Is this an eighties thing or something, because I'm not getting it!

That's about it in a nutshell. Two wheels turning at the same speed around corners in the wet = sideways. It's much safer if the diff allows the wheels to turn at different speeds during cornering and if need be lock up for sideways action or straight line traction when needed.

My old man has a 9" full spool STRANGE diff. 3.5:1 in the mustang, ready to cope over 550hp with the new engine.

It was build by Taverna Bros and is capable and rated at 2500hp .
(never going to give it that much though!)

No worries driving in the wet, as it is never driven in the wet (wouldn’t do it anyway.)

Its used for the occasional wedding/formal/cruise, but mostly for Burnout comps, drag racing etc.

The only thing that gets annoying is the occasional chirp around sharp corners.

I wouldn’t do it too a daily driver as tire ware and noise issues would be a problem but for a fun car thats not driven every day i couldn’t recommend it more!

Having said that we will be running full spools in '08 and will be interested in the difference in track times.
cheers

I was told the same thing,and was worried when I fitted it,but it turned out to be the most predictable I have ever had the car,alot more so than the LSD,I only fitted it as I got very tired of burning out an LSD every 6 months,and as I drag race the car as well as circuit,and was told trutrac wouldnt be happy with 6000rpm dumps on slicks I had a full spool fitted when I had a strange centre built,I have found it to be just a rumour that the car will push straight on a corner,it is very much more predictable and easy to drive than an LSD for me..

Rev28K · 24-09-2007, 05:20 PM

I was thinking about one in my Datsun but others have got understeer with them when they have had them fitted. Add the fact that I may be out when the track is greasy and they become more and more of a liability. Good thing that the IRS Nissan R200 LSD can be built to take a lot of power (but not ridiculous amounts (>475kw)).

In an everyday car that is driven in all weather-conditions I don’t think they are a good idea at all

Spools are for Drag Cars, some Circuit Racers and Cheap Skate Nuffies who run them on the Street.

So they perform well enough for circuit racers but not street cars?

Yes, they do perform well enough for SOME dedicated Circuit Racers that run VERY sticky Tyres all round, like a V8 Super Car.

So unless you are running the same Tyres as them, I would stay away from a Spool.

But wouldn't soft compound sticky tyres exacerbate the problem especially with high horsepower?

But if you run them on the Front, and not just the rear, it will actually go around a Corner. I wouldn't say V8 Super Cars don't go round Corners well.

red_hotxr6 · 24-09-2007, 06:58 PM

Is there a way to tell if you have a mini spool or a welded diff?

i must be a cheap skate nuffy as i had one in my xb wagon for 5 years never had a problem or broke a axle or anything ppl say happen when you fit them as nugget said they are alot more predictable than a lsd cos the car will slide to the camber of the road.

and everyone saying lsd are great thats there opinion been in cars with lsds they can keep them or maybe its the excitement of not knowing if your car is gonna kick left or right i would prefer to know where mines going.

I'm not disputing that V8 S/C's handle well, quite the opposite which further proves the versitility of spools. They are however like any performnace component, there will always be a compromise.

Walkinshaw · 24-09-2007, 07:50 PM

spool + street = braindead. Its not a topic for debate. Just accept it as fact and move on.

Yes it is not very good to have in the car as it wears the inside tyre that your turning.
In the wet ... Yes be very careful or you will come unstuck.

The thing I find the most (having the spool in for the last 12 mths Nealy) is that if you forget about it then you will come unstuck really quick ...
Always remember that the car is boss and you take it easy every time and you will be ok .

as for racing .. I went from 2.9s = 60foot and 9.8s = 660foot with my stuffed lsd(basic single spin most times) to 2.0s= 60foot and 8.6s=660foot
So yes for the price of a spool you will pick up some time on the track.

2.9's to 2.0's because you had a spool? I ran 2.0's with a worn out 25 spline 2 pin lsd and cheap tyres in my old ea. im sorry , as if you are going to gain a second

EBFalcs · 24-09-2007, 08:04 PM

most ea's can't even spin a single wheeler, lol.

Another self-appointed expert, I can only offer my opinion based on experience. Your wisdom appears to be far more concrete than that.

I am talking about circuit racing.
Driving hard enough on the street to be able to step the car out,and use that predictability is insane,and nothing if not UNPREDICTABLE...

Just to clear up any doubt about my thoughts of a spool on the street...

don't bag the ea's. they are capable of beating any late 70's to 80's clevo[stock on stock]and if you don't believe me ask some of the guys that have owned them. they were pretty quick taxi's.

What? Are we comparing Auto's, Manuals? 3.3's, 3.9's vs 302 and 351?
Too many variables, eg 10,20 years of wear and tear...
And dont say the EA had a 'freak motor'
Sorry mate, but EA's suck as a stocker...

I've got a collection of those splines as paperweights from my misspent youth :-> They just twist right off the end of the axles altogether...

prydey · 25-09-2007, 09:24 AM

like i said earlier, i had one in my eb and it was a daily driver. rain, hail or shine it got driven and never came unstuck. i go around plenty of corners in my daily travels as well. the car is not stock and makes fairly decent power with 3.9 gears in the rear. my age does start with a 3 which may be the difference between staying on the black stuff and ending up hugging a pole but from my experience they don't do anything you don't tell it to. you just have to remain aware of it at all times and know its limitations.

Poetic Justice · 25-09-2007, 12:16 PM

For every day driving I wouldn't recommend one, but for a weekender sure why not. My car has one, but I don't drive it that often, and well, when you want to ark it up around a corner (on the track....) it certainly helps.

Though, I think with the power I've got running in a light car, an LSD would do it just as good. I think the difference between the LSD and the mini spool is that unless your LSD is fresh and tight, the mini spool is far more predictable and easier to control when you're giving the car stick. My expieriences with LSD tell me that it doesn't always do what you want to do (when you're a hoon.)

At least understand that some people when young want to be hoons - and if you weren't the same at say, 18-22 then perhaps you're not a real revhead. Minispool is only going to help you cater for that revhead nature, however it must come with a strong warning that you must at least experience what you're doing before you get confident with it.

mrniceguy · 25-09-2007, 04:09 PM

I had a spool on my old big block XY. Took it out and replaced it with a shimmed up LSD. The bloke who built it used to build centres for circuit racers which spent some of there time with the inside wheel of the road, so it was pretty tight but didnt do the annoying chirping thing through the local servo carpark. Will probably go LSD again for my Landau.

iv'e owned 2 of them, and an EBII.

jakkes · 25-09-2007, 06:00 PM

i had one in my xy for a quick fix until i had some more money for a rebuilt 9in
was running 25 spline 3.5-1 BW biggest problem with them is the under steer they give on the open road. tyres didn't wear as fast as people say. you could go around in circles all day and not break an axle. but was a 50/50% chance that you would break one on a standing start hard launch or burn-out i broke 3 doing this. not fun when your 2.5 hours away from home (was a funny night that one

)

i guarantee you that single spinners have claimed more cars then spools
