The Chevrolet Corvette Z06 is the pinnacle of the iconic sports car now that it employs a flat-plane crankshaft V8 positioned at the center of the chassis. This is a highly sought-after product but due to supply constraints, it has been a challenging piece of machinery for enthusiasts to get their hands on.

While we wait for Chevrolet to straighten things out on the modern car, we continue to be amazed at what private owners are achieving in older Z06 models. One such example is this 2011 model owned by Pierce Marshall who took it to the Texas Mile and achieved a staggering top speed result.

Annoyingly, we don't have any technical specifications relating to this particular build, but Marshall confirms that the Carbon Edition model is powered by an LME 6.5-liter V8 from a C5R racecar supported by a pair of turbochargers, giving it an estimated output of 1,200 horsepower. The build was conducted by Andy Mages who runs AMD Performance; specialists in LSA and LS4 powertrains.

Despite winds being somewhat heavy, the tuned Corvette was able to hit a staggering top speed of 242.7 mph after one mile with a quarter-mile speed of 140.3 mph. In half a mile, it was able to clock 184.4 mph. That's a fair chunk more than the 196-mph top speed of the stock C8 model.

The C6 Z06 Carbon Edition is one of the most sought-after Corvettes in existence. It sports a unique carbon body kit with some performance-minded technical revisions with power coming from a large 7.0-liter V8 rated at 505 hp. In standard guise, it is unlikely to have the aerodynamic ability to keep things stable at more than 240 mph.

That's why Marshall fitted his limited chopped-up 'Vette with a prominent rear wing. With this result, the Texas Mile event runners confirm that this modified sports car was the record holder for the weekend, besting the likes of a Mustang Shelby GT500 with a top speed of 232.6 mph, and a brave biker reaching 223.1 mph with his 2008 Suzuki Hayabusa.
