One of our customers from the Middle East has this sick looking blue SRT Viper that recently acquired some performance and aero mods as we featured before on our blog here. Sporting a Corsa Exhaust with an Agency Power intake, he also has his Agency Power carbon fiber aero upgrade. The V10 640bhp coupe is no slouch with its 6speed transmission. But how does it stack up against the worlds most out of the box race car, the 991 GT3 with 7speed PDK transmission. The 3.8L boxxer engine and lightweight chassis has no issues kicking ass either. So these guys went at it in a rolling race. You can hear the Viper miss a shift which is not a issue for the GT3, but still the huge displacement takes the win. For those that want to debate, what would happen in the corners!
