Mustang Madness! 2011 Mustang GT 5.0 and BOSS 302R

You may have heard rumblings about Ford’s engineers in Dearborn tinkering away at something special, but now we can say without a doubt: the 5.0 is back. In 2011, the Mustang GT will be powered by an all new 5.0 liter V8 that will deliver 412 horsepower and 390 ft-lbs of torque. The naturally aspirated feat owes much of its efficiency to the 4-valve Twin independent Variable Camshaft Timing (Ti-VCT), producing a substantial amount of power while still upping the fuel economy to 25 miles per gallon.

This double-overhead-camshaft configuration employs two camshafts per cylinder bank – one camshaft to operate the intake valves and one camshaft to operate the exhaust valves. Ti-VCT rotates the camshafts to advance or retard the cam timing, based on several measures including throttle opening. An element unique to the Mustang GT 5.0-liter V8 is that Ti-VCT is actuated by camshaft torque, with assistance from pressurized oil. Using camshaft torque energy should provide faster throttle response and maximize use of existing energy, aiding fuel economy.

An additional element is the increased capacity and baffling of the deep-sump stamped steel oil pan to enable sustained high-rpm use and keep the oil change interval at 10,000-miles. Piston-cooling jets also were incorporated for performance-minded customers and for faster oil warm-up on cold start.

Specially designed tubular exhaust headers were developed to maximize exhaust pulse separation and improve flow. This was a response to customers immediately swapping the headers out for 3rd party replacements for an easy performance boost, so the engineering team sought to make them the best from the get-go.

To manage all the new grunt and help along the miles per gallon, the Mustang GT will gain a new 6 speed transmission. With the automatic, the estimated miles per gallon is 25 highway and 17 in the city. The manual will match the current estimated 24 mpg highway and 16 mpg city numbers, but getting an extra 112 horses with no compromise is very much getting your cake and eating it too.

Driving dynamics have been sharpened up as well, as Stabilizer bar diameters, spring rates and dampers all have been tuned for improved dynamics, and a Brembo brake package will be finally available, something that Mustang enthusiasts have been itching for. The package will include the 14-inch vented front discs from the GT500, 19-inch alloy wheels and summer performance tires. Hopefully I can get Ford to slap a pair on this guy.

The look of the Mustang GT won’t change dramatically from the recent refresh, but 2011 GT’s will proudly sport 5.0 fender badges, as well as a host of new colors such as Yellow Blaze Tri-Coat, Race Red and Ingot Silver.

Inside, the driver will notice the speedometer increased to 160 mph, and the tach redline is upped from 6,500 to 7,000 rpm.

Those who may feel left out of the V8 party shouldn’t fret, as with these developments, the 2011 Mustang V6 will have its horsepower increased to 300, matching the current V8.   and if that weren’t enough, there’s more:

Hot on the tail of the news of the 2011 5.0 Mustang GT is the announcement that Ford Racing is returning the road racing legend back to the track.

Dubbed the BOSS 302R, this factory-built race car is set to go fro Grand-Am, SCCA, and NASA classes.  “From Shelbys to Bullitt, Mach and Cobra Jet, it is now time for BOSS to join the list of America’s most coveted Mustangs’ says Jamie Allison, director of For North America Motorsports.  The BOSS 302R will come equipped with the new 5.0 –liter 4-valve engine like the 2011 GT, a 6-speed manual transmission, roll cage, race seats, harness, data acquisition, and race dampers/springs, plus a Brembo brake and tire package. I had a brief chance to hop inside one, and I’m so very much looking forward to sitting in one on the move.

A Grand-Am Homologation Package (M-FR500-BOSS R1) will also be ready to compete in the Continental Tire Sports Car Challenge at Daytona on January 29th, 2010, where five BOSS 302R’s will be delivered for the opening race.  These will feature a sealed high-output race engine with an upgraded cooling system, a close-ratio six-speed transmission with integral shifter, a seam-welded body, race suspension/KONI dampers and ABS brake tuning, race performance exhaust and a high-speed balance one-piece driveshaft.

The BOSS 302R will be replacing the highly successful Mustang FR500C (this one)that has won three Triple Crown championships in five years in KONI competition, and has also seen success in FIA GT4, winning the driver’s championships in ‘07 and ‘08.

“Racing has long served as a technical proving ground for production engines,” continues Allison, who echoes the belief of many that great road cars stem from excellent race cars.  The great part is, you don’t have to be left out of the action: the BOSS 302R is available through any Ford dealer. While obviously not street legal, anyone can walk in, go straight to the Ford Racing performance parts counter, and place an order for their track day or SCCA races. The base package starts around $79,000, while the Grand-Am packages will start at about $129,000. It’s best to get a move on, however, as only 50 will be built this year, so if you have the means and the proper forum for make this car shine, now is the time to get a hold of one.

    Well, how do you excite a reasonable healthy, successful 75 year old business man considering

    all the bad stuff that is going on in the world today – in my case, I have ordered the new

    5.0 Mustang GT. I have owned 5 Mustang GT’s and this one, even without drivng it yet, has

    me squirming in my BVD’s – itching to get on the open road – anticipating the thrill of

    blowing a Camaro off the road – and doing it with 25 mpg! Don’t you love being an American,,

    in the land of the free and home of the brave! I think I inhereited some of the racing

    genes that my hero Paul Newman possessed – not his looks, not his money, not his talent,

    just the ones that stimulate the brain to mash the pedal just a little bit harder!
