3.08's - 3.45's, noticable difference?

[V85000i]

just wondering who has gone from 3.08 ratio to 3.45, and did you notice a decent improvement in feel of power and acceleration? does it pull alot harder? are you glad you done it?

[Wagon_Wheel]

Im also looking at doing this soon, any advice would be much appreciated.
Not sure whether i'd like to go to 3.7's or not, cause id still like to get a few k's out of a tank

Hey not exactly but 3.36 to 3.9 and with good results

[V85000i]

3.36-3.9 = .54 increase, =

3.08-3.45 = .37 increase, =

[weedo_86]

not much difference with the 3:45s im happy with them for now

Goin from 3.08 to 3.36 in my VH wasn't much of an increase, it was slightly noticable, same as when I went from 3.36 to 3.45, maybe slightly. And in PEAKN6 we went from 3.08 to 3.36, slight different.

So yeah, it should be slightly noticable....don't expect a big improvement.

put it this way if i were to magicaly clone my car, identical to what it is now, but fit 3.45's to the clone, how far ahead would the clone be, 1, 2, or more car lengths.

[immortality]

gotta be a couple of car lengths i'd say. unfortunatly my 3.45 gears came with an newly reco'd LSD (shoulda just fitted a minispool, it's about the same) and before i had a chance to test it i also fitted a new 2.5" zorst. before mods it was doing a 16 flat 1/4 mile. with those 3 mods it's dropped to a 15.2 still on stock 195/70/14's so as you can imagine even with the LSD traction is still a huge issue at the mo. i can definitly notice the difference with the acceleration

i had 3.45 gears in my diff in my auto VN clubby
made a good difference but now i want more

and btw that diff is for sale

I went from 3:08 - 3:45 - 3:37


The initial change was noticeable, and highly worth it for the cost. I then changed complete diffs and went with 3:73s, and still get pretty decent top end speed.


Also to note, i still get over 600k's to a tank with 3:73s, so don't be too worried about that weedo

[V85000i]

i do about 70kms of 100km/h open road driving 6 days a week,

Anyone know what rpm I would be doing at 100, going from 3.08 to 3.79?

The car is a 5litre 5 speed that does about 2000rpm in 5th.

Thanks alot.

^^^ Approx 2500rpm give or take.

Not sure if this has been posted before but attached a handy spreadsheet to calculate RPM etc.
