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!
