Now we’re happy to report that HPE has released a video of the same HPE1000-equipped 2019 Corvette ZR1 doing a sub-10-second quarter mile at 139 mph.
The HPE1000 package includes an upgraded supercharger pulley, a performance camshaft, ported cylinder heads, new valve springs and retainers, new intake and exhaust valves, upgraded lifters and pushrods, a full aftermarket exhaust and much more. Running on Shell V-Power 93 octane pump gas, the upgraded 6.2-liter supercharged V8 is good for 905 horsepower and 844 pound-feet of torque at the rear wheels.
These upgrades can be applied to C7 Corvette ZR1s with either the eight-speed automatic transmission or a seven-speed manual. Eight-speed cars will require some transmission strengthening upgrades, however, while the seven-speed can the torque from stock.
The HPE1000 2019 Corvette ZR1 shown in the quarter-mile video, which is embedded above, is equipped with the eight-speed automatic transmission. The automatic is the faster transmission at the drag strip and it shows, with the car easily clocking in at 9.79 at 139 mph. It could probably go faster, too. The driver didn’t launch the car particularly hard and it appears to be on street-legal rubber. This particular car also has the optional aerodynamics package, which creates more drag and thus slows the car down in the quarter-mile.
If for some reason the HPE1000 package is still too tame, HPE is also offering an HPE1200 package for the 2019 Corvette ZR1 as well. This upgrade kit requires more extreme modifications to the LT5 V8 engine, like a ported supercharger, new upper and lower pulleys and a high flow custom throttle body. HPE has yet to test this version at the drag strip.
