we need evidence of a 997TT FT with PDK. During FL launch 2 months ago porsche insisted that the current PDK cannot handle the torque of the TT or GT3

If Nissan can build one that copes with the similar torque, then surely Porsche can to. Also Bugatti's gearbox copes with way more torque in it's DSG box.
Porsche will definitely be building one, as right now they are behind in the technology game.

A future Di 997tt at 1620kg with 510hp/680NM would quite probably be able to achieve 10.Xs 0-200kph times due to this PDK box with the uninterrupted flow of torque...
a typical manual change can take about 1s from interrupting forward G force to resuming full G force in the next gear (see trace below) so if the PDK reduces this to 0.2s the saving over 3 gearchanges to 200kph could be 2+seconds hence 0-200kph in low 10s mark with a lot less headline torque - its bloody voodoo I tell you

It is the seamless way these PDKs deliver the torque (and maintain the boost level) virtually eliminating any drop off during changes combined with closely stacked ratios which allow the high end of the torque curve (ie higher power levels) to be utilised, which seems to really give them the edge compared to tip/manual.

The Ferrari 599 has amazing acceleration for its weight, 1750kg, 620PS/608NM and has been timed 0-200 10.2s 0-250 16.6s which is about the same as the manual boxed Cargraphic 624PS 997tt which weighed 149Xkg - these fancy boxes certainly give the numbers....

Questions for the Nring "experts" here please:
Have both versions of the Facelift 997S's, PDK versus manual, been tested by Sport Auto at Nring? If so what's the time difference?
Has auto-manual type tranny been conclusive been proven to be faster than manual at Nring? For example, for other cars with dual trannies available, like F430 and Lambo, is the F1 tranny faster than manual? If so, by how much in general?
TIA.

Sportauto did only test the manual version of the 997TT. We can only speculate about the performance of the 997TT Tip. My guess: Tip would be ca. 2-4 seconds slower than manual around the NBR-NS Any other views?

Thanks Markus. How about the Facelift Non-Turbo 997, has HVS driven PDK versus manual at Nring yet? If so, what's the verdict? Is PDK faster as Porsche claims, 8 seconds I think?
