Allpar reader “kdaviper” wrote, “A fifth-generation Viper engine was spotted at Arrow Racing, with a Paxton-style supercharger strapped to it. This could mean that SRT is planning on supercharging the Viper V-10 for production, or that Mopar is developing a bolt-on supercharger kit, or possibly that SRT is working on an engine for a Viper racing car (possibly formula-D?) It may also mean absolutely nothing.”
JRS200x had previously written that Arrow Racing was setting up a supercharger for a new model of the SRT (née Dodge) Viper. Both sources have been reliable in past predictions, though any project under development is subject to change.
