There's a new racier pony car making its debut at Sin City's SEMA Show and it's called the Mustang Cobra Jet Concept.
It's a prototype version of Ford's factory-built turnkey drag racer that replaces the 2013 Mustang Cobra Jet's 5.0-liter V8 unit that's available with or without a supercharger with a new iteration of the V8 featuring a pair of turbochargers incorporating the brand's EcoBoost technologies.
According to Ford's motorsports division, while superchargers provide instant on-demand power, they also require a lot of power especially at high boost levels. As an example, Ford says that the 2.9-liter blower fitted on the 2013 Cobra Jet uses as much as 100hp to drive the supercharger.
“When done right, turbocharging is just as good as or better than supercharging,” said Ford turbocharger design and release engineer Dave Born.
“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 added. “We’ve also got some other enhancements to help improve the responsiveness; we have very low inertia and very low internal friction.”
Ford did not reveal the horsepower numbers, nor if and when the twin-turbocharged Mustang racer will head for production.
In addition to the newly developed prototype engine, the SEMA Show Cobra Jet project car also adopts Ford's new black-and-blue racing stripe livery.

Most serious performance car manufacturers outside the US figured this out in the 80s, Ford is just 40 years late, typical Ford, stuck in the past. I suppose that's why they have to plaster twin turbo everywhere on the car because nobody can believe it.
And those turbos must be tiny because I can't see them anywhere. Note to Ford, everyone else has overcome this problem, and a simple mechanical fix is one large turbo and one small turbo. I assume you've tried this and can't make it work, perhaps you should consider hiring qualified engineers, I know that cuts into your marketing budget, and those big year-end bonuses for your fat CEOs, and a company with only 160,000 employees, but maybe you should think about making the investment.
This car going into production anytime soon, since US auto manufacturers spent so much time and money convincing their customer base that turbos were worthless. The last ford turbo, the SVO sat on deal or lots for two years after their production, and it could only be finally move when they were sold at a hefty discount. Maybe in another 30 years A turbocharged Ford on the street. Also turbocharging is what you do to reduce the weight on cars that were meant for road racing, small turbos in particular have little appeal for drag racers.
3 things- 1. The turbos are likely tucked under exhaust manifolds you can't see them since mod motors are so damned wide.
2. The turbos are not that small, I believe I read somewhere the wheel was 70+ mm diameter.
3.The hot side piping of a sequential turbo set up on a V engine would be a PITA. Plus ball bearing turbos have eliminated the need in some cases for sequential turbos.
Yes, Aaron, that's why you're the expert authority of automotive engineering. Please enlighten us with your horseshit wisdom. Please. I'm not going to list all the factual errors in your post, but I'll include some actual facts. You know, the ones that can be verified, oh by, reading perhaps. For example, when the Porsche 911 Turbo made its debut, it had serious turbo lag. So much so that many considered the car undriveable. Fast forward to 2012, the Mitsubishi Evo still has so much lag it's annoying to those using it as a daily driver. BMW eschewed their twin turbo for a twin scroll design? Why? To reduce lag. One caveat, it didn't make as much power as the twin turbo (when maxed out), but it was more responsive as a daily driver. So, before you spew your bullshit crap and bad mouth a company that recently has won multiple awards for their engines designs, think before you write. It pisses those of us off when disinformation is presented.
