Final drive ratio
Hi guys
I seem to be suffering brain freeze at the mo.
Can someone put me in the right direction , I am considering changing my diff ( currently run a 3.6)
But cannot for the life of me remember what way to go , I got good pace on my car but because its an ex race engine it was built for short circuit
racing and has a rev limit exceeding 8000 rpm and does not come on cam until around 4000 rpm .
What I am looking to achieve is better acceleration , so by changing the diff to a 3.9 or 4.1 I should get this ????
I am sure there is someone out there that knows .
Also does anyone know of such a diff hidden in the back of there man cave going cheep but it must be a push in shaft and a 7.1/2 " diff.
Thanks in advance
PERSEVERANCE is the word of the week. Stick with it the results are SWEET.

You are correct, you need to go higher Final drive to increase acceration/reduce top speed.

Careful with terminology normally a higher final drive is lower numerical ratio.
It is usually less confusing to refer to long or short ratios-
Long final drive = low numerical ratio for" higher" top speed. For example 3.31:1
Short final drive = high numerical ratio "lower gearing" for better acceleration. For example4.21:1
