Hi everyone,
Kinda embarassed to post this up but i'm tired of cracking my head over this. I don't understand how rear differential ratios work and their effects on a car's performance and fuel economy. I also don't get what's the difference between a limited slip diff and an open diff.
Have been googling this for awhile with no meaningful clarity...there are plenty of explanations as to how a rear differential functions but no useful articles on the effects.
I have figured out that the when you use the word "higher" to describe a differential ratio, you mean that numerically, the ratio is lower. I.e. if the baseline is 4.1, a higher ratio would be 3.64 and a lower ratio would be 4.44.
Furthermore, a differential ratio of 4.1 means the car's long shaft spins 4.1 times (input force) which causes the rear tyres to spin once.
That is the limit of my understanding. Would be most obliged if someone could shed some light on this matter definitively. Thank you.
rgds,
Roberto
