VauxSport - Vauxhall advice and chat forum

[chip]

Not sure if anyone on here is still after one, but following on from my thread from last year:

http://www.vauxhall-sport-forum.com/phpBB2/uprated-transfer-boxes-from-qrew-in-sweden-t3749.html


I have arranged now to do a group buy on these, but instead of getting people to send me deposits etc, Ive got Qrew to send them over to me first and will send the payment back after, as that way they were all shipped at once with the one I was buying anyway which has kept the cost down.

950 Euros is the price (plus any import duty they get hit with which I will know about by the weekend as they are arriving this week) if anyone is interested, and I require a working exchange transfer box back in return or there is a surcharge.

950 Euros currently works out at 860 quid, but obviously over time that is going to vary so dont be surprised if its a few quid more or less.

So if you know anyone with a cav or a cally turbo (or some mad 4wd creation in a corsa or astra etc ) who might be interested please point them at this thread.

There are THREE available, and its first come first served.

Chip, what rating of VC are you getting in them? I assume it's the 180Nm ones.

[chip]

Yes these are the 180NM ones mate
Which is the best option for everything other than massive drag racing starts off the line, these are the best option for trackdays and fast road cars.

Its a locked box thats in mine at the moment and I'm probably going for a Quaife ATB in the near future. Are there any issues other than the standard TXB 'rules' I need to be aware of with this set-up? The TCB fluid get changed every 6k, tyres swapped between axles every month or so.

[chip]

Locked boxes Qrew really doesnt like, he says that it puts extra strain on the TXB under braking, so the first advice he would give is to put the hydraulics back.

With regards to running the Qauiffe, the only issue that I can see if you fit one is that coming out of a corner, you are going to have no wheels to steer with, as instead of the VC transferring power to the back when one front wheel spins in order to accelerate you while you still have grip on the other front wheel which isnt spinning, you will need to spin both front wheels to get the TXB to react.

For this reason personally I would stay with the open front diff (unless you are drag racing in which case disregard everything I said as losing steering response wont be an issue!)

If I was into drag racing, I wouldn't have a Cav Turbo!!

Might need to have a re-think. Can't go back to standard hydraulics, PAS pumps been ditched in favour of a Saxo EPAS one so that kinda rules out Qrews box. I don't even know if the standard system would work as I'm changing to standalone mgmt. IIRC the 4wd ECU takes a few inputs from the Motronic.

In your opinion what would be the best setup for a 350bhp 4wd Cavalier?
Std 4wd, std with Qrew box, locked box?

[chip]

You dont need to run the standard ECU to control it, you can do it on a very simple cicuit, but you do need to run a more substantial pump than the saxo one.

I beleive Qrew was looking into a volvo electric pump that might be up to the job.

My own choices for a 350bhp cavalier would be either a standard box or a qrew one, I wouldnt use a locked box as other than less maintainance on the hydraulic side they offer NO advantage over the standard box and they give several disadvantages like extra strain on the VC during brakeing which makes them less durable than standard, and the fact you are fucked if you get a puncture unless you have a full size spare.

I like the ability to just run around in 2wd most of the time causing utterly no strain at all on the TXB, and to just turn it on when I want it, so I really do fail to understand why people want to lose that ability which is the best thing you can possibly in terms of the life of the box!

[mikehayward]

here's a prime example of not enough oil changes and cooked oil - possibly non equal tyres caused the VC to over heat




damaged VC drive teeth


And damaged gear train dut to poor oil



These were taken from a third party locked box which the clutch began slipping

[chip]

Thats fair point with regards to clutch disintergration over time when talking about a badly maintained box actually Mike.

Sadly chip even the dealers from new failed to realise the importance of the transfer box oil changes and were often negected as too in the case of most garages.
If you book in a cav / calibra turbo for a service most places would just do oil and filter, maybe gearbox oil - and assume it does the txb aswell, and if your lucky the rear diff oil may be changed.

You mean people actually change the rear diff oil, blimey..
