Last year at SEMA, Chevrolet absolutely stole the show with its COPO Camaro Concept. Not to be upstaged by their Bowtie counterparts, the boys over at the Blue Oval have countered with the car you see here, the Mustang Cobra Jet Concept. Built by Ford Racing and based on the 2013 Mustang Cobra Jet, this one-off racer features a pair of twin turbochargers attached to a 5.0-liter V8 using the same technology as Ford's EcoBoost engines.

While the current crop of Cobra Jets are plenty fast, running eight-second quarter miles in NHRA trim, Ford Racing says that the 2.9-liter Whipple supercharger currently used requires as much as 100 horsepower to operate – horsepower that isn't being delivered to the meaty rear tires. The turbos, however, provide a much lower parasitic loss in power. Relatively small turbos – similar to the ones used on the Focus ST – were also used on the concept, ensuring that there would be as little lag as possible.

Will we see a production version of the twin-turbo Mustang Cobra Jet Concept in the future? Perhaps, especially as the next generation Mustang has long been rumored to get an EcoBoost engine. Until then, check out the plethora of photos (both live and stock) of the car as well as a video of the Cobra Jet in action below.

LAS VEGAS, Oct. 30, 2012 – The Ford Racing Mustang Cobra Jet concept revealed today at the Specialty Equipment Market Association (SEMA) show proves there is indeed a replacement for displacement.

In the perpetual quest to stay ahead of the competition, for the first time ever Ford Racing has equipped its factory-built turnkey drag racer with a turbocharged engine, adopting the same award-winning technology found on road-going EcoBoost® engines.

Winning heritage

When the original Mustang Cobra Jet drag racers rolled out of the Mustang factory in 1968, they relied on 7.0-liter V8 engines with massive four-barrel carburetors to propel them down the strip.

"When a new generation of Cobra Jets arrived four decades later, they immediately began winning with a modern, fuel-injected 5.4-liter V8 topped with a belt-driven supercharger," recalls Jesse Kershaw, Ford drag racing competition manager. "Over the past four years, the Cobra Jet has gone on to become both a fan and competitor favorite, the most successful late-model vehicle in drag racing."

"Racing predates Ford Motor Company. Henry Ford himself raced the 999 and won in 1901 to generate interest for the new company," said Jamie Allison, director of Ford Racing Technologies. "We haven't stopped since.

"We've competed in almost every category of auto racing, from deserts to road courses to ovals and drag strips over the past 111 years, often with cars and trucks based on our production models, including the Mustang," Allison added.

In 2011, the Mustang GT's all-new 5.0-liter V8 found a home in the Cobra Jet, both with and without a supercharger.

"Despite its smaller displacement, the improved breathing of the 5.0-liter with its twin independent variable camshaft timing and Boss 302 cylinder heads provided comparable performance while showcasing the high technology available in street Mustangs today," said Rob Deneweth, Cobra Jet powertrain development engineer.

"Ever since relaunching the Cobra Jet in 2008, we've continuously evolved the engine to be more optimized for drag racing and to produce more power for its NHRA class," he added.
While superchargers provide instant on-demand power, they can also sap a lot of power, especially at high boost levels. The 2.9-liter blower employed on the 2013 Cobra Jet uses as much as 100 horsepower to drive the supercharger. That's power no longer available for acceleration.

Two turbochargers, no waiting

Fortunately, every internal combustion engine has a plentiful source of energy that normally goes to waste right out the exhaust pipe. Turbochargers harness the thermal and kinetic energy in the exhaust gases to drive turbines and compressors that force more air into the engine for a big increase in power without most of the parasitic losses of a supercharger.
"Ford has embraced turbocharging technology and a lot of our production engineers are working with the technology on a daily basis, so we have a lot of knowledge," said Deneweth. "We decided to apply that knowledge to the Mustang Cobra Jet to showcase what our engineers and suppliers know how to do."

