Diff gear for alloytech 6spd

[paulo vz]

does anyone no what a good choice for ratios is on a vz v6 6spd it seems to be too slugish off the line and does anyone no whos good to take your car to to get work done as ive onli just moved there from townsville i want to get it tuned and get an iduction put on any help would be great cheers

[06vzcalais]

umm, moved where from townsville, noone can help you if they dunno where you live

[paulo vz]

sorry mate just got home from work pretty tired umm goldcoast ill take it to brisbane if need be but yer dont no anywhere and dont want anyone dodgy working on it

hi torque performance at labrador did mine
then matt stocker at browns plains

[andyman]

i wouldnt go anymore than 3.27:1 for driveability,

i find getting 45km/h out of first gear @ 6700rpm get annoying, same as 95km/h in 2nd @ 6700rpm using 3.46's

if you dont like the take off, upgrade to a single mass flywheel and heavy duty clutch if you like to give it stick, otherwise even standard replacement with solid flywheel is a great improvement,

downside is gearbox chatter is a lil off putting at idle, anything over 1000rpm you dont here it unless you labor it hard under 1500rpm,

as it goes, if you want performace there is always a trade off

well i actually looking into a new clutch in the next couple of weeks as mine is pretty much fried the only single mass anyone can offer me is a exedy heavy duty for about 1650 for the clutch kit do you no if they are a good clutch ?? i defiently want a single mass because i dont want replace the whole clutch assembly every time i do a plate

arent they 3.45 manuals ??

[paulo vz]

im not sure mate im only new to this and havent been able to find a defient anserw on the net yet so yer so any help would be great

[paulo vz]

2.87?? is standard is that correct

[PaulSV6]

arent they 3.45 manuals ??

V8 Monaro's have 3.46

2.87?? is standard is that correct

Yes, VZ SV6 is 2.87 manual & auto.

Ive still got a 3.08 diff, waiting to go in.

[paulo vz]

oh rito mate you planning on putting it in anytime soon if so tell me how it goes

[VzVzVz]

I like mine just stock, i dont want to rev higher than i need to on the highway. just a waste of fuel.

plus, the alloytec is fine off the line for a v6, why change it?

[PaulSV6]

oh rito mate you planning on putting it in anytime soon if so tell me how it goes

Lol, define that!. Ive been wanting to install it since may last year. I just haven't had the time.

Also, with a mod like that, you need to acknoledge the rear axles, that is where the most of the vehicle's torque is applied. If you go reducing ratios, you put even more torsional strain on the axles.

[paulo vz]

well pretty much im planning on putting 10 to 12 into the car i need a clutch so that will cost me about 2500 and just want to get it goin quick enough to pull away from most na sixes without chrgin it so that just why im asking these questions to try and figure out whats worth doing etc

[Vt_vic]

the best way to pull away from the other 6's is to charge it or 3.9 ratios in the diff.2.87 would be terrible for takeoff i hate the 3.08 but my mate vz ssz has 3.7 in it dunno why they went to 2.87?

where did u come up with this.. the new diff gears wont put that much strain on the axles..

As for the clutch have you tried pricing the extreme clutch? It worked well for me, and the gearbox chatter isnt that bad if installed properly

ive got the daikin/exedy heavy duty in mine, works great, nice and streetable, better feel than the standard clutch, also comes with a new slave cylinder and spacers and bolts etc

would be worried at all, those cv shaft could take abuse with a v8 280rwkw car and not bust, they sort of start to fail around the 350rwkw up

3.9's would be all well and good if the aisin box didnt almost have a 4.5:1 gear ratio for first gear, using 3.9's would make first gear unusable,
