We’re pretty sure that if you want to buy an American sports car this year, you may opt for the SRT Viper, and not the new Corvette Stingray. While Chevrolet failed to capture the usual Corvette allure, SRT did an amazing job in developing an awesome sports car - no slight to the Corvette, of course.
The SRT Viper is powered by a new 8.4-liter, all-aluminum V-10 overhead-valve engine that will deliver a total of 640 horsepower and 600 pound-feet of torque. The new engine will be mated to an improved Tremec TR6060 six-speed manual transmission.
According to Hennessey Performance, which was the latest one to dyno test the 2013 Viper, the new Viper develops a total of 558 rear wheel horsepower and 515 pound-feet of torque. So, how do we get from here to the numbers announced by SRT? Well, simply add forced induction; In fact, you will obtain almost double than SRT announced with some pressurized air flowing through the intake.
