Anyone know a way to calculate a 0-60 time if a different differential ratio is installed? I understand there are many variables. I am looking for a equation where nothing changes except the gear ratio.

As an example. if the 0-60 time is 10 with a 3.00 differential ratio and nothing changes except changing the differential ratio to 4.00 what will be the new 0-60 time? And, is any change a constant such as if the 0-60 time was 10 and the ratio was changed from 3.00 to 3.50 would the same formula still be applicable?
