2008 Ford F-250 6.4L Power Stroke - Diesel Power Challenge 2014 Competitor
If there's not already enough pressure going into Diesel Power Challenge, try being the previous champion. No single competitor has more pressure placed on him than this one. But by talking to Wesley Beech you'd never know he was returning to defend the crown. Wesley's cool and calm demeanor sometimes makes it hard to get a good read on him, but it is this very trait that worries the competition the most.
Building on last year's winning setup, Wesley made strategic changes where necessary and left the truck alone in areas that worked well last year. Fueling remained nearly the same: a Beech Performance dual K16 high-pressure fuel pump kit and a pair of Industrial Injection Dragon Fire pumps. Race-ported fuel rails, Exergy Engineering 100-percent-over injectors, and a single FASS Titanium Series 220-gph lift pump round out the mix. The inside of the 6.4L is fortified with R&R rods, Beech Performance heavy-duty pistons, a Colt Stage 3 billet camshaft, Hamilton Cams' valvesprings and pushrods, ported heads, 2mm oversized valves, and ARP head studs.
Compressing the air needed to burn all the available fuel is a set of Beech Performance Work Stock compounds. A factory variable-geometry high-pressure charger was fitted with a 59mm BatMoWheel compressor wheel from Bullseye Power, and the factory atmospheric unit was stuffed with an 80mm wheel. While similar in size, this turbo arrangement is a departure from last year's winning combination, with hopes of better overall performance. A vane brake from BD Diesel provides exhaust braking capability, while the company's Positive Air Shutdown is employed in case of a runaway. Preventing damage from overboosting is a pair of 50mm Turbosmart Pro-Gate wastegates.
Feeding fresh air to the chargers is an intake from No Limit Fabrication. Beech Performance ported 6.0L exhaust manifolds with V-band clamps, and stainless up-pipes route exhaust to the turbos. Spent gases exit through a Flo-Pro 4-inch downpipe connected to a 5-inch exhaust, and ultimately vent out a Beech Performance 7-inch aluminum stack. No Limit Fabrication intercooler piping is used on both sides of the BD Diesel intercooler.
Delivering power to the ground is the job of a Sun Coast–built competition 5R110 TorqShift five-speed automatic transmission. Fitted with the company's triple-disc torque converter and billet flexplate, this slushbox should be able to handle anything the powerful 6.4L can hand it. Keeping the fluid cool is a deep pan from AFE, and an RCI transmission blanket wraps it in case of the unthinkable. Outback, a Dana 80 axle was swapped in place of the factory unit and fitted with 37-spline 4340 chromoly shafts, Beech Performance billet main bearing caps, a Detroit locker, a custom girdle by Toni Rizzi, and an AFE cover.
A 4.5-inch Rough Country lift kit with a Flight Fabrication four-link provides the altitude for this big Ford. Keeping axlewrap to a minimum is a set of custom Flight Fabrication traction bars, and (for sled pulling) Beech Performance suspension stops. Providing stopping power for the behemoth are Brembo brakes at all four corners.
By building on last year's winning combination, without completely changing what made the truck work, we expect to see Wesley do exceedingly well again in this year's competition—and carry the legacy of the 6.4L Power Stroke even further.
