Twin turbo Viper makes over 1300HP on the stock engine!
You can’t talk about fast vipers without talking about Calvo Motorsports! They are on the cutting edge when it comes to pushing Vipers to the limit on a daily basis. This is just ridiculous, not many people would even think about putting this much power through a stock motor! They take it to one of the best proving grounds to see what it’s got! They put it up against a Supra and an Evo, and it becomes a drivers race, but the Viper ends up freight training them!
