The Dodge Viper is no stranger to speed or power … but a little extra can’t hurt. The previous owner of this ’98 Viper GTS added a Corsa exhaust system, Oliver Racing connecting rods, T&D Machine Products roller rockers and then topped off the 8.0-liter V10 with two Garrett turbochargers. The horsepower output nearly doubled with these modifications and the Centerforce Performance clutch sets the driver up for a smooth ride even at 891 horsepower. This ’98 Viper GTS has a secret under the hood, and is relatively affordable for the amount of power available. Let us know in the comments if this is your kind of garage addition!
