I put my Viper on a dyno today to see what kind of horsepower and torque it was making at the wheels. It supposedly makes 600 horsepower at the crank and I’ve heard reports of 530 to 560 horsepower at the wheels, so I was curious to see what mine actually makes. Turns out it’s 533 horsepower and 504 lb-ft of torque. Considering it was a little warm out and decently humid, that’s not bad!
