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.
