Rumors have been floating around for years about a potential supercharged Viper.
It appears that it is finally happening, but it is not a factory built package. Instead, it was developed by Arrow Racing, which has Chrysler’s permission to modify the computer programming. It will be sold at the largest Viper dealer in the country, The Viper Exchange a/k/a Tomball Dodge.
There are actually three different packages:
Computer (PCM) only,
Computer, heads, and fixed cam
Computer and low-profile, Rootes-style supercharger.
Viper Exchange told us that the PCM can handle all 3 packages together. There are no power numbers given for the heads/cam combo with the supercharger added, or, the supercharger package includes the stage 1 and 2 kit. One would assume that the PCM would be part of both the stage 2 and 3 packages as well, as a recalibrated PCM would be needed to get the most out of either combo.
The PCM only package provides a 20-25 HP boost, with a boost in torque over the whole power band. The heads and cam package provides 75-80 hp peak gains, with significant gains from 3000 rpm on up, and again, a significant boost to torque throughout that RPM band.
The supercharger package, also known as “the Sledgehammer,” brings around a 250hp gain, and it looks to be well over 200 ft/lbs of torque gain as well. Sledgehammer indeed!
So, if 645 horsepower is not enough for you, it appears that the combination of the The Viper Exchange and Arrow Racing have the answer for your 2013-2015 Dodge Viper.
This has been a big week for The Viper Exchange owner Ben Keating; first, one of Vipers he co-sponsors won the GTD class in the 24 hours of Daytona, placing 13th overall, and now this huge announcement for the Gen V owners. Ben has many reasons to smile, and has given Viper owners everywhere reason to smile as well.
