Stock Chevrolet Corvette ZR1 runs in the 10’s

October 14th, 2009

The first stock Chevrolet Corvette ZR1 finally made it into the 10’s this past weekend at a private drag strip rental at Maryland International Raceway. With some great weather and a density altitude (DA) of -350 feet, this bone stock ZR1, including stock tires ran an impressive 10.85 @ 129.89 MPH with Racerns driving the car. Later on during the day a set of 18″ rear wheels with drag radials were installed on the ZR1 and it ran a 10.73 @ 132.46 MPH with Ranger driving the car.

It’s interesting to note the 60′ times for these slips, the run with stock tires pulled a 1.708 and with drag radials it pulled a 1.72, no improvement from the drag radials. By listening to the videos, it sounds like the quicker shifting by Ranger resulted in the better ET and MPH even though the 60′ time was a bit higher. It’s also possible that the drag radial setup had a different overall diameter resulting in a slight gearing change could have some effects as well when comparing the runs. Either way, congrats to both drivers for some excellent well documented runs! We expect some further improvements as the weather continues to cool and more ZR1s start hitting the track, the ZR1 certainly appears to be capable of mid 10’s in stock form.

    Only a few passes were made on the drag radials as most of the day was spent on running on stock tires. Ranger only took 3 passes (hot lapped in a row)and every one was a 10.73x. He did pull 1.68 60′ time on his last pass but the car fell off up top a little and had a trap of 131.95 mph and the ET was a 10.736. A little more work on the drag radial launch should net a 10.5x time we think.
