Hennessey Supercharges the Viper to Hellcat-Trolling 808 HP with Flame-Spitting

Those who found the Gen 5 (current model) Dodge Viper as lacking power could always turn to Hennessey Performance, which delivered an all-motor 700 hp upgrade, or, turning to forced induction, a 1,120 hp twin-turbo boost (here's our story on the matter).

Well, from now on, the Texan developer can also satisfy your supercharger Viper desires and it's all thanks to the Venom 800 package. As you've already figured out, this means the SRT supercar jumps from 645 to 800 horses - it's actually a Hellcat-trolling 808 hp.

With the 8.4-liter V10 having been left in stock condition, the Lone Star State developer may have installed a blower, but stuck to a reasonable 5 psi boost pressure. Even so, the generously-sized engine compartment of the snake now also accommodates an intercooler, high-flow injectors, as well as an engine management system upgrade. The 3-inch stainless steel exhaust comes as bonus, one that spits flames from time to time.

How does the added muscle translate into performance numbers?


Thanks to the added muscle, the Dodge Viper can now complete the 0 to 60 mph spring in 2.9 seconds, while dealing with quarter mile chores in 10.5 seconds at 143 mph - since Hennessey explains the "best acceleration times are attained using optional drag radial tires on a prepped dragstrip," we expect these ingredients to have been used for achieving the times mentioned above.

Bragging fans will be pleased to find out the Venom 800 badges found on the exterior of the supercar are mixed with serial-numbered dash and engine plaques, as well as with Hennessey-branded floormats.

As for the warranty, Hennessey explains the Venom 800 package will watch your back for one year or 12,000 miles of heavy-foot driving.

The tuner was kind enough to also provide a dyno video of the beast. And the clip brings us a soundtrack that's so American we wish the footage would've been here for the 4th of July.
