Torque of what?
Takes over what?
Do you not understand what torque is or what BHP is?
Torque is a figure saying how hard something is applying a force, BHP is saying BOTH how hard its applying a force AND how often.
As an example, take cups of water used to fill a punch bowl.
The bowl getting more full = the car acceleating
The bowl getting less full = the car decelerating
BHP would say how much water is moved into the bowl, so maybe "20 litres a minute" for example, torque would just be the size of the cup, to the punch bowl it doesnt care i it gets 40 half litre cups, or 80 quarter litre cups, its still the same amount of fluid on the way in.
On that example, the faster you are trying to go, the quicker the punters are emptying the punch bowl.
So 200mph might require 80 litres of water a minute, in which case either loads of little cups, or less big cups are both the same result, the flow into the bowl (or the torque at the wheels) is still the same.
