, proprietary 3.6-inch inducer compressor wheel, and a custom ball-bearing center section. Without a doubt, the smooth bore turbo rule eliminates a lot of the gray areas that used to exist in the class, simplifies the tech process, and—thanks to the upsize—allows trucks to make even more horsepower. Hart’s Diesel built the massive turbocharger that feeds the engine. It features a custom, ball-bearing center cartridge, T6 flange, bolts to a Steed Speed T6 exhaust manifold, and makes 60 psi of boost. Built to meet the new 3.6-inch smooth bore turbo rule for open driveline Pro Stock diesel trucks, no map groove exists on the turbo. Although First Place finishes aren’t easy to come by, the Whalen’s experienced a wave of success in 2015. After opening the season with a win at the TS Performance Outlaw Pull, they racked up seven wins in their local pulling circuit, and ultimately won the points championship. Seeing it all come together for a crew that’s been grinding it out for years was rewarding, but almost immediately the Whalen’s got busy readying the truck for the cut tire, 3.6-inch turbo, and revamped engine package it’s currently campaigning. By the time this issue of Diesel World hits the newsstand, they’ll already be in the midst of defending their title—a challenge we know they look forward to. DW The job of drastically cooling off hot, compressed air from the turbocharger lies in an extremely efficient water-to-air intercooler system. Thanks to a three-core intercooler from Precision Turbo & Engine, a centrifugal, belt-driven water pump, and 110-pounds worth of ice being consumed per hook, the engine’s intake temps never crest 60 degrees. Backing up the 1,800hp Cummins is a 4-disc Crower clutch and a Reverser transmission from Profab Machine. The Reverser is extremely common in the sled pulling world, mainly due to the weight savings, reliability, and simplicity it provides. Thanks to a Profab Machine Quick Change transfer case (i.e. drop box), gearing changes can be made on-the-spot (even while waiting in line to pull). The ability to change the truck’s final drive ratio in a matter of minutes via the Quick Change unit is invaluable as track conditions change or the driver (or crew) changes his or her mind on which gear to run.

Up front, the factory Dana 60 is still used, albeit with a Yukon Grizzly locker, 35-spline chromoly axleshafts, 6.17 gearing, a Proformance Pros billet yoke, and 1480 series U-joints. Cut tires are new to the Whalen’s (and the rest of the Pro Stock class for that matter), as D.O.T. tires were the only tread permitted prior to 2016, but so far they really shine on hard-packed tracks with bite. Two 18-inch wide Pioneer Giant Pullers are used up front, while massive 22-inch wide Pit Bull Super Pullers get the job done out back. Lightweight, 15-inch Real Racing Wheels get the nod at each corner. Prior to the 2013 season, the factory short bed was scrapped and the frame (and more importantly the wheelbase) was lengthened. At the same time, the truck made a visit to Crow Body Shop in Waverly, Illinois where it was treated to a one-of-a-kind, deep blue paintjob. In truck pulling, the name of the game is getting as much weight forward of the front axle as possible. Needless to say, it’s typical for most stock-frame pulling trucks to look like this: with the floor of the factory bed missing. A bare bones, all-business interior gets a taste of sophistication courtesy of an EZ2 Corsa data acquisition system, complete with a digital readout monitor that records every pull the truck makes. On a typical pass, Daniel walks the truck out of the hole, waits for a little drawbar weight, and then goes full throttle somewhere around (or after) the 100-foot mark. He told us that he tries to carry 4,500 rpm down the track. Total 4 Shares Share 0 Tweet 0 Pin it 4 Share 0
