The 15 to 1 (3 turns lock to lock) number came from Flaming River, who made the rack. The stock MII manual rack is listed as 20 to 1 (4 turns lock to lock). The factory Fox body power rack is 12.5 to 1 (2.5 turns lock to lock, I think). I think the stock MII power rack is the same. Again, these numbers came from Flaming River.

If I'm not mistaken and I could be, gutting the 12.5 to 1 Fox body power rack and running as a manual was done on some Factory Five Cobra's many years ago, but the downside was high steering effort.
