How to increase addTorque spin speed

I add torque to my ball but torque speed doesn’t increase.
I have tried to increase max angular velocity from edit → project settings → physic, but it doesn’t work

This my script

    void FixedUpdate()
    {   
        if (Input.GetMouseButtonDown(0))
        {
            this.rigidbody.AddForceAtPosition(Vector3.right * 1000, transform.position);
            this.rigidbody.AddTorque(Vector3.left * 20000);
        }
    }

You would like to adjust your torque parameter in the inspector while you Play the game,
and to make those things easier add this parameters.

	public float angDrag;
	public float spinForce;
	public float maxAngVel;

	void FixedUpdate()
    {   
        rigidbody.angularDrag = angDrag;
		rigidbody.maxAngularVelocity = maxAngVel;
		rigidbody.AddTorque(0,10 * spinForce,0);
		
		if (Input.GetMouseButtonDown(0))
        {
            this.rigidbody.AddForceAtPosition(Vector3.right * 1000, transform.position);
            //this.rigidbody.AddTorque(Vector3.left * 20000);
        }
    }

Play the game and adjust angDrag, spinForce, maxAngVel in the inspector
