Difference between a full spoll and a mini spool if any??

[w3bstr]

Just wondering what the difference is between a full spool and a mini spool if any...

[Morton]

If you get a full spool, you replace the whole carrier. A mini spool only involves replacing the spider gears inside the carrier with something that locks up the differential motion. Mini spools can, and will break. Full spools on the other hand, will take a lot of punishment

If you stick a mini spool in there and it blows while you're cutting loops, there's a good chance it'll take your gears, carrier, and even axles along with it

If you want to be cheap, weld up a stocko single pegger. If you do it properly, and lay about a kilo of weld in there, it'll be stronger than a mini

lol yeah just getting a full spool temporarily, holding on to it for a mate with limited garage space lol... Dunno how long i will have it or anything but yeah was just curious. Its also only for a 6 lol. The guy i am getting it off has a 308 fully worked vh, hasnt fkd up on him yet so i dont think im gonna do any harm to it.

Thanks

i think you need to take the words minispool, and weld, and swap them around. i never hear of spools breaking, but always hearing about welds breaking and taking out the diff with it?

That's because nobody puts enough weld in there You need to ideally pour a bucket of molten metal into your carrier

minis probably aren't that bad for daily street use. I'm just assuming this bloke wants to cut 5000rpm loops around his local estate. I mean, you live in Hillside, right webstr?

+1, never known a spool to break.

[VN_Luke]

+1 for never heard of a spool breaking either.

as morton said already - a full spool is basically just a whole carrier, consisting of a solid tube that you insert axles into, and a ring for the ring gear to bolt onto. It replaces your whole diff centre.

a mini spool is simply a block of steel with axle splines and holes through it, and it replaces the whole inner parts of your current diff centre (i.e. it does away with all the spider and side gears)

welding is a cheap way out - but it's hard to get 100% right. you need to clean the whole thing out properly and then get HEAPS of heat into it (need a decent size welder!) in order to get any penetration. Then you have to be careful to not weld too much to stop the axles going in (or out lol), and so that everything still operates as it should! - i guess you'd also want to be careful about warping anything with the excessive heat.

advantages of a full spool over a mini include:

- much lighter
- less parts, and therefore less likely to break stuff
- it's a hollow tube - so if you break an axle at the splines, you can just smash it out with a broom stick or something from the other side. (whereas with a mini spool, you have a pin going through the middle that stops you from doing this)

and that's about it

here's a pic of a full spool and a mini spool

minispool installed inside the original diff center:



if you got the cash... go for a full spool.
if you don't have the cash for that, go for a mini spool.

if you're adventerous or don't have the cash for either of the above - crack out the welder and beer

Better pics of full and mini

[Morton]

Does anyone sell stronger aftermarket center pins for minispools? I somehow see them as being a bit of a weak point in the whole operation.

[cpbait]

whats the average price for a full spool and mini spool installed,
are they ok for day to day driving or more suited to the drag strips?

[Morton]

day to day should be fine, so long as you don't live at the end of a tight series of wet high-speed S-Bends

Oh, and don't park anywhere near the fuzz They'll be all over you like a rash.

But I know quite a few people who run spools in dailys and have no issues.

I know a mini spool is worth around $50-$80 by itself. I can only imagine it would cost around $250 to have it installed.

[stocky]

or just read the thread that luke posted

[VN_Luke]

I dunno man - there's 4 pins and they sit in a solid chunk of steel, not too much to go wrong. I think you'd break axles and crownwheel/pinion teeth before you break the pins (not the case in a single spinner though - cause there's crazy heat generated etc which affects the performance of the pins in a big way!)

as morton said, 250 for a mini?
and 500-600 for a full?

you CAN drive them day to day, if you want - but you'll know it's there, and it's well and truly illegal.

fact is that they're best suited to burnouts, drifting and drags - where 50/50 power distribution is key.

i guess my theories are:

1) if you have to ask, you won't like it.
2) if you haven't tried an LSD yet - best to try that first
3) if you have tried an LSD and are dissapointed with it singling right away - spools are for you.

