removing rigidbody velocity cap

Why is it that you can add incredible amounts of Force to a body (rigidbody.AddForce)
but not of Torque. it seems that when you do

rigidbody.AddTorque(Vector3.up * x);

whether x is 100 or 10000000000000 it produces a rotation with the same speed, as if there’s a value you can’t get higher than.
And this value, I find, is pretty low-placed.
How to disable it? or increase it?

Change the value of rigidbody.maxAngularVelocity.
