I think you're mixing some things up... think about what part you're replacing, and what effects what.

The steering rack is what determines how many turns you have lock to lock (and more specifically, the inner tie rods). If you disconnect the knuckle from the rack it will turn MUCH further than it does when attached to the rack.

The Perrin quick steer parts simply move the pivot point inwards on the knuckle. The result is that the knuckle (and consequently the wheel) steers more for a given input from the rack. The rack itself isn't changed in any way, just how the knuckle responds to input. You'll have a greater total steering angle with the Perrin kit since it doesn't effect the movement of the rack.

Now if you were to buy a rack with a faster ratio but same overall stroke then you would have the same total steering angle as stock but less turns lock to lock. With comparable ratios it would feel very similar to the Perrin solution (except the Perrin kit would have more total steering angle) but go about it in different ways.
