Hi everybody.
This is my first time posting after browsing this site for over year and let me say, this site rules.
My first question is, can anybody confirm me that a ratio of, let say 3.90:1, means that the pinion flange or driveshaft turns 1 time for 3.9 tire revolutions or it is the other way around? The logic for me would be that you would want less driveshaft revolutions for more tire revolutions.
