A twin-turbocharged C8 Corvette has just set a new quarter-mile record for the mid-engined sports car.
This particular Corvette has been extensively modified by Extreme Turbo Systems and apparently pumps out over 1,000 hp to the wheels thanks to a pair of turbochargers, an upgraded fuel system, water-to-air intercooler, new intake manifold, and a piggyback ECU.
Extreme Turbo Systems says that this car was being tested when it unexpectedly ran a 9.05-second quarter-mile at 159 mph (255.8 km/h), beating the 9.36-second run set by YouTuber Emelia Hartford in her C8 Corvette just a couple of months ago.

What’s particularly impressive about this run down the quarter-mile, as well as all other twin-turbocharged C8s out there, is the fact that tuners have steal yet to crack into the ECU of the car, making it difficult to adjust important metrics like the air-fuel ratio and forcing aftermarket companies to install piggyback ECUs that operate alongside the factory ECU.
The reason why the C8 is so difficult to tune is due to the fact that it uses GM’s Global B architecture that features extremely strict cybersecurity measures that make it virtually hack-proof. And, according to Corvette executive chief engineer Tadge Juechter, the automaker has no plans on opening up the ECU for tuners.
“The aftermarket crew is very talented and resourceful,” Juechter said in an interview with Muscle Cars & Trucks a couple of months ago. “They have been for years. So our business model doesn’t really cater to the aftermarket, we have to do all the things internally between Corvette just like any other General Motors product. Our desire is to make the car as hack-proof as possible to protect our customers.”
