The guys at Late Model Racecraft have been among the forefront of shops that specialize in LS and LT-engine tuning with many of their creations shared on YouTube. Here’s a new video they have shared featuring a roll-race matchup with the C7 ZR1 vs a C6 ZR1. This has been a matchup often talked about but rarely seen so belt in and let’s see what happens!
LMR doesn’t offer any specs of the cars other than saying they opened up the C7 ZR1s exhaust with an X pipe install. From the factory, the C7 has 755-hp and 715 lb-ft of torque but weighs in at 3,560 pounds. That’s 117 horsepower and 111 lb-ft torque more than a stock 3,373-pound C6 Corvette ZR1’s 638-horsepower and 604 lb-ft of torque.
The roll-race takes place on a highway with the cars rolling at 55 mph. As the go is signaled with the traditional three blasts of the horn, the C7 ZR1 leaps out in front and never looks back. The race is captured from both perspectives and the C7’s Performance Data Recorder shows ZTK-equipped car at nearly 150 mph before the brake lights come on.
From LMR on YouTube:
We finished up an X pipe install on this brand new 2019 ZR1! So what better way to see the results other than putting it against a C6 ZR1! Check out the results for yourself!
As I watched this video I found myself rooting for the underdog. I wonder if these two namesakes separated by 10 years and two generations had a go at a top speed event if the C6 could close the gap once the ZTK high-wing becomes a drag. Now that would be an interesting race!
