Dodge unveiled a special-edition model of the Challenger Redeye Widebody last year called the Challenger Super Stock. The car comes with the famous 6.2-liter, V-8 supercharged HEMI engine that churns out over 800 horses. Hennessey brought this car over to its factory and equipped it with its HPE1000 Performance Upgrade package. The result? 1,000+ horses on paper, but around 800 horses on the dyno. In Hennessey’s defense, it is still more than the Challenger Super Stock’s dyno figures.

How Much More Power Does The HPE1000 Package Supplement?

The Challenger Super Stock in the ‘stock’ condition makes 807 horses and 707 pound-feet of twist from its 6.2-liter, V-8 supercharged HEMI engine. Power is sent to the rear wheels via an eight-speed TorqueFlite automatic gearbox.

Hennessey equipped the HPE1000 performance upgrade package that bumps up these figures to 1,035 horses at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm.

A dyno test, however, revealed that the car lays down 810 horses and 732 pound-feet of twist at the rear wheels. These figures are 110 rear-wheel horsepower and 84 pound-feet of rear-wheel torque more than the standard model.

The stock Super Stock takes 3.25 seconds to sprint to 60 mph from rest, but Hennessey hasn’t revealed the figures for this one. It will certainly be quicker, perhaps clocking times in the whereabouts of three seconds.

A lot of other modifications include:

  • Lower and Upper Pulley Upgrade
  • Ported Supercharger Snout
  • Stainless-Steel Long Tube Headers
  • High-Flow Catalytic Converters, Mid Pipes, Fuel Injectors, and Air Induction System
  • Crank Case Ventilation System
  • HPE Calibration Upgrade

Are There Any Changes To The Exterior Or Interior?

This package is all about performance upgrades, so there are no changes made to the cabin or the body. A few Hennessey and HPE1000 exterior badges, however, are placed. This isn’t a limited-edition package, but serial-numbered plaques are also pasted.

The Challenger Super Stock is based on the Redeye Widebody, so it looks exactly the same as that one, but with more performance. Fun fact: Have you ever wondered why an 800+ horsepower beast is called “Super Stock”? The name comes from the Super Stock class of vehicles in drag racing. These were essentially sleeper cars - vehicles that looks regular but were hardcore racers at heart.

Conclusion
