2007 Ford F-250 - Happy Hunting

A 700hp Sleeper 6.0L

One undeniable truth about diesel performance is that dynos can lie—but the dragstrip never does. Knowing this, we just had to take a closer look at Tommy Barnes’ 12-second ’07 F-250. After the 8,400-pound crew cab Super Duty trapped 107 mph in the quarter-mile yet only made 577 rwhp on a chassis dyno, we crunched the numbers. As it turns out, Tommy’s trap speed and elapsed time at the track mean his 6.0L Power Stroke is getting roughly 700 ponies to the pavement.
After owning his fair share of Mustangs and even a Harley-Davidson F-150 SuperCrew with a Saleen V-8, Tommy began to take note of all the high-powered diesels in his area. “I was seeing how much more power they were making than the gas trucks—and I was getting embarrassed,” he told us. “I just felt like I was throwing money away with the gas motors.” Needless to say, when a friend offered him a smoking good deal on the Lariat-optioned F-250 you see here, he jumped on it.

In bone-stock form and with more than 100,000 miles on the odometer, the 6.0L was due for an EGR delete, head gaskets, and studs, so Tommy turned to nearby Stroked Diesel Performance for a helping hand. After hashing out a plan to add both power and reliability to the truck’s repertoire, Stroked Diesel Performance owner Nick Copenhaver got to work. The heads were sent to River City Diesel for some port work and upgraded valvesprings, while a fresh bottom end that retained the factory rods but replaced the stock pistons with a set of fly-cut, 16.0:1 compression Mahle units was put together. Other valvetrain upgrades included a Stage 2 Colt cam from River City, and chromoly pushrods.
When it was time to amplify the 6.0L’s injection system, Warren Diesel got the call. To keep a set of its thirsty 285cc injectors happy, Warren supplied a dual high-pressure oil pump kit that added a second, beltdriven pump to the equation. Thanks to the dual pump system and according to data-logging info, 4,500 psi of injection control pressure (ICP) can be maintained at full throttle. This translates into horsepower-friendly 30,000-psi injection pressures. An AirDog II system with a revised gerotor lift pump feeds diesel to the engine, and a Driven Diesel regulated-return kit ensures each injector receives its fair share of fuel.

Breathing through a Jobe Performance intake is a 68mm Powermax turbo from River City Diesel. Intake temps and EGT are drastically reduced thanks to a Banks Techni-Cooler intercooler system, and a TiAL blow-off valve keeps boost pressure spikes from damaging the turbo. The truck’s exhaust path was opened up courtesy of a 4-inch turbo-back system from MBRP.
Fortifying the 5R110 TorqShift automatic was left to the experts at Sun Coast. Upgraded clutches, steels, pressure plates, and a billet input shaft made the cut, as well as the company’s triple-disc 6.0L torque converter. Stroked Diesel Performance tuned both the TCM and PCM via SCT software, which makes all engine and transmission modifications work together seamlessly.
With the stock ride height, 20-inch Harley-Davidson wheels, and three-ball hitch, the truck doesn’t draw a whole lot of attention, but maybe that’s the point… Whether it was by design or personal taste, Tommy’s F-250 resembles thousands of well-kept, late-model Super Dutys—most of which are usually laced with nothing more than an air intake, exhaust, and programmer. We love the fact that this 12-second sleeper bucks that trend. After all, coming across a hot-running 6.0L Power Stroke is every Chevy or Ram owners’ worst nightmare.
