In stock form, the 412 hp Ford Mustang 5.0 GT is indeed a quick car, but now thanks to the efforts of NASCAR driver Dave Ragan and Ford Racing Performance Parts, it has now set the world record for production cars.
During an instrumented test at Bristol Motor Speedway in Bristol, Tennessee, as part of the World's Fastest Half Mile Speed Trials; Ragan was able to coax his Mustang GT (modified only with a Ford Racing/Whipple Supercharger and FR3 performance handling pack) around 1 lap of the track in just 19.5 seconds. By contrast, a fully prepped NASCAR racer will do the same circuit in 15.5 seconds!
But the most interesting part about all this? Well, for about $45,000 the average guy or gal can basically replicate the car which Raglan drove – a 2011 Mustang GT starts around $30,000, give or take, while the supercharger package, which adds around 212 more hp, costs $7500.
The suspension upgrades, which include lowering springs, adjustable shocks, anti-roll bars, jounce stoppers and a strut tower brace, retails for $1800. So, even adding in labor charges, you're still going to be in the low 40k range by the time all's said and done.
