The Chevrolet C8 Corvette is proving to be seriously popular, and Chevy seems to be struggling somewhat to keep up with demand. The reason for this high demand? The C8 is just so damn good. This mid-engine American sports car punches way above its weight and is a serious performance bargain. Despite GM's best efforts to thwart tuners from messing around with the Corvette's powertrain, the aftermarket has been pushing massive power figures mostly thanks to turbocharging, and these tuned C8s have been setting crazy quarter-mile times. We recently covered YouTuber Emelia Hartford's unofficial quarter-mile record run of 9.36 seconds at 147 mph, but the same tuners who helped her out have now beaten that time in a big way.

Extreme Turbo Systems is a market leader in turbo kits for the C8 Corvette, and has helped numerous C8 owners, including Emelia Hartford push for ever improving numbers on the quarter-mile. In the short video clip, we get to see a customer's C8 breaking the world record during a testing session at an undisclosed track. The run is recorded in portrait on a phone, which does not help legitimize the record-breaking run, but if the time slips are anything to go on, ETS have surely done it. In the video we get a glimpse of a timeslip for the 'previous run' which shows a time of 9.19 seconds at 160 mph. The slip also shows a reaction time of 0.649 seconds, and a sixty-foot time of 1.421 seconds.

The supposed record-breaking run's time slip shows 9.050 seconds at 159.53 mph with a reaction time of 1.621 seconds, and a sixty foot of 1.443. If these slips can be trusted, then we have a new fastest C8 Corvette. This makes things a bit awkward for Emelia Hartford, who's car and face are plastered all over Motul billboards across the US claiming the world record. Time to step it up Emelia.
