But it does contribute to instantaneous torque.

As long as it's measured at a steady state.  I don't know about you, 
but I rarely drive at a steady state... <g>

For some values of torque.  Yes, it doesn't add to the numbers as 
typically published, but it can contribute to the fun, at the cost of 
smoothness vs. rapid engine speed changes.  Which is, of course, why 
there are different sizes.

In "simple" terms, torque is a force, and horsepower is how fast that 
force can be applied.
