The KR’s 5.4-liter V-8 Gets the Royal Treatment
Just like its namesake, the 2008 ‘King of the Road’ packs a walloping dose of Ford performance power under its massive composite hood scoops. The Ford SVT-engineered 5.4-liter supercharged V-8 is treated to a Ford Racing Power Upgrade Pack that boosts horsepower to an estimated 540 and torque to 510 ft.-lbs., thanks to revised ignition and throttle calibration and a cold air intake system that replaces the stock unit.
Calibration modifications include advancing the ignition timing as well as re-mapping of the electronic throttle settings to provide quicker throttle response for better off-line and mid-range acceleration. Increased throttle response will be met with a sharper roar from the Ford Racing-inspired exhaust system.
Power is delivered to the rear wheels through a Tremec TR6060 six-speed manual transmission and 3.73:1 rear axle ratio, upgraded from the standard GT500’s 3.31:1. Gear selection is courtesy of an all-new Ford Racing short-throw shifter making its debut on the KR. Topped with a white ball, the new shifter is 25 percent shorter than the unit on the GT500 providing for crisper, sharper shifts.
Ford SVT, Ford Racing and Team Shelby worked together to develop the KR’s suspension tuning. Based on initial work by Ford Racing and the team at Shelby, often at Shelby’s own facility on the grounds of Las Vegas Motor Speedway, Ford SVT chassis engineers will apply fine tuning techniques to prepare it for the streets.
“The production Shelby GT500 was maximized to deliver the perfect balance between ride and handling,” said Jamal Hameedi, chief nameplate engineer, Ford SVT. “In that same ride versus handling continuum, the KR will lean heavier towards all-out handling while still making it drivable on the street.”
Chassis engineers worked closely with the engine department in a holistic approach to the development of the KR, tuning the suspension to best optimize the engine enhancements.
“We aren’t fixing our attention on one or two attributes, but working on the vehicle as a whole,” stated Gary Patterson, vice president of operations for Shelby Automobiles. “The throttle response, power delivery, exhaust note, and handling should all gel together to deliver a total driving experience.”
The GT500KR will feature unique spring rates, dampers, stabilizer bars, and strut tower brace, all designed specifically for the KR, to deliver the precision handling package.
Shelby Mustangs have already achieved some impressive highlights showcasing an enthusiast demand that is unmatched in the business:
• The first 2007 Shelby GT500 available to the public sold for $600,000 dollars at the 2006 Barrett-Jackson Collector Car Auction in Scottsdale, AZ benefiting the Carroll Shelby Children’s Foundation.
• 2007 Shelby GT VIN#1 also went for $600,000 at charity auction, this time at the 2007 Barrett-Jackson Collector Car Auction (and the winning bidder also took the opportunity to purchase VIN#2 at MSRP).
• Shelby GT-H coupes auctioned off to Ford dealers after completion of Hertz rental duty consistently average $50,000, with high auction bids of $90,000.