Turbocharger design and release engineer Dave Born joined the Cobra Jet team after working on the 3.5-liter EcoBoost V6 for the F-150 to help make this concept a reality. "When done right, turbocharging is just as good as or better than supercharging," Born confirms.
"To overcome the biggest perceived drawback of turbocharging – the lag – we've selected the smallest possible turbos that will give us the airflow we need," he adds. "We've also got some other enhancements to help improve the responsiveness; we have very low inertia and very low internal friction."

NHRA competition rules for the stock classes Cobra Jet races in require parts like turbochargers to be derived from production components. Borg-Warner™ has supplied smaller, more efficient turbochargers based on the units used in the Focus ST for the Cobra Jet concept. Smaller than those found in most other drag racing applications, the turbine wheels are made from titanium aluminide that reduces the rotational inertia by 50 percent. Along with a shaft riding on low-friction ball bearings, the compressors can spin up to 150,000 rpm almost instantly.

The same integrated, electronically controlled wastegates used on production EcoBoost engines enable the turbos to keep spinning and generating the boost pressure needed for low elapsed times and high trap speeds at the strip.

One of the top reasons for a car company to go racing is the rapid learning curve it provides and the lessons that can be fed back into the vehicles customers drive every day.
"We're already using ball bearings in the turbocharger of the 6.7-liter Power Stroke® diesel V8 in Super Duty trucks," says Born. "We're also evaluating materials like titanium aluminide for the turbine, and it could find its way into future production programs as the costs come down."

New global Ford Racing livery

The Cobra Jet project car features its own unique take on the new global Ford Racing livery that is also highlighted at SEMA. The white body is accented with an asymmetric black and blue stripe running over the top of the car from bumper to bumper. The Cobra Jet's flanks blend an upward sweeping version of the stripe with the traditional striking cobra head executed in black with blue accents.

Following the SEMA show, Ford Racing engineers including Deneweth and Born will continue to develop both the performance and durability of the twin-turbo Cobra Jet.

"For every Cobra Jet model we release, every powertrain goes through hundreds of hours of dyno testing and a minimum of 50 runs on the drag strip before we'll sign off on the durability and capability of that engine and car," says Kershaw. "Like Ford vehicles for the street, we want to provide our racing customers with cars that are best-in-class, affordable and reliable."

      A pair of twin turbochargers? Ford is rocking a quad-turbo setup here, huh?

      I'll bet we'll see a variant of this in the 2015 GT500.

      There will be a twin turbocharged 5.0 but it will be a truck engine. And quite possibly a top of the line 7.0 to give people who need the torque of the power stroke without all the diesel expenses and headaches. Imagine it for a second and ten speed transmission and about 850-900 torques!

      Actually those are EFR turbos, which are quite a bit larger than the 2.0l Focus engine's turbo- 71mm vs 50ish-mm compressor wheel exducer.

        The Borg Warner EFR is a whole line up of different sizes not just one but I have no doubt they went with a bigger turbo.

      "Using the same technology as Ford' EcoBoost engines". So forced induction and direct injection? Pretty sure that "technology" has been around for several decades

      Ford V8 + Twin Turbo sound is just lovely.

      Is that the next motor for the GT500? Ford needs to work the car some more so it can beat the LT1 on the track. IRS and this motor might just do it.

        It beats the LT1 on plenty of tracks the LT1 is just trying to keep up usually like at Willow Springs, Gingerman and Mazda Raceway to name a few. I don't have time to list every drag strip in existance....

      There is not going to be an EcoBoost V8. Ford debunked those rumors shortly after the 5.0 came out. The EcoBoost engine most likely to appear in the next gen car is a 4-cylinder. The EcoBoost V6 is too close to the Coyote in terms of power output, so it is not likely to appear in the Mustang except as a special edition.

        Umm i thinks thats why people are thinking the next GT500 possibly

      So much awesomeness... Just wish they'd found more modern wheels. Make a street legal version of this setup, and I'd buy it.

      I love the tires. They're mildly menacing but not overly loud. Almost as if they silently say "not gonna happen" to folks thinking of racing it.
