Apparently Viper owners weren't killing themselves fast enough.
While factory forced induction may remain elusive when it comes to America's big-ass V10-powered supercar, Arrow Racing Engines and The Viper Exchange have a solution. The two companies worked with Dodge on a set of new performance packages for the car, and this is the closest you're going to get to extra factory power. There will be three packages offered, with Stage 1 being a reflashed PCM that adds 20 to 25 horsepower to the 645 hp the 2015 Viper comes with.
The price on the Stage 1 package is $1,100, which probably seems a bit steep considering you might not even feel a power gain that small. Stage 2 is where things start to get serious, with new heads and cams that bring the horsepower total up to 733. And finally, there is Stage 3, which adds a 4.3-liter supercharger that brings the horsepower rating up to 895, as well as 800 lb-ft of torque. We don't have prices for Stage 2 or 3, but if the Stage 1 price is anything to go on, it'll probably be pretty steep. That said, the price of the actual car was recently reduced, making it easier to justify spending the money.
