It is a BS rumor. Prototypes were delivered but that does not mean anything regarding production for 2015. Chrysler receives and tests different technologies on a constant basis. That is how various components and vendors are evaluated. A majority of the stuff presented never sees the light of day.
It is my hope that Arrow was sending some supercharged engines over to be evaluated on Chrysler's dynos to see how durable the engine is with the supercharger system Arrow produced and put on the engines. It is also my hope that they pass muster well enough for Arrow to offer an aftermarket kit. Arrow, for those who do not know, has done all serious warranty repair work on Viper engines for many years. So a kit by them would be a top quality item.
