Hennessey 2008 Viper SRT10 Adds 78 horsepower

Already before its launch, Dodge/Chrysler tuning firm, Hennessey Performance Engineering, are targeting the upcoming 2009 Corvette Blue Devil ZR-1. For the 2008 Viper SRT10, Hennessey presents an engine upgrade package called Venom 650R, with a power increase of 78 hp to 678hp which results in 0 to 150 mph dropping by a huge 1.5 seconds, 15.5 sec. versus 17.0 sec. for stock Viper. Hennessey achieves these gains by simply improving breathing with custom fabricated 5 to 1 stainless exhaust headers, aftermarket catalytic converters which are followed by full stainless 3-inch mid pipes and high-flow mufflers. On the intake side, just the addition of a K&N high-flow air filter was added.

Other items include light-weight cross-drilled brake rotors saving 8 lbs. per corner, Hennessey Venom Power floor mats, exclusive Hennessey Venom 650R exterior badges and a serial numbered plaque located in the cockpit and under the hood.

Available through specially selected Dodge dealerships the upgrade costs $8950 and includes professional installation and dyno testing. The 650R will only have 200 units made and comes with a full 3 year / 36,000 mile Hennessey warranty that will cover the modifications performed to the vehicle.

Press Release

Hennessey adds 78 horsepower to the 2008 Viper SRT10 to Combat Upcoming 2009 Corvette Blue Devil ZR-1

Hennessey Performance Engineering (HPE) today announced that it is introducing the company's first high-performance upgrade system for the new 2008 Dodge Viper SRT10. Known as the Venom 650R, the engine modifications increase by 78 horsepower giving the Viper the ability to accelerate from 0 to 150 mph 1.5 seconds quicker (15.5 sec. versus 17.0 sec.) than the already factory-fast 2008 Viper that offers a stout 600 horsepower.

The Venom 650R package consists of custom fabricated long tube stainless-steel exhaust headers with 1 7/8-inch primary tubes flowing into 5-to-1 merge collectors. From there, the spent exhaust gases flow through aftermarket catalytic converters before traveling through a full 3-inch stainless-steel exhaust system fit with high-flow stainless-steel mufflers. Other performance upgrades include: K&N high-flow air filter element, 2-piece light-weight cross-drilled brake rotors (saving 8 lbs per corner), professional installation, dyno testing, Hennessey Venom Power floor mats and exclusive Hennessey Venom 650R exterior badges. Each Venom 650R has a serial numbered plaque located in the cockpit and under the hood. Rounding out the package, the Venom 650R will carry a full 3 year / 36,000 mile Hennessey warranty that will cover the modifications performed to the vehicle.

HPE plans to build 200 units for the 2008 model year. Many of these cars will be available through an exclusive Hennessey dealer network comprised of high-performance minded Dodge dealers.

The Hennessey Venom 650R upgrade package gives 2008 Viper owners the option to fend off any Corvette Blue Devil ZR-1s that they might encounter in the coming New Year.
