Earlier this month, Hennessey unveiled a Chevrolet Corvette ZR1 tuned to a massive 1,000 HP. More recently, that very same car was subjected to the quarter-mile test.
The ‘Vette completed the run in 9.79 seconds at 139 mph (224 km/h) thanks to the HPE1000 performance kit that has lifted the output of the supercharged 6.2-liter V8 by a massive 245 hp compared to the stock ZR1.
That’s been achieved by fitting many upgrades parts, like a new high-flow induction system, custom camshaft, ported cylinder heads, upgraded valve springs and retainers, new intake valves, bespoke exhaust valves, upgraded lifters and pushrods, a lower pulley upgrade, stainless steel headers and stainless steel midpipes, as well as a tuned ECU and high-flow catalytic converters.
Before demonstrating it at the drag strip, Hennessey tested it on the dyno, where the numbers were even crazier: 905 hp and 844 pound-feet (1,144 Nm) of torque at the wheels! Contrary to what some may think, that’s not overkill, as the car shows that it can cope with the massive output just fine. By the way, the 0-60 mph (0-96 km/h) seems to take less than 3 seconds.
Hennessey’s not done with the ZR1, though; not by a long shot. That’s because, a little while after unveiling the HPE1000, they released the HPE1200 kit that brings total output to 1,200 horsepower and 1,066 lb-ft (1,445 Nm) of torque. Guess that quarter-mile time is very soon going to drop even lower.
