Hennessey Performance recently got their first 2019 Corvette ZR1 as the Texas Tuning company plans to offer their HPE1000 package for Chevrolet’s tip of the spear sportscar. But before they dive into the engine compartment, the Artic White Corvette ZR1 was put on the dyno and then taken out to the track for some baseline top speed runs.
The dyno results were mostly on-par with the various other tuners who have dyno’ed the ZR1. Hennessey shared the results of the dyno which shows 654 rear wheel hp and 645 rear wheel lb-ft of torque. That video is also on YouTube.
But this top speed video is the reason for this post as it’s not often you get to watch and listen to that LT5 V8 during wide-open throttle. We saw Jay Leno and Tadge Juechter do it first and then Chevy released their own official video showing the car’s average of 212 mph.
We see at the start of the video of the Arctic White ZR1 on a track. But once the top speed run commences, the focus is on the speedometer.
The first shifts of the automatic 8-speed happen quickly then takes its time as the RPMs climb. At the very end as the car hits 193 mph and the driver backs off, you can hear him say “Steady as rock”, most likely a reference to the handling and feel of the car at those speeds.
Hennessey’s HPE1000 ZR1 is expected to have a quarter mile time of 9.7 sec. @147 mph and a top speed of 200+ mph. HPE gets to that level of performance with a number of go-fast parts including a new high-flow supercharger, custom camshaft and opening up the airflow. As par for the course, the upgrades require the HPE Engine Management System.
And that’s something we have noted over the last few months is it appears that tuners are having difficulty gaining access to the ZR1’s computer that regulates the engine management functions. Chevrolet has put in place new security enhancements to block unauthorized hacking, and we have yet to hear from a tuner that has successfully broken through. We are sure Hennessey will put their considerable resoures to the task so stay tuned!
