Photo 2/15 | 6 4l Power Stroke Diesel | We’re not used to seeing 6.4L Ford-powered trucks sporting big single turbochargers. However, given the horsepower and torque Clay Stewart’s ride puts down, we just might see more of them. With 895 hp and 1,436 lb-ft of torque, Clay’s ’08 F-250 can outrun just about everything on the road.
Photo 3/15 | No Limit Fabrication Intake Tube | The turbo setup starts with a No Limit Fabrication 5-inch intake designed for high-horsepower 6.4L engines. The chrome unit uses all the stock sensor locations and even includes a pre-filter for longer air filter life.
Photo 4/15 | 7mm Turbocharger | Speaking of turbos, Clay runs a rather large 75mm that features an 87mm turbine to promote exhaust flow, but also a rather tight 0.91 A/R housing that helps with spool-up. Exhaust exits via a 5-inch downpipe Clay built himself.
Photo 5/15 | Elete Diesel 5r110 Transmission | A stout transmission is needed to handle the nearly 900 hp Clay’s Power Stroke generates. Elite Diesel built a 5R110 automatic with billet input and intermediate shafts, hubs, and a revised clutch count in the transmission. With all these modifications plus a 13-inch torque converter from Diesel Performance Converters, the drivetrain holds up just fine.
Photo 6/15 | H And S Mini Max Tuner | One of the things that first fooled us about Clay’s deceptive rig is its lack of instrumentation other than a single H&S Mini Maxx. Clay says it gives him everything he needs, including EGT readings as high as 1,750 nerve-wracking degrees. Programming for the Mini Maxx is done by Gearhead Automotive Performance.
Photo 7/15 | Up Pipe Assembly | Parts from a variety of manufacturers are used to mount the S400-frame BorgWarner turbo. This wrapped up-pipe setup is from River City Diesel and includes a provision for a wastegate if Clay needs one. The up-pipe assembly is connected to a pedestal from Maryland Performance Diesel, which actually mounts the turbo on the engine.
Photo 8/15 | No Limit Fabrication Seven Layer Boot | To keep the compressor’s 58 psi of boost in check, No Limit Fabrication seven-layer boots replace the factory tubes throughout the air-intake tract.
Photo 9/15 | Air Dog Lift Pump | An AirDog 165-gph lift pump sends fuel to the engine at 12 to 15 psi.
Photo 10/15 | Elite Diesel Fuel Bowl Delete Kit | The remainder of the fuel system is comprised of such Elite Diesel Engineering pieces as a fuel bowl delete and this custom block that sends fuel back to the tank and to both high-pressure pumps.
Photo 11/15 | K16 Injection Pump | It’s hard to see, but a second stock K16 injection pump is tucked under some of the turbocharger piping. With two stock pumps and 100-percent-over injector nozzles, the F-250 has a 1,200hp-capable fuel system on tap that’s ready to go if Clay ever wants to step up his power game.
Photo 12/15 | 2008 Ford F 250 Super Duty | The rubber meets the road through 305/45R22 Nitto NT420S tires, which provide good street manners as well as on-road traction. A big contributor to the F-250’s blacked-out look is its American Force Rebel SS8 wheels, which are 22 inches in diameter. The rear of the truck is also a little lower than stock, thanks to the removal of the rear blocks.
Photo 13/15 | Precision Metal Fabrication Traction Bars | Perhaps the only external cue that the Ford has something other than basic performance in mind, are these traction bars from Precision Metal Fabrication.
