RC:
1. Not sure what you mean: As far as I remember, only the manual equipped pre-facelift 997 Turbo (there was no Turbo S) had a mechanical diff.. The mechanical diff. was part of the PTV package on the facelift 997 Turbo and Turbo S. Maybe I didn't understand your question?! ![yes](http://www.rennteam.com/staticimages/graemlins/shrug.gif)
2. The "old" 997 Turbo S was 173.241,00 EUR (incl. 19% VAT) in Germany, the new 991 Turbo S is 195.256,00 EUR (incl. 19% VAT).
RC based on facts here in Brazil:
the best result we got for a 997.2TT with ecu, full exhaust and intakes was from 100-200km/h 6.8sec
the 997.2TTS with same setup, ecu, exhaust + intakes, did 100-200km/h in 6.3sec
tests with RACELOGIC
it has to be something mechanical too....
