what should i do with my Diff???

[PaRaDoX]

hey, ive currently got 3.08s with a open diff (stocker)

with the turbo going in soon i cant just leave it stock...

i was considering a lokka but now im thinking spool

im looking for strictly a locked diff, ive heard LSD's are weak because of their clutch

what are prices/idea's that i can do...

im looking for 3.45s
VLs have 3.45s in their diff dont they??

i think the vl turbo diff was 3.45

[AirStrike]

i think the vl turbo diff was 3.45

All 6cyl VL's have 3.45 regardless of N/A or Turbo. The V8 VL's are 3.08:1
Personally mate I would go abit more, I had 3.45 in my Calais and its harly noticable. Get some 3.7's from a R31.

My LSD is stuffed in the VN 5L sedan but is still better than the single spinner in the wagon.

depends what you want to use it for!

if you want a diff to get you some traction taking off, an occasional burnout in a striaght line, an LSD will be sweet. get a new set of cones when you first put it in and it'll last you ages.. (20-40,000km - depends how often you do burnouts ) a tight lsd setup with new cones will cost you around $4-550, if you fit the center yourself.

if you plan on doing a bit of circle work and being generally a bit silly, a spool is a cheap easy solution, however, it's a solution that there's a chance you might regret... it's also illegal (for a good reason i guess), and can draw attention that you definately will NOT want with a home turboed vn cost of a spool is about $150 if you fit it yourself (inc. diff oil + gasket)

I don't know anyone that's tried the 'lokka' diff center yet... I'm very keen on putting one in my car, as it seems to be a good compromise between constant double-wheeeler-action-super-fun-happy-time, and legalness! I'm keen to see how the lock-unlock actually feels while driving.. these centers cost $599 + freight... add some diff oil and a gasket you're looking at around $700


you could also go a kaaz mechanical LSD center, they're over the $1k mark, and while I've heard good things about them - I don't know enough about them to recommend/not-recommend.

as said above, all 6cyl vl's had 3.45's that will fit into your diff.

with gears you have to figure out what size converter you're going to run, whether you're going to run a lock-up converter, what revs your turbo will be spooling at and where your torque band will be.. from there you can figure out gearing so that when you shift gears it will land you in a sweet spot, while keeping in mind that you don't want to be doign crazy revs down the freeway

Hope that helps!

[walesy]

spool it! you'll never look back!

[Charg'd]

i vote spool, just be careful

[azkwazere]

dont go spool, spend the money and get a detroit locker..

aZk.

[defa]

i woudn't say to go with a detroit locker. from what i have been told ya have to learn how to drive with them. i think back in the bathurst days in the 70's people had trouble with them not unlocking before they would enter a corner. i don't know much about them and can hardly remember what i was told about them. i just remember they are suppose to be a littl tricky.

[AirStrike]

I personally having driven one, would never recommend a Detroit or similar locker, they are simply out dated technology. The trouble with a Detroit locker is they lock and unlock sometimes at inappropriate times. With a DL it is locked during all normal driving conditions and they unlock during conering, which here inlies the problem. If you enter a corner quickly it is possible for it to be locked, get the ass end out then unlock lossing power transfer to one wheel making the car straighten up, THEN causing the rear to lock again.
I don't know how it would be in something with less power (I drove this in my uncles BBC HQ, which is now a full spool) but personally I would go for either a LSD or mini spool.

[walesy]

spool for reliability... after a while an lsd can be pretty un-reliable and start doin one peggers and if it does it at the wrong time it will throw ya...if you have a spool get good bushes to keep the back end tight

[PaRaDoX]

heh ok, i thought R31s had 3.9s? not 3.7s

i want this car to be a rocket to 100km/h but still beable to cruize at 100-110km/h (fastest legal speeds in victoria)

im planning on a 2000-2300rpm stall converter nothing too harsh so ive still got alot of usable Revs, this engines not going to rev out to like 7-8, limiter will be set at 6000rpm,

im leaning towards a LSD, with 3.45s / 3.7s
i dont want anything to really compromise the drivability of the car such as a spool + the guy i brought my turbo off snapped his axel and rolled his vn, (is 13 on the S/C list, 13 flat with nitrous N/A)

how much do they usually go for second hand???

