It's hard putting a price on awesome yet somehow, Hennessey->ke1863 never fails to deliver. The US aftermarket company has time and again developed some of the wildest tuning projects imaginable and its no different with its program for the 2013 SRT Viper->ke4220.

Who cares if the Viper's sales are lagging; when you have Hennessey develop a program like the Venom 700R, you're going to be tripping over yourselves to scoop up a Viper and get the project done.

On its own, the SRT Viper is capable of producing 640 horsepower and 600 pound-feet of torque, good enough to hit 0-60 mph in 3.3 seconds to go with a top speed of 206 mph. But with the Venom 700R program installed, the Viper's output goes up to an incredible 705 horsepower and 695 pound-feet of torque, numbers that allow it to hit 0-60 mph in 3.1 seconds to go with a top speed of 216 mph.

That's crazy in every imaginable way you look at it. Then again, Hennessey has made a habit of turning anything it builds into something crazy.

Hennessey's program for the 2013 SRT Viper is insane all the way around. While the cosmetic changes are limited to a carbon fiber aerodynamic kit that includes new spoilers and new splitters, the performance modification is all sorts of serious business.

Thanks to the addition of high-flow cylinder heads and catalytic converters, a new stainless steel exhaust system with 3-inch tubes, a K&N air filter, and an ECU remap, Hennessey was able to improve the Viper's output to 725 horsepower and 695 pound-feet of torque, allowing it to hit 0-60 mph in 3.1 seconds to go with a top speed of 216 mph.
