2008 Ford Shelby GT500

We are proud to offer this 2008 Ford Mustang Shelby GT500 KR King of the Road. Powered by 5.4L supercharged V8 engine producing 540 horsepower and 510 LB-FT of torque and paired to a 6-speed manual transmission. Of total production in 2008 (1,011 units) around 328 were finished in black. The new KR, like the original, is essentially a GT500 that's spent another hour or two swimming in the testosterone pool. The supercharged V-8 benefits from a new cold-air intake and a Ford Racing low-restriction exhaust. We also tweaked the spark maps a bit, says Jamal Hameedi, SVT chief nameplate engineer. Life is great with forced induction, because small spark changes bring big power increases. With no change in boost pressure, output is bumped to a target of 540 horsepower and 510 pound-feet of torque, up from 500 horses and 480 pound-feet for the GT500. A six-speed manual will remain the standard and only transmission, the ceramic-metallic twin-disc clutch already rated to handle additional power (once in the hands of owners, few GT500s, Hameedi notes, remain at 500 horsepower for long). Still, the KR will get a new, lower 3.73 rear axle (versus the GT500's 3.31), which with the additional ponies should improve acceleration significantly (expect the KR to rocket from 0 to 60 mph in about four seconds flat or less-Z06 territory). Exterior changes are more significant, the most obvious being the two hood pins and that large, functional hood scoop. The KR benefits from a fully carbon fiber hood over the standard aluminum in the standard GT500's. For more information please call us at (319)-366-7600 or email sales@duffys.com.
