I had 3/4 turn lock to lock with an 3.9"/turn Appleton rack and 5" steering arms. I've also run a 4.5" Sweet rack that was noticeably quicker. Pinion sizes were approximately 1.2" dia and 1.4" dia. These were on dirt late models. A standard road race rack is 2.0"/turn while an autocross rack might be 3.14"/turn. Easy-peazy...
