The Nismo weighs more than the Turbo S: 1720 / 1600 kg
That puts this result a little bit into perspective, but it is commonly recognized that it's need 600 PS to reach min. 10 sec in 0-200 km/h test.

Good info Rob,
shocking that the GT2 beat 991TTS in 1/4mile. It appears by the numbers next to the car that it had stock power of only 530hp. How did he launch it that well with RWD and shift it that well with a manual vs AWD and PDK in the TTS. He had to shift to at least 4th gear. I had a my GT2 modified to around 620hp and 11.1 was the best I could do on my Vbox and I tried over and over again.

 

That's right, I've written its nominal power on stock, but don't know, what this GT2 has build in.
So, your experiences are an indication, that this purple color GT2 is heavily changed.

Here we go:
10.818 s - 1515 kg - 997 GT2 (??? PS / ??? Nm)
10.821 s - 1600 kg - 991 Turbo S (nom. 560 PS / 700 Nm [Overboost: 750 Nm, Sport Plus], measured 607 PS / 784 Nm "Sport Auto" Car Magazine)

There’s a new Turbo, so the seventh-gen über-911 has rear-wheel steering, adaptive aerodynamics and a faster-acting four-wheel-drive system, while the Turbo S version (tested here) adds an active anti-roll system, dynamic engine mounts, ceramic brakes, and an additional 38bhp and 30lb ft.

The 991 Turbo S will lap the ’Ring in 7:27 (‘naturally with standard production tyres,’ says Porsche).
