Sorry, only had mine to 160mph at rev-limit in 4th. Most peeps will quote 190-192ish. One mag had it to 202mph but if that was true they'd be doing more high-speed SRT-10/Ford GT high speed shoot-out articles. Remember, top speed is achieved in 5th as there's not enough torque being multiplied by 6th gear to compensate for rolling and wind resistance.belvedere383 said:What is the top speed of a stock srt-10 viper. Note: don't give me the factory specs. Please, iwas wondering if anyone has found what an actual person has done in it.
