We do not play much with torque curves.  From most of the real car data
sheets that I have seen, however, the torque tends to be more or less
flat after a threshold rpm and then drops off relatively fast after the
maximum hp rpm.  In general the curves are not very carefully designed.
Most of the time we tried to match the curves' maximum hp and sometimes
torque values to those of the corresponding real vehicles, but the
overall _shape_ of the curve is probably not very realistic.

As for the placement of the redline, that has much to do with cooling -
I'd expect the torque to drop much faster after the redline though, than
it does in these two examples.

I am not sure that 'most' have turbos assigned.  Certainly some.  I
don't really know which cars have a turbo in reality.  In any case,
currently turbo is just a sound effect.
