Hennessey Performance Puts a 2013 SRT Viper on the Dyno

The stock 640 hp SRT Viper is just not good enough for the folks at Hennessey Performance. So they added long-tube headers, a 3-inch exhaust, K&N filter and high-flow cylinder heads and saw an increase of 85 horsepower to 725 hp and 695 lb-ft of torque! I’m sure they won’t stop there but you can check the out video after the jump!
