[Rick Parker]

My rack is 2 1/3 turns lock to lock. With all of the components from various OEM sources that are mixed and matched on these cars as they are built, many different suspension setups are arrived at. The distance from the an imaginary line through the upper & lower ball joints to the center of the steering tie rod end is the influencing factor in how much the wheel will move for a given input from the steering wheel along with a given rack ratio. Of course this assumes no interference from tires or other suspension/brake components. This dimension cannot be changed without changing suspension components (if different spindle is available) so we look for a rack a different ratio. Fewer turns lock to lock gives "quicker" steering but usually at the expense of more input effort, and can be a little sensative at speed. Check the driver's input on the steering of an F-1 or Cart car for an idea what "Quick" steering is.
