#pragma strict

var rotationSpeed = 8000;
 
 
function Update () 
{
  var rotation : float = Input.GetAxis ("Horizontal");
  rotation *= Time.deltaTime;
 rigidbody.AddRelativeTorque (Vector3.back * rotation);
  }

You are not using your rotationSpeed at all. You are only using Time.deltaTime which is a really low value (around 0.02). Multiply in your rotationSpeed and you should see a major difference.

rotation *= Time.deltaTime * rotationSpeed;
