Ford unveils a twin turbocharged 5.0L Mustang Cobra Jet at SEMA
You read that right – the 2013 Ford Mustang Cobra Jet shown on the right packs the familiar 5.0L V8 that is found in the Mustang GT, the Mustang Boss 302 and the Mustang Cobra Jet but unlike those naturally aspirated powerplants…this new 5.0L packs a pair of Borg Warner turbochargers that help this to be one of the fastest Cobra Jet Mustangs ever. While the majority of the specifications of the Twin Turbo Cobra Jet Mustang are still unknown, Ford Racing representatives told us that in initial testing, this new twin turbo Mustang has turned out quarter mile times in the high 8 second range. Numbers like that would allow the Ford Racing Mustang Cobra Jet with the new turbo setup to be among the absolute quickest factory drag packages among the Detroit Big 3.
“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.”
Some of you out there who are somewhat familiar with turbocharging technology might be asking why this Twin Turbo Cobra Jet Mustang would be better than the older supercharged or naturally aspirated Cobra Jet drag packages considering that turbochargers have an inherent level of “lag” while the turbochargers spool up to the required internal RPM to provide boost. To fix this problem, Ford Racing has worked with Borg Warner to build turbochargers for the Twin Turbo Mustang Cobra Jet that were initially intended for use on the EcoBoost engine of the production level Ford Focus ST and these tiny turbos provide gobs of boost with almost no noticeable spool time thanks to their compact, lightweight construction.
“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.”
While a supercharger might help the Mustang Cobra Jet deliver the power more quickly as engine RPM rises, the supercharger also carries a great deal of parasitic losses that eat up the power helping to move the car down the track. For example, the supercharger used on the blown 2013 Mustang Cobra Jet uses almost 100 horsepower just to spin the supercharger internals whereas the turbochargers don’t steal any power from the engine – instead deriving the force to spin them from the natural flow of the exhaust system.
