997 Turbo "Sport Chrono Turbo package"
Analogue and digital stopwatch on the switch panel.
Sport mode for engine, chassis (PASM) and transmission (Tiptronic S) incl. Sport button for activation.
Performance display in the PCM
Individual memory
Regarding "Overboost function"
NOT a simple feat for prospective tuners
The higher boost pressure gives rise to a sudden substantial increase in the mechanical stress on the components and, above all, in heat-induced stress.
This results above all from the continually rising charge air and combustion chamber temperatures.
With regard to these processes and the maximum possible stress on the components, the Overboost function is limited to 10 seconds.
After this period, the original full-load pressure without Overboost is set.
As soon as the stress on the engine is relieved briefly as a result of closure of the throttle valve (e.g. after gear-shifting), the Overboost function can be activated again.
The Sport Chrono Turbo package is complemented by more agile all-wheel drive tuning and, in conjuction with optional Tiptronic S, by a modified starting programme.
When the Sport button is pressed, drive-off is effected in 1st gear, instead of 2nd gear.
