With the 997 Turbo putting out 480 hp already, the GT2 should be good for at least 500. In fact 520-540 are the numbers we keep coming across. Although it looks a lot like the Turbo, the GT2 has a few detail changes, like the lack of fog lamps and a larger rear spoiler. Couple that with the expected weight loss associated with the switch from awd to rwd, and this should be another super Porsche worthy of the Widowmaker label. But the guys at World Car Fans point out that it is the sound that will really set this model apart from lesser 911s. Caught testing at the Nürburgring, they said it could be heard almost half way around the track. But it was music to their ears, as is this report of further development on the GT2 to ours.
