9ff, the manic Porsche tuner that created the 409km/h GT9 had put their hands on the 911 GT2, itself a Turbocharged beast that not many on the streets could be put up against, had perhaps watched Top Gear's test between the GT2 and Gallardo LP560-4 and decides that Clarkson weren't terrified enough, had gone down dirty and to business creating this 670hp GT2 with a few tweaks on the regular stuffs (exhausts, intake, exhaust, ECU etc). An even more crazy thing is, 9ff says this is the 'low' powered version, a 910hp version is coming up.
