Do diffs make differences

Allrighty then.
I got the EB6 pot with cam, exhaust, computer. Making 127rw/kw and 450NM of torque. Now its got a 3.23 diff in it and it doesn't launch off the line like i would like. Would puttin a higher ratio in like a 3.8 or something around this ratio help or not. Also any idea what the rpm at 100k would be, its a auto as well.
Cheers for any help.

Re: Do diffs make differences

id go 3.7's you will have the edge over the xr6 boys, without reving to much up high.....
i would convert to manual 2 with 3.7's you pik gears, and actually have to slip the clutch to ensure good hard launch... other wise wheel spin comes into play.....
revs beetween 2400-2700 at 100 kmph not sure as i have no taco,

Re: Do diffs make differences

Thats alot of torque

A higher gear ratio will always help take off, but hinder top end..

Re: Do diffs make differences

nope i dont think 3.7's hinder top ennd at all, WHO HAS HIT REV LIMITER IN 4th before in an auto......... if you can hit limiter 5750 in 5th with 3.7's and 205/65 tires its a top speed over 240/250 kmph.......

Re: Do diffs make differences

with an auto... it'll have u sitting on about 2200-2250rpm @ 100km/h with 3.7 diff gears.
going from 3.23 i'd deffinately stretch to either 3.7 or 3.9
If its an auto, i'd say 3.9's
if u plan to go manual, 3.7's

it does make quite a bit of a difference :D

Re: Do diffs make differences

2200rpm w/ 3.7s sounds pretty reasonable. What would 3.9s jack it up to on say 110km/h?
