540 horse power, right off the showroom floor.
With the ’08 model’s supercharged 5.4-liter V-8 underhood wearing a Ford Racing Power Upgrade Pack (revised ignition timing and throttle calibration, plus a cold-air intake),
the 2008 KR outdoes its predecessor by 205 horsepower—a margin greater than the entire output of some V-8 Mustangs of the 1980s—with 540.
That herd travels rearward through a six-speed manual with a short-throw shifter to a shorter 3.73:1 rear end (stock is 3.31:1) for quicker giddyap,
while snorts and whinnies get an extra edge from a revised exhaust system.
