A local guy here has a viper GTS I believe with a twin turbo kit on it. He says its a hennesey turbo kit, but can you just buy the turbo kit alone? I thought you had to buy a whole package or something. He puts down around 800whp he said on 10lbs, but I have never seen a dyno sheet. He is a pretty cool guy and races people from time to time. In this video I have here he is racing a fully built 240sx with big tires on the back. The 240 runs low 11's in the quarter. In this race the viper is on street tires and 4lbs.

Viper basically gets destroyed, but besides all that the main question is can you really just buy a hennesey turbo kit? Would he have to upgrade the internals at all? I love the car and wish I had one myself...just trying to do some research. Thanks
