This long awaited ZR1 finally made it to Dyno-Comp for the first round of upgrades. Bone stock this ZR1 made an impressive 500 wheel HP and 495+ peak torque at a brutal 3500 RPM. Converting to “Flywheel HP” on our Dyno-Dynamics Dynamometer, this equates to 620 HP and 613 TQ vs. Chevrolet’s claim of 620 HP and 595 TQ which is not too optimistic on their part!
So what’s in store for the MOST powerful production Corvette ever built?
Dyno-Comp plans to take this ZR1 to the 770-800 HP mark!!! Since this ZR1 was still in it’s “break-in” period, Dyno-Comp decided to start with an exhaust system upgrade. The Corsa Sport exhaust system yielded another 38+ wheel TQ coming it at 3500 RPM and another 24-25 wheel HP across the entire RPM range.
“So what’s the 0-1000 Club, you ask?”
If you analyze the above dyno chart, the scale is 0-1000 HP and 0-1000 TQ.
Once a car goes over 500 Wheel HP, we must change the scale on the chart from 0-500 to 0-1000.
Note: The minor graduations are now 20 HP each.
