VE Maloo diff

[bothur]

Hi Guys,

I need some direction here in regards to my Maloo. Its the Ve LS2 A6 with all the usual mods, incl headers, cat back, Otr and a tune. It runs consistent 13.2 on standard 19's. I have now fitted a set of 20's and am considering a diff change. Standard ratio is 3.27 and am thinking of purchasing a complete diff assy as advertised in the back of the Street Commodores mag for $1550 in a 3.70 ratio. My question here is, has anyone done this before on the A6 maloo, was it a straight remove & replace & was there a noticable difference off the line and what am I likely to reduce the 13.2 by ?

thanks

check Holmart for complete diff price as well... I just bought one through them online , good price and easy to order.

Did the new one bolt straight in and what ratio didi you get ?

[IFN60]

Hi-Torque are $1750 fitted

I went 3.45 ( VE SS auto is 2.92 standard ) , it cost $1450 or there abouts, advertised as hardened ( shotpened like HSV ) gears. Yep it bolted straight in , they are holden surplus apparantly.

I have had 2.92, 3.7. 3.45 and 3.27 diffs on the VE A6.

I up graded from 2.92 to a 3.7 on my l98 with bolt ons and cam and it was a fun car to drive. I think it ran 12.2 from memory. I had a big cam at that stage and the cam did not make much power down low and the diff gears helped counter that.

I have had 3.45 and 3.27 on my 427 and 3.27 are by far the most street friendly due to the power and torque of this engine.

I think it will all depend on where you want to go power wise, the 3.7 diff on the A6 with 500rwhp would be smoke city.

[Sunny08]

Why not try a stall converter instead.

[Wonky]

I remember reading a thread on here about a year ago and in it someone posted they'd tried everything from 2.92 through to 3.7 in their VE A6 at the drags (maybe it was Sunny08???? :confused:) and best results were achieved with 3.27.

Changing centres is easy - an hour or so labour - straight swap.

[bothur]

Well at this stage I am not in a possition open the trans or motor and can change the diff assy at home. I would also like think that going to the 3.70 would be beneficial now that I have fitted 20"s. If at all possible with the diff changed to 3.70 I hope to drop 2-3 tenths of the quarter mile times that it currently does, what do you think ?

[Wonky]

etrocket has 3.7s in his A6 and seems very happy with them. (Check some of his threads.) I had a VE SSV A6 sedan with 2.92 diff and 260rwkw and at the LS1 Nats in 2008 could manage a best of 13.17 running stock SSV rear rims.

With the A6 ute and virtually identical power (261.3rwkw) but 3.45 diff we ran 12.83 at the 2010 Shoot.out running on 18s with semi-slicks, but 60 ft times were identical, so don't know that the semis helped. Read into that what you will...........

[bothur]

Thanks for that Wonky, that does give me some good confidence in going to 3.70 after your info. last run at Willowbank saw 3 runs at 13.3 with 2.1 @ 60ft and a 4th run at 13.3 with 1.5 at 60ft.

[Wonky]

Our best 60fts (Tuffie drove as I don't trust my reactions at close to 200kph) from memory were 2.02 each day.

[bothur]

Correct me if i'm wrong here, but I think with a simple diff change that will give me more bang for my bucks. Diff only @ $1750 versus cam/springs @ 3K.

[etrocket]

Thanks Wonky. 3.7s was the best mod I did. With cat back, gears, tune, air box and LPG managed 12.88 @ 109.5 all on 19" street tyres. Best 60" was 1.996 which is good for a ute. Haven't seen too many people get that low. Car had 250 at the wheels so yours should go better than mine

Thats bloody impressive, 12.88 with your mods and 250 at the wheels. Can you tell if you were in 4th gear across the finish line ?

[Sunny08]

with your 60foot at 2.1 did you have wheelspin or did you bog down?

[etrocket]

i think top of 4th over the line

[bothur]

No wheel spin evident !

[bothur]

Interesting, with mine in its current standard ratio I'm top of 3rd over the line.

Variances of 100ths of a second mainly due to track condition and the idiot driving , but consistently lower average time with the diff change.

[Sunny08]

I have started by stalling car with foot on brake and accelerator at same time. With the 3.7 I averaged in the 1.8's with wheelspin and drag radials for 12.2. (tune, exhaust, cam, otr)

With the 3.45 diff I was in the 1.6 range with wheel spin and drag radials (also had 3800 stall convertor for this) haven't run with 3.27 ratio but would assume I would be able to lower time again with less wheelspin with the taller first gear.

[bothur]

Sunny08, do you think I may be going in the wrong direction here with a diff change to the Ve Maloo. Should I look into some smaller rear wheels if at all available to clear the AP 4 spot brakes with ET radials ?
Bear in mind this is only a 257 RWKW Ls2

[Derek ve ss]

Mine is with stock stall, street tyres and auto in drive / normal shift.
The most I can get the engine to on the brakes is about 900-1000rpm hence the crap 60ft times. I think for reducting times on my car a hight stall would be a better investment than the diff change ( but I dont want a car that is drag oriented , I do track stuff as well ).

[Sunny08]

I think markone2 achieved a 1.7 sixty foot with ve maloo with 3.27 diff with stall convertor and stock tyres and ran in the 11.7. He had a pretty big cam and 5000 stall from memory.

I think a decent stall will get you better times. Unsure what wheel options you will have. I have the omega rear brakes on mine and can fit 16 inch rims on.

My advice after modding many cars is plan very carefully otherwise you will be changing mods you have already done.

If you do a decent cam and put in a stall you should run low 12's high 11's if it hooks up.

[etrocket]

just bare in mind your car is 99% DD. 3.7's might not be ideal for the track but for everyday driving is perfect. car gets going with little effort.

PS no ve (including hsvs) has ever beat me off the lights 0-80kms

[ADAM 26]

i bought a used 3.45 diff from another ls1 member for $250.00.

going from stock 2.92 to the 3.45 was a welcome change. easly the best value for money mod on the ute. i think with a 2500rmp converter mine would be sweet, but it would have a hard time hookin it up on the street.

also the change has made towing the boat easyer, it will pull it in 6th now, and not often change to 5th. before it needed to stay in 5th and would always be changin back to 4th to pull the load!

Probably a thread hijack, but this was closest thread that tapatalk revealed under a search.
Can anyone give a real world measured difference (eg 0-100kmh, etc.) difference that a change from 2.92 to 3.27 makes (on A6 VE's)?
