Hennessey is brilliant and has worked on some of the top cars including the Viper, Mustang, and the Veyron. His most recent accomplishes are the GT-R, IS F, and ZR1. He has created these cars to be some of the best and most powerful on the road. Hennessey stated this week that he has already begun working on packages that will improve these cars (if that’s possible) and make them more powerful. (more…)
It has been a month since Dodge revealed the Challenger SRT8 and already Hennessey has released a performance package – which has been called the SRT700. In this package Hennessey has added extra cubes to the V8 6.1 liter that has a stroker crankshaft and can pump out 426ci. (more…)
The 2008 Hennessey Venom 650R package is rumored to be faster and more powerful than its previous predecessors. John Hennessey has promised to makeover any 2008 Viper SR10 and transform it into the specifications of a Venom 650R at the Hennessey Performance Engineering plant located in Sealy, Texas.
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. (more…)
