Shelby GT

Fans of the Shelby GT can rejoice. The historic manufacturer is bringing the popular Mustang variant back for buyers of '13-'14 Mustang GTs. Debuted at the Los Angeles Auto Show, the Shelby GT is available in naturally aspirated and supercharged versions ranging from 430 to 624 horsepower.

"The Shelby GT was one of the most important vehicles in modern- day Shelby history," said John Luft, president of Shelby American ( "It kicked off Shelby's rebirth in Las Vegas by putting a Mustang-based small-block car into Ford dealerships. Ever since the Shelby GT went out of production, people have clamored for its return."

"Based on the standard Mustang GT, the total cost of our entry-level 2014 Shelby GT is only about $45,000, yet offers so much more than the previous model," said, Gary Patterson, Shelby American VP of Sales. "The performance-to-price ratio makes the Shelby GT perfect for any serious pony car enthusiast."

Buyers of the new Shelby GT will get a vehicle with a completely revamped visage courtesy of a Shelby GT front fascia, Shelby GT fiberglass hood, Shelby GT carbon laminated hood louvers, and unique 20x9-inch wheels wearing BFGoodrich tires. Backing up those revised looks performance mods, including a Borla exhaust, a Barton shifter, and a Panhard bar.

"While the Shelby GT is affordable for such an exclusive vehicle, a post title program allows us to take performance to new levels," said Shelby American VP of Production, Gary Davis. "Working with partners like Ford Racing, it is docile enough to be a daily driver and still dominate the track on the weekends."

Two of those new levels are 524- and 624-horsepower options. Both based on black or polished versions of the Ford Racing 2.3-liter supercharger. Along with the supercharger, these optional packages feature larger Wilwood brakes, Michelin Pilot Supersport tires, and GT/SC stripes. The higher output version is said to accelerate from 0-60 mph in about 3.7 seconds and eclipse the quarter-mile in the mid-11-second range. Of course, you can add even more peformance by adding additional hardware from the Shelby American parts line.

"No other carmaker offers this level of performance, heritage and iconic styling at this price, making the Shelby GT the best all-around American car in its class," John said. "Each car will be issued a Shelby American CSM number for documentation in our Shelby American Worldwide Registry to help maximize potential future value."

That value adds up to $14,995, on top of the vehicle price, while the Shelby GT/SC package starts at $27,995.


Regular readers will recall that we covered the installation and testing of ProCharger's variable-boost i-1 supercharger back in our June '13 issue ("Control Variable," p. 72). As a refresher, this supercharger offers three preset performance levels via an electronically controlled, constant- variable transmission in the supercharger. The system, also allows for a customized boost curve dialed in for your particular vehicle.

Well, ProCharger ( now offers the systems as tuner kits for those wanting to customize their supercharger system to suit their modified engines. To test these systems, the company recently took out the car we used in our story for testing. That car now wears headers and a full exhaust. In this configuration, running 7.5 pounds of boost and pump gas, the car ran a 10.87 at 131 mph. That was accomplished with the car at 3,850 pounds.

Currently, these i-1 kits are available for Coyote-powered Mustangs. On top of the performance news, ProCharger also announced at the '13 SEMA show that these systems are now available with an optional black finish.

Kenny Concept

While the world was focused on the debut of the '15 Mustang, Kenny Brown ( was busy hatching plans for what he would do with the next Mustang. What he has in mind is, you guessed it, more performance. However, that increased performance would come in streetable and race-worthy levels. To bring those ideas to life, Kenny turned to Jim Gerdom ( for these GT3 and GT3R concept illustrations.

From working on the early Saleen championships to building his own line of performance vehicles, Kenny is known for improving Mustang performance, particularly its handling, courtesy of his Advanced Geometry Suspensions. His company currently markets GT4 conversions for '11-'14 Mustangs, including the sport-touring GT4, the supercharged GT4-S, the Club Sport GT4-CS, and the race-oriented GT4-RS. He is obviously ready to continue tweaking the forthcoming Mustang.

"Should there be interest, the Kenny Brown GT3 Mustang Concept will be a formidable, no-compromise driver's car for road, track days, or racing and a fantastic showcase for our products and capabilities." Kenny said, "With the intent of the new Mustang to be a world car and the continuing growth of GT3 versions of the world's best sports cars, a GT3 Mustang Concept seems contemporary and a natural progression."

If you'd like to see these concepts become reality, be sure to let Kenny know.
