Ok how much kick in the pants would one expect from goin from 3.27 to a 3.45 diff ratio..
Before you ask 3.55 or 3.7 would be better but for $100 for the c/wheel & pinion , I cant really go past it can I.. Just had the bloody diff rebuilt about 2 weeks ago, man i cant believe it..
Thanx people.

Going from a 3.23/3.27 to 3.45 on its own isn't going to make a hell of a difference in itself as its only 5% lower gearing but it is going in the right direction. Its not any more difference than changing from 60 to 50 series profile tyres. In the higher gears you might just notice the difference and in an auto the initial pick up may feel slightly better.

The overall pickup will be a bit better and over the full 1/4 you might trim a few tenths of a second. for a $100 though I would do it for sure.

Well I felt a difference between 3.23 to 3.45... People will always throw figures at you but what matters is the pants in the seat feeling. There was a lot more of that in my humble opinion. However, I noticed even more of a difference between single spinner and LSD! :D

The difference is quite noticable IMO, much livelier, with what seems like better throttle response.

i changed from 3.27 to 3.45 to be honest with you i didnt notice much difference at all, although im not sure if its because i was excited that the clunks where gone or becasue i had lsd but yeah i didnt realise THAT much of a difference. maybe just a tad on take off. maybe in an auto you would notice it more.

OED666 · 08-23-2004, 01:27

well, i think there would be a difference... I went from 3.08 to 3.9... Huge difference... Rollin still has my 3.08 one wheel hero diff, and its a completely different car to drive as opposed to mine...

For $100 i dont think you can pass 3.45's...
