Wow! I thought my GT dyno #'s were good. I just added a supercharger and exhaust to my 06 SRT-10 Coupe and got a 675.18hp with 609 torque and 8.21 boost after dyno at the rear wheels - uncorrected. If the standard loss for the Viper was added that would put it at about 794hp at the flywheel! :willy :eek
