In a little bit of a dog fight with one of my viper pals, who thinks the viper is the end and be all of muscle. Was telling me that vipers can get up to 2000 BHP with aftermarket turbos and superchargers and that I should enjoy my viper more than the FGT, (right). What is the max range forum members get with attempts to increase BHP? What do these twin turbos-supercharged Hennessey FGTs run for BHP?
