Yeah I could have done with one about 4 years ago when I had the same thoughts as Taza - only thing is that I've not used auto cad or a program of the like that would have helped immensely!

When I was doing work experience at a machining place I asked the boss what he thought an auto locker like the PowerTrax (showed him one of my brothers Toyota ones) would cost to machine a prototype of. Assuming there would be no designing, he reckoned around $1000 for just the machining. That is using the right high carbon steel, heat treating it properly and cutting the splines and all.

Cost on bulk only got pretty decent when getting up to the 100's.

Wow, now thats abit. From what ive designed the customer would use the existing spider and ring gears. But if we test it and they break then they will have to be made up too. This won't be an issue as I have already roughly designed them in CAD.

Interesting... I like the concept behind this. 4 or 6 spider gears in total? You have 2 to each axle then either 2 or 4 in the middle, of course, 4 is going to be stronger in general as there are more contact points one the gear face to spread the load.

And what Phiz suggested is about what I would have expected for production ONLY - then there's the shipping and your cut on top of this. This is why I sent you that PM about producing the product so that others can't steal your hard work and ultimately $$$ from you (in production and profits).

Hey guys, well looks like my Hard Drive may not be recoverable. I got half way through re-programming the firmware when the cable busted. I have ordered another 2 cables but since I wasn't able to spin down the drive before the cable broke it might of just turned it into a brick.
I will wait and see if I can do it when the next two cables arrive but if not I have to start from a fair way back :rolleyes:

Really... Who? Why?

PM me about it.

The only reason I can think people don't want it too happen is due to someone or some company loosing money.
Well if they think they can hack my computer they can give it their best shot. Just putting that out there.

LOL, ever since people have taken the suby offroad, people have tried to make lockers...., but since they are virtually impossible to get means that most failed:(

mmm, probably the spirit of your old gearbox... couldn't bare to see more pain and destruction to its own kind :P

seriously, is there a chance this could push the old EA gearboxes too far, especially if they are hooked up to an EJ20/22/25?

and fingures crossed you do get it back taza!

If/when the prototype is ready we are probably going to destroy the gearbox and diff in the poor Subie. But as you guys have said we don't know till we try :mrgreen:

Thanks, yeah I hope I do get it back. There is a good chance the gearboxes and/or diffs plus CV's could break, especially since the old EA gearboxes were only designed to deal with ~60Kw of power. Plus I don't think Subaru intended that we would be doing the same kind of offroading as the big 4x4's. haha

But if you had the old 1.8 with original gearbox and a rear locker then it wouldn't have enough power to actually climb a hill. You would probably end up burning out your clutch.

I'm hoping it all comes good mate, I'm seriously keen to see this one through - just that I'm not a part of it like I wanted to be when I started talking about it, you've got some skills that I don't!

Sounds like it. I'm sure the subi gods will embrace it once they're out there ;)

I don't know about this Guyph. I think that there's been a lot of people talking about it and companies who say it can be done but make the price so high they guarantee that they get a profit out of it or that they nail it on the head with such a big ask ($$$$s)

I think you could push a worn EA box too far on the road. The idea of the locker is to make offroading smoother when the going gets tough or the traction becomes too slippery on one wheel. This locker should put less strain on the drive train than a welded diff will, simply because YOU get to SELECT when the locker is locked. If you're smart you'll pick your times carefully to prolong the life of your drivetrain.
I really think there are people out there that hear "Locker" and think "hardcore" but then forget about those who are running the old EA gearboxes with a welded ("CIG" locker) rear diff - it's the same thing except that the welded diff is always locked when the second shaft is put in.
The other thing to look at is that IF you were using the EA PT4wd gearbox the only reason why you'd shell out for a manul locker is so that you have the convenience of flicking a switch rather than stopping, jacking a wheel and installing the second shaft to lock the rear with the welded diff.

I have my doubts about this as posted above.

I'm hoping the weakest link will be either the CVs or the diff out put stub axles - which again wouldn't be any different to the welded rear diff.

And again as I've said - you wouldn't be running the rear locker ALL THE TIME when offroad, only when you need it. The biggest advantage to this locker will be the ability to run the AWD gearbox on the black top with an open rear diff and then offroad with a locked rear diff when you need it.

Dont ya hate all the problems with computers. Im sure its a conspiracy to make us keep buying new ones!

How bout a limited slip diff? Im guessing not as good as a locker but would be heaps better than a single spinner & im sure not hard to find
