The 2011 edition of the Ford Super Duty pickup features an all-new diesel V8 engine. This torque-y beast was designed in-house and given a name that would send shivers down James Bond’s spine: Scorpion. The engine carries over the V8 configuration of the previous 6.4L Power Stroke, and it picks up a variety of technologies that have appeared on other recent gas and diesel engines, including a turbocharger.
The biggest change by far is the adoption of an inside-out engine layout, seen in other vehicles like BMW’s new turbocharged gas V8 and GM’s Duramax 4500. Since the V-engine configuration was first introduced, most models have had the intake system mounted in the valley between the banks and the exhaust incorporated on the outside. This new layout switches that around.
The Scorpion also features a new turbocharger manufactured by Honeywell, combining the principle of the sequential turbo approach with the variable vane system. This turbocharger uses the engine’s exhaust gases to spin up a turbine that drives a compressor to force more air into the engine, thus producing more power. The beauty of the system lies in its efficiency. It consumes very little energy under light load conditions, allowing for improved MPGs. When extra power is needed, the turbo helps expand the engine’s operating range to produce the required amount of boost on-demand.
Beyond the new turbo technology and layout, the remainder of the engine is business as usual. In order to meet the latest emissions standards, the Scorpion features many of the same technologies found on the latest light-duty diesels, which run cleaner, produce less soot and nitrogen oxide, use less fuel and still create gut-wrenching performance gains.
Among the most popular truck accessories and diesel performance parts for the Scorpion are genuine Ford parts than include diesel stacks, brakes, performance chips and a performance exhaust system. With all that brute strength under the hood, the possibilities for towing and other high-output activities are practically endless. But, since there’s no such thing as “”too much power,”” the addition of performance chips and a performance exhaust system can streamline your engine to maximize the output often lost in a series of restrictive factory settings. Used together, performance chips and a performance exhaust can maximize exhaust flow while creating an overall efficiency that translates to greater fuel economy by making adjustments to your air/fuel ratio, ignition timing and other key variables. To meet the demands of that extra power, many are also considering beefing up their brakes with the addition of reliable components like performance brake pads, proven to surpass their underperforming counterparts in durability by 20 – 40 percent. Additionally, performance brakes come slotted and cross-drilled to channel water away from the braking surface while providing the tough appearance worthy of the name Scorpion.
