the challenge will be getting the new motor to work with PDK IMO
Without even pondering the reliability or otherwise of tuned non Mezger engines the real challenge for the tuners seems to be getting all the other electronically controlled systems working together.
The PDK is the key to the amazing acceleration numbers of the Dfi turbo motor and the electronics to make it work properly, coordinating the boost with the lightening fast changes is only going to be possible by using the heavily (and expensively) developed Porsche electronics.
Apart from PDK, the electronic traction control and PASM and 4WD systems are so woven into the engine electronics that the tuner's options are pretty limited if they want to maintain factory safe guards and IMO for over 900NM torque the factory "nannies" are essential although the 996 turbo 4WD system seems perfectly adequate, RWD only renders TC AND PASM obligatory.
The Carerra GT only has TC, it was developed just before the PASM was introduced and IMO this car is pretty dangerous even with only ~700NM when DRIVEN on anything but dry, flat non cambered roads, it would have really benefitted by having PASM and those feeling heroic could always swith if off
I cannot imagine that Ruf will be able to get his V8 to be able to work with the PDK, more likely he will use some sort of sequential - remember in the 90s he pioneered that clutchless gear change for the 993 turbos he did, it never really took off (I think there were reliability problems) but Ruf is not afraid of doing his own thing so if he does turbo charge his V8 I'm sure it will be a pretty special package