[Morton]

I reverse parallel parked the VQ today on a bit of a hill with the manual steering and the manual box. It wasn't too bad at all! Makes me think I could manage with a spool on top of that

If my current LSD wasn't tight, and if I didn't have another near-new LSD sitting in the garage, I'd almost consider a minispool ^_^

[sway9]

hey can i just ask are these spools just the same as say Detroit Spinners? the things that make both rear wheels spin?

[Morton]

Rainbows. Rainbows and pixies

The simplest way to explain it, is that a Detroit Locker works like a ratchet. It will let your wheels turn faster than the applied drive, but not slower. It uses clutches with teeth, and a cam thing in the middle. When you coast around a corner, the teeth with a super special negative angle on them, are allowed to slide up the cam like a ramp, and disengage This unlocks the thing. Stuff. And magic happens.

So, if you are driving around a corner with your foot off the gas or very light throttle, the inside tire will be locked to the ring gear and pulled along by the engine, while the outside tire will be free to unlock and travel faster. As fast as it needs to.

But if you then mash it, and apply more force to the point where the rotation of the outside tyre does not exceed the applied force, you are then locked in on the ratchet on both wheels, and it's locked, giving you a twin spinner

tl;dr version:

On throttle: locked up
Off throttle or not much: unlocked

[sway9]

thank you very much that makes perfect sense now. (im not being sarcastic im glad someone put it in tose terms not dumbing it down because im "too young and inexperienced to understand") thanks again mate

[Morton]

No worries mate It took me ages to grasp the concept of a detroit locker at first. They're a tricky little diff. But people who use them say they'd never drive anything else again

Oh, and don't park anywhere near the fuzz They'll be all over you like a rash.

hahaha that happened to me, i parked my car a the servo to go get a drink (parking spot not infront of the pumps) and was a tight turn... I come out to see there is like 5 vicpol vehicles, 3-4-5 point turn and got the hell out of there haha

mini spools are more then enough, and you wont break one no matter how many rpm your doing only time you would break one is if your car was an insane powerhouse.

so cheapass (like me) = mini spool
powerful car and runs 8's = full spool

haha gold!

I've been pulled up 3 times with a spool in my vp. (go sleeper!), and once with a spool in the VN

1) roadside stop, breatho, quick chat, and pull away around another car (little chatter but nothing noticable)

2) I'd had a few drinks (was passanger) and my mate was driving my car to 'a congregation of people in an industrial estate' around the corner for a quick look-see after we heard heaps of noise. The police had the same idea as us, and blocked off the exits not long after they had a look-see.

Thorough roadworthy inspection, but got let go and told to leave - we did a 10? point turn to get out from between two cars, around a cop car, and drive off. - the nice man who'd just let us off was initially like "there's plenty of room! just drive out on hard lock".... his face changed as we chattered away around his car (while I was drunkenly attempting to mask the sound by coughing really loud out the window)

3) got pulled up on a Friday night going to drop some friends off - cop asked if my car always sounded this sh!t, or if it was just cold. (it was supercharged) - I said it's just cold and a noisy power steer pump that I need to fix. - asked for license, which I'd left at home around the block, so he told me to turn around and go get it..... 5 point turn where a simple U turn probably could have worked (lol) - but he was none the wiser.

4) got pulled up in the VN - pulled over, had a chat, drove away, no problem!

I found the softer the tyres, the less noticable it is. If you're good with the throttle then I reckon you could probably do a U turn right in front of the fuzz on some highway max's and they wouldn't even notice.... do the same thing on RE92's and you'll be squeeking/chattering all the way to vicroads

[padrickz88]

LMFAOOOOO @ you trying to cover it by coughing hahaha

i need to burn out my current tyre's, there to hard and always chirp, so ill fix them MWAHAHAHA!

another way is run 2 different tyre's.. makes hiding a spool so much easier because one will grip and 1 will slip easy, depends on the tyre's but..

what i find funny is how people say reverse parking is shit with a spool, i find it pretty easy :S

lol... This became a decent thread hahahaha... LOL at vn_luke hahaha.

*runs and ducks*

no comment..... well, it does have 3.5:1 diff gears... instead of my stock single pegger 3.08:1...

[Morton]

no comment.....

None needed, mate. None needed.
