The original Mustang Cobra Jet was unveiled back in 1968 when it was powered by a 7.0-liter V8 engine with massive four-barrel carburetors and an output of 335 HP. Since then, things have evolved immensely, leaving the 2013 Cobra Jet with a 5.4 liter DOHC supercharged engine that delivers an impressive 430 HP, but that can still be much improved by today’s standards. Enter Ford Racing.
Ford Racing has prepared something amazing for the 2012 SEMA Auto Show: a Cobra Jet Twin-Turbo Concept that features a pair of twin turbochargers attached to the 5.0-liter V8 engine, eliminating the supercharger which provides instant on-demand power, but loses it at high boost levels. This turbocharger system uses the same technology as Ford’s EcoBoost engines and, according to Ford Racing, has the benefit of providing much less power loss. The lag experienced by turbochargers is minimized with the use of smaller turbochargers that are just as effective, but allow for the airflow necessary to power the muscle car. The turbochargers feature turbine wheels that are made from titanium aluminide which 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. This system also provides better responsiveness, very low inertia, and very low internal friction.
The Ford Mustang Cobra Jet Twin-Turbo Concept was prepared solely to highlight Ford’s advances in turbocharging technology, but the exterior also plays a part by showing off the new global Ford Racing livery. The exterior is painted in a crisp white finish and combined with asymmetric black and blue stripes running over the top of the car from bumper to bumper. The side of the car shows these stripes as they sweep upward before ending with the traditional striking cobra head in black with blue accents.
"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.
“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,” added Deneweth. “So we decided to apply that knowledge to the Mustang Cobra Jet to showcase what our engineers and suppliers know how to do.”
