Help anyone?

A spool or mini spool is fine for the drags, but not an everyday proposition.

stiddy · 25-06-2007, 07:09 PM

I wouldnt do it.
A spool on the street is a silly move, and lethal in the wet.

Plus, I think the EL diff is Different to the AU diff?

a spooled diff is illegal for road use and would be a pig to drive it would skip around corners a spool is only really good for strip use aqs it is a straight line. The 411 gears would give good acceleration but you would need to put a different centre in either a single spinner or better still an LSD also you would need to use your old housing and axles as the AU has a different offset

AUI99 · 25-06-2007, 07:14 PM

I've got a single spinner atm...Would the 4.11 gears consume more petrol?

stiddy · 25-06-2007, 07:16 PM

On highway yes, cause you'd be crusing at a higher RPM.
Around town probably not.

Yes - your car will be reving approx 30% higher for the same speed.

AUI99 · 25-06-2007, 07:19 PM

So the verdict is no?

stiddy · 25-06-2007, 07:21 PM

lol yes, dont do it. Well atleast not the spool part.

the 4.11's are upto you, its got its pros and cons like most things.. maybe get an LSD with 3.9's instead.

FGII-XR6 · 25-06-2007, 07:23 PM

your choice really but the only thing you'll be able to use is the gears (take this into account when considering price) you will use more fuel but the car will go harder off the line

I'd love for the car to go harder off the mark lol...But hmmmm i might just get a normal diff...Or mine recoed!

It's a good price for a good setup!

Having said that, I absolutely hate locked diffs in street cars. Having owned one for a short while they are absolutely horrid things to drive. They're a laugh for about the first 5 minutes, and then the rest of the time you're car is a plough understeering, snap oversteering pig of a thing which will destroy rear tyres, destroy your bushes, snap suspension arms and generally turn your car into a P.O.S.

I snapped the arms clean off the diff in mine simply trying to do a very wide u turn. I'll say it again, P.O.S!

Can you tell I hate locked diffs?

I get ur drift lol!!!! I'll go a normal diff then!

FGII-XR6 · 25-06-2007, 09:37 PM

what I did in mine was put in an XR6 non IRS diff that gives you 3.45 gears and LSD launches better and is not over the top you need to replace your speedo gear with a grey one

OED666 · 25-06-2007, 09:42 PM

get a lock-rite centre for your diff. they rule. lsd's are ghey, (i am talking from experience).

I had a 4.11 spooled diff in my EA. The 4.11s do somany turns to 1 that they dont skip that much at all compared to a spooled 3.23 that I had in the same car. Fuel consumption increased as much as the leterage per 100km that you normaly get around town, the highway leterage became the same. So for me I was getting 400km to a tank with an engine producing 215kw, with the same engine and standard 2.92 gears I would get 550 odd km to a tank.

i guess your missing the main point it is not legal to have a spooled diff on the road. they are dangerous for street driving and damage the roads when they skip and bounce around corners. a diff (they are called a differential because they allow the wheels to turn at different speeds) is intended to allow a car to corner. Install a spool and it is no longer a diffential but a straight axle great for a drag strip but useless for anything else

I was just pointing out that with 4.11's they dont skip much, realy they only do it if you do a tight u turn. I used this center for 2 years and about 40000km's and never had an issue with it or the police. Yes they might be illegal but so are most modifications we do to owe cars, you just have to make a decision which mods you want to risk the police finding out about.

Out of curiosity OED, what's a setup like that worth?

some mods should stay on the track / strip this is like puting slicks on a road car it's a non road mod and saftey dictates it should stay there even circuit racers wouldn't use a spool they are for straight line use

well if you already have an open centre, you just buy the lock-rite from 4wd systems for $610. you can fit it yourself if your reasonibly capable with tools.

lock-rite FTW!!!

no more one wheelers. they also behave extremely well behind autos.

Are they like an air locker where you manually select it to lock, and then deselect when you're done?

OED666 · 26-06-2007, 09:17 AM

they cant be turned off so to speak. it locks under load, either accelerating or de-accelerating.

eg. if your pulling out into a T intersection, if you accelerate in a straight line, its locked, but back off the juice, turn the wheel and roll around its not locked. then back on the juice its locked.

but if your parking slowly and you need to accelerate lighty it will lock.

Rollin has one. before he converted his car to a manual the other week, his car behaved so good with the auto and a lock-rite. you wouldnt know it had one.

Hmmm, so a bit like a less savage detroit locker then?

OED666 · 26-06-2007, 10:15 AM

pretty much... and much cheaper.

Mark351 · 26-06-2007, 12:01 PM

Behaved when it was auto, now that it's manual?

its still pretty good, way better than a mini-spool. it was just really strange driving it when it was an auto. you just wouldnt know it had a lock-rite.