[10000_fists]

i was at diff joint on the weekend... my mate has a VU with lsd but only spins single unless its wet, he asked and the guy reckong aroun $800-900 including labour to repair it, but he said it could be good for 5,000k's or it could be good for 50,000 depends on how you drive...

I had a spool in my HJ for a while, my best mate had a spooled vn for 7-8 months and i got a spool in my vp 3 days ago, i would recomend them. all cars were stock or low power 100 rwkw max.

If ya put it on with the turbo i'd be looking at getting billet axels. sunshine diffs said it would cost me $600 for them installed. 3.45 gears would've cost $350 installed and a mini spool from him is $130 + instalation if needed, mine was $270 installed with a new center.

My mate spent 8 hours spooling his vn the guy at the diff center said it'd take him 2 1/2 hours max.

[PaRaDoX]

i think i need to drive a spool'd car to feel what its like

[10000_fists]

when driving normaly round corners and round abouts, you'll feel vibration/bumping in the arse end... depending on how sharp and fast you take the corner, also makes a chirp/squeel or scrubbing noise dependeing on tyre and road conditions.

To do a u turn you have to turn into someone's drive way and reverse out, even at a normal sized T intersection you have to do a 3point turn.

But the donuts you throw are well worth it, takes a small amount of practice and you can just pivot off the front wheels, the marks look insane and when i whipps around you can really feel the g's pulling you to the seat... this is in a standard VP.

I agree with this. Even my heavy VT used to flick around like a dog chasing its tail.

[PaRaDoX]

yeah, but cmon i already get reemed by the cops in certian area's round my area the cops know me personally and dont bother me, dont even look at me twice, yet i go somewhere like camberwell and cant make it 50 meters without getting pulled over twice.. dont really want a spool

[walesy]

i never had problems with my turning circle with my spooled car... 8 hours... was he playin with himself??? 3.5 max! if your vibrating that bad replace your bushes... mine got really bad skips on tight turns so i replaced the shot rubber bushes for good ones and you dont feel a thing... just hear the chirp

[walesy]

oh yeh billet axel would be good but standard ones usually lasted me bout 6 months... and i always gave them a workout! and you can pick up an axel from the wreckes for $40-$50 so its not that expensive... spools range from $90 to $120 depending on if the sales guy thinks your stupid

I think that diff joint is a rip. My LSD diff cost a grand to be rebuilt (acid washed, lsd tightened, shimmed, new cones, new bushes, the lot) AND with brand new 3.89 diff gears. SA Race Trans and Diff quoted me $1250 all up so they werent much different and the diff gears alone are around the $550 mark, so just for a complete rebuild I wouldnt be paying much more than $500.

[VRV666]

I have a mini spool in my race car and to be honest I dont think id like it on the street, for instance a rainy day. Without fail, everytime I spin the tyres she steps out, slicks and all. They definately guarentee an awsome burnout, the g-forces were mentioned above. But if this car is your daily driver and you dont want constant axle probs, I would go an lsd. If treated right itll last long enought and still give you the occasional bit of fun.
Also with a spool, you just cant hide the fact that its there, chirping around corners etc. But they are fun.

[walesy]

they hide well with bald tyres can hardly hear a thing

Para - Diff gears are as follows.
R31 Auto - 3.7
R31 Manual - 3.9
Pintara Auto - 3.9
Pintara Manual - 4.11
As for axles snapping.........it takes alot of power and punishment to snap a 28 spline axle.

pintara ones are round the wrong way... just so u know

Detroit Lockers are bad mmmk. They have a tendancy to lock and unlock constantly around corners espescislly if you drive hard. The inside wheel is the one with the drive and if it starts to spin then when it catches up to the outer wheel the diff locks up and you usually end up facing the way you came.

Spools are bad too mmmk. They are murder in the wet, with power to the ground you tend to go sideways and if you are cornering normally then it will try and keep you going straight. In the dry they aren't as bad because you have more grip on your front wheels. And as said above, the chirpy tyres give it away. Also they can snap axles if you don't billet them.

LSD would be my choice as well, they give you the best of both worlds, just make sure you replace the cones and oil when you put it in and it should be good for a party.

Each type of diff has a specific application. If it is a true locked effect you are after while still retaining drivability, spend the money on an air locker. The only downside is you need to be stationary to lock and unlock it.
