I know im in a supra forum but does anyone have any idea how much rwhp a stock 2006 dodge viper coupe makes. I know it makes 510hp at the crank but I dont know how much at the rear wheels. Reason i wanna kknow is because hennessey has a twin turbocharger that I wanna get that makes a claimed 100hp and I wanna know what I'm starting out with. BTW I plan on getting the car and that is why I havent takin it to a dyno yet.
