VIDEO: Dodge Viper ACR-X Engine on the Dyno

Production of the Dodge Viper is set to end this year - but the car's future won't end there. Last year, Ralph Gilles, CEO of the Dodge car brand, said that production of the current Viper will end in July of this year.

He said then that a run of 500 final edition Vipers will be produced before that date, and that they will be the “most special Vipers ever.” The ACR-X is one of those Vipers, a hardcore, track-only (not street legal) version of the Viper.

According to Gilles, Dodge wants to end with a bang, preserve the value of the current generation car until a new vehicle (which is being developed right now, in partnership with "Italian operations") is ready in 2012. Long wait? Yes, but the important thing is that we are getting a new Viper at all.

Dodge released this video showing off the ACR-X, putting the engine on the dynometer. It makes 640 horsepower, up 40 from the stock engine, by having 5-into-1 exhaust headers and no catalytic converters, along with other changes. Check out the the red-hot headers below.
