It’s quite a tough challenge to perfect a flawless sports car like the Porsche 911 GT2 RS. BBi Autosport from the USA also took motorsports developments as a paragon for their Porsche 911 GT2 RS project. But the Americans from BBi Autosport made it a little more American. They were looking for more boost first and they found it… Powerplay – the Porsche is not called by chance “BBi VMAX GT2 RS” The “BBi VMAX GT2 RS Porsche”, which recently impressed at the charity event, Sun Valley Tour de Force, a sports car meeting in Idaho, produces well over 700 hp. The 3.8-liter Biturbo six-cylinder boxer engine gets more power from two larger Borg Warner VTG turbos. BBi redesigned the superchargers with new 7+7 gas turbine wheels and nine blades on the exhaust side.
