overboost is available for both trannys.
it is available between 2000 and 5000 rpm and increases torque to 680 nm by raising turbo boost by 0.2 bar.
it also raises horsepower output in that given powerband in relation to no overboost cars.
it does not raise max horsepower, as this is reached at 6000 rpm where overboost is not available anymore.
the time limit of 10 secs. is basically theoretical as it is very unlikely, that you will floor it and spend more than ten seconds flooring it between 2000- 5000 rpm, so basically it is an always on feature.
personally speaking, they should have just raised the max. boost by those 0.2 bar throughout the whole rev range. this would probably resulted in the magic 500 hp figure and even more vicious acceleration.
then again, they want to sell us a turbo s in the future dont they...........
