Hennessey’s 1,000 horsepower Corvette ZR1 upgrade can run a quarter-mile faster than a Dodge Demon.
You can do a lot with a thousand horsepower. You can drive around the Nurburgring really fast, or you can tow a small house uphill. But around where Hennessey lives, 1,000 horsepower is meant to do one thing: go very fast in a straight line, one quarter-mile at a time.
To whit, we have the 1,000 hp HPE1000 Chevrolet Corvette ZR1. As Hennessey’s naming convention implies, the 6.2-L supercharged V8 has been tuned to produce 1,000 hp as well as 966 lb-ft of torque. Power is sent to the rear wheels via either a 7-speed manual or 8-speed automatic transmission. Top speed is said to be over 230 mph.
But how fast can it accelerate? Well, Hennessey says it can shoot from zero to sixty in just 2.3 seconds, which is about the same time it takes for a Dodge Demon. Quarter-mile times have been recorded as low as 9.4 seconds, which is even faster than the Dodge Demon.
The latest video from Hennessey provides some proof as to the HPE1000’s power. Wearing new drag radials, the HPE1000 completes a burnout and then catapults to the quarter-mile in just 9.79 seconds finishing at 139 mph. That’s not quite as fast as 9.4 seconds, but we can just assume that Hennessey was able to do it at some point and just forgot to capture it on camera.
Getting to 1,000 horses from the original car’s 755 hp is no easy feat. Upgrades include a high-flow air induction system, custom camshaft, ported cylinder heads, new stainless steel headers and midpipes, as well as upgraded valves, springs, lifters, and pushrods.
If you go for the 8-speed automatic transmission, the gears will need to be replaced with ones that can handle 1,000 horses otherwise the whole thing will explode the first time it shifts. The 7-speed manual, on the other hand, requires no such upgrades.
As with all Hennessey products, you get a bunch of badges, plaques, and floor mats, as well as a 3-year or 36,000-mile warranty. Corvettes can be grabbed for a steal these days, so getting one uprated to hypercar levels of power shouldn’t cost as much as Koenigsegg.
