The article featured this week from Hotcars.com
about the new upgrade for the Corvette ZR1 from Hennessey begins with
the short list of cars that have 1,200 horsepower. The world's fastest is the
Koenigsegg Agera RS, which boasts a startling 1,341 hp when running on
race-grade fuel. Then there's also the Bugatti Veyron Grand Sport Vitesse, the
world's fastest car previously with its 1,200 horsepower and 1,100 lb-ft of torque.
Hennessey even has their very own Venom GT, touting bragging rights to 1,244
horsepower, and what many in our circles here at West Chevy and
beyond regard unofficially as the fastest-accelerating car on Earth.
Any Chevy fan should be absolutely thinking twice
at the possibility of picking up something this fast at their local Chevy
dealer for just a fraction of the price, and with the Hennessey 1,200
horsepower upgrade package for the C7-Generation ZR1, it's possible. This means
of making a Corvette a hypercar is cause to celebrate: any chance at all of
getting to 1,200 horses is a longshot in the beginning during the drawing board
stage, and the list of duties to achieve success was long.
Hennessey had to take on upgrading the
supercharger, acquiring an entirely new throttle body, upgrade both lower and
upper pulleys, make a custom camshaft, port the cylinder's heads, upgrade
valves, springs, and retainers, as well as get stronger pushrods to
appropriately take on all that power. Midpipes, stainless steel headers, and a
brand new catalytic converter are also all part of the package. Very detailed
dyno and testing, a strengthened 8-speed transmission, and ECU upgrades are
also part of this very high-achieving tweak, and most professionals are assuming
that E85 fuel is what's needed, since 93 octane seems to top out at 1,100 hp.
Unique Hennessey badging, serialized plaques and floor mats are all included as
well, on top of a 3-year, 36,000-mile warranty.
You can check out all of the fine details here on the official Hennessey website, where there
are also some amazing pictures of the ZR1 in performance mode at dusk. If you
happen to have the 7-speed manual, the transmission does not require an
upgrade, and you'll be flying forward with glee in no time flat. The staff of Car
and Driver took the 2019 Corvette ZR1 for a spin at the Texas Mile and
went 183.3 mph, and still loved how the car possesses enough daily-driver
traits to make it sensible on any street. They ran the Mill with traction and
stability control on, but still metered the throttle before second gear.
Just three years ago when the Z-6 hit the road,
650 horsepower was plenty, but as every year brings new challenges and
adventures, this exciting revelation from the Hennessey team should literally
be a “mover of mountains” and a tremendously track-tuned great ball of fire!
