When transforming a street car to a race car you usually don’t start by reducing engine displacement, but that is exactly what Dodge engineers did building the SRT Dodge Viper GTS-R. ALMS (American LeMans Series) rules stipulate no more than 5.5 liter capacity motors; However, Dodge was able to submit and get approval to run their V10 motors in an 8.0 liter configuration by altering bore and stroke. The caveat was to run their V10 0.4 liters short of the street version 8.4 liter motor and installing an intake restrictor plate.
The normally aspirated 8.4 liter V-10 from the street legal SRT Dodge Viper GTS puts out an astounding 640 hp and 600 ft-lb of torque. To compensate for the reduction in hp, engineers attacked the problem with a weight reduction plan along with some aero dynamic alterations. I can’t wait to see this Viper battle it out against Ferrari, Porsche, Corvette and 2011’s Team Champion BMW GT2 in the 2013 season.
