im trying to find the gear ratio in my diff. is there anything different when trying to find the ration with a open or posi unit? iv tried to find it using the open method and it says i have a 1.5 gear ratio. that dosnt make sense so i was wondering if anyone out there knew what that means. if i raise the back end and turn one wheel the other one turns oppisite direction. meaning i have an open diff. but when i do a burnout i get both to spin eavenly. i asked my friend who is the son of the guy who was head of the mustang racing team way back when and he is also stumped. anyone know out there??
