Could anyone please offer technical information and/or specifications, as to how the overboost feature operates?
My understanding is that typically, overboost holds the peak torque for longer in the RPM cycle; but it generally does not go over the peak? Maybe this is not correct?
Whereas for the T5, the peak torque of 266 is increased to 295 during the cycle. Hence, the torque is both greater and held for a longer period during the overboost burst? Is this correct??
Regarding overboost, I am very curious as to what exactly happens, how it is triggered, how it is released,...
Also, why didn't Volvo combine selectable shifting with the sport mode overboost? (you can only select a precise gear while in "D" not "S"? And is there a Winder mode "W" to do the inverse of the "S" mode?? )
Volvo seems to be nicely pushing the envelop on this technology, any information is much appreciated; thanks.
