Hi Steve

If you look on the picture above the scavenge port can be scene directly below the output shaft. On the picture below the return port can be scene at the top right rear of the differential casing. The return will feed directly onto the pinion where it meshes with the crown wheel.

The ATB differential runs significantly cooler than the LSD fitted to a ZF/RBT so excessive oil temperatures should not be generated inside the ZFQ.

regards

Chris.

Wow Chris... you are a lucky boy.
To be capable of selling so many units on the base of a nicely made CAD drawing is really meaning that you are a great commercial.
About the car testing.....it is also a bit of luck to have a vehicle at your disposal......but what's about the test driver?
Are you not affraid to customise the unit to close to the driver wishes, and probably missing the 50% driver requirements???
Isn't it one car too little for a full development of a transmission???
Normally you would need 2 or 3 cars at least.
One for dynamic endurance, another for functionality performing and another doing a sort of car life endurance test in the hands of a non professional driver ( 50.000 kms are sufficient )
The risk by leaving to the professional driver the full power to set up the fine tuning is as I told before, a customisation to his desires and a NON perfect fine tuning because he is capable to drive even with minor troubles untill full assuefaction of them is completed, and leaving them to the NON pleasure of the final clients.
But you know your job better than me.

This would probably generate premature hydraulic pittings.
Spray in the exit like all the Porsche and many other boxes are doing.
Again it is not a race box.
It sounds like it is designed under opinionism imputs in state of being designed under experience acquired.

WHAT??

Why don't you just tell everyone about your product with Goran and the name of your American distributor as he is to shy to reveal himself? You have your own thread, please go there and stop worrying about what we and Quaife are doing.
I appreciate you are in the transmission business and a commercial competitor and are trying at every opportunity to spoil what we are doing but please stop and take on board forum rules and ethics that have already been explained to you.


Regards

Chris.

I agree with Chris!

What Chris and Quaife are trying to do is to produce a modern and affordable alternative to the ZF/Porsche gearboxes for the GT40 market etc.
Some of Wanni's comments probably do apply but if you want to put that degree of research and development in a gearbox you are just going to put the price into the range of plenty of other gearboxes that are available on the market and even at that most still will only give 1 years warranty.
Having used Quaife products for years in motorsport i think they will produce exactly what is needed.

I give up......:(

I have no horse running in this race or any other race come to that, but that must rank as probably the rudest statement I have ever witnessed in nearly 4 years on this forum and that includes Oliver and Meat.

I notice the language was suddenly no barrier in that classic piece of sarcastic character assasination that began: "Wow Chris etc..."

Sorry, this is just not on, don't forget, Quaife, a long standing international company with a first class reputation is involved here too. Whatever must they think of us?

If the intention is to promote his own & Goran's products using this media, by actively detracting from others, then the strategy is bound to fail.

And don't forget to dig two holes mate, one for yourself....

Sorry Mr W, I'd better explain that in plain English in case the expression is not familiar in Italy......

:rolleyes:

If you set out to bring someone else down, you will also bring yourself down as often as not...
 
I think this is a blatant attempt of points scoring from Wanni, yes he probably is very knowledgable about gearboxes, although I have never heard of his company.

But he comes across so desparate for dialogue on technical aspects of gearbox design and construction. Most of his technical blabber should be directed at Quaife, but then I think we know what there response would be.:lol:

I think Chris deserves a medal for patience.....................:eek:

Mental note to self give Gearfox Automotive a miss, if this is an example of there aftersales and tech support,,:dead:

Next
 
If open dialogue means to be allowed to become offensive in a pubblic forum..................some basic rules are missing.
Everybody is free to do it privately on [email protected] and i will feel much more free in answering in an appropriate mode.
Best Regards

Sorry Chris,
I apologise for using your space for answering to personal chats.
Now it shall not happen anymore if the guys wanting to have a chat with me will be so kind to use my private account.
BYE and good luck.

Hello Wani

Considering your most recent posts on this thread, together with the quotes I include above, please accept this message as a POLITE WARNING.... (The first I have felt compelled to write to date :()

You are obviously a well established designer/producer of transmissions and I accept that with the language differences, some of your posts can be easily misconstrued but the tone and underlying content of your latest posts on this thread are very badly worded and worse than RUDE!! - There is a tone in them that seems to attack and undermine what Chris and Quaife are going to produce and it is most unwelcome..:mad:

Admins and Moderators do not look to ever 'censor' any posts, (long may that continue) BUT the forum is for 'constructive input' so please at this point keep to 'your own words' and not post further on this thread unless the comments are both constructive and not masking another tone/agenda.

I look forward to hearing future input from you on other transmission related matters, on other threads.... Please....:)
 
As a very inexperienced observer on this forum I would normally leave a response to this posting to those more knowledgeable than myself. However, I feel compelled to say something.

Chris, at the risk of sounding condescending I think your patience on this thread has been incredible, and your responses restrained. In my opinion Wanni’s last post smacks of sour grapes. I understand he is passionate about his product, but he appears to be the best salesman you have at the moment.

As another inexperienced observer just getting started in this field I would have to agree completely. Wanni is obviously worried your product is better than his own.

As a partner with Chris in this project we spoke on the phone many times about the best course of action with regard to Wanni and his comments. Enough became enough, hence the reply from Chris.
Thanks everone for your obvious support. This is a large project and one we are working hard to get right for everyone's benefit.

Regards Martin.
 
Hi all,
the AGITATOR is here, taking his responsibilities.
1) As I already said, I am not worried about this application ( FORD GT 40 ) because my unit does not fit.
2) try to be all relaxed because by developping my unit, I ahve already drawn the " MAP OF THE SHITS ", and I suggested Chris to be carefull where he put his feets.
3) AGAIN.......you can see my unit in perfect operationality on many vehicles.....all the rest is still theory.
THE FACT is that all the replies from the PUB ENGINEERS were based more on skin simpaty that on real position on this matter.
NOW TO CHRIS:
you are free to sell anything you like.....but if you have some kind of principals......do not attempt to people life.
I have been on a car at 270 km/h with the ( MY ) transmission locking in an instant and I am still thanking the drive shafts manufacturer who is using a good material but not the best.
If you feel my stimulation to do a superior job with the conseguence of a successfull business, do not treat me UNPOLITE, but you are a dangerous unexploded bomb standing somewhere being ready to explode at any time.
TO ALL WHO DOES UNDERSTAND MORE THEN A TORQUE CONVERTER....thank's a lot for your understanding. To all the others....keep boiling in your pot. One day will come that you will burn your fingers. After that you will be affraid to put your hands even under cold water.
A BUON INTENDITORE, POCHE PAROLE.
Dear Chris, untill I feel that you are taking other people life as a concrete risk, I will be here telling it to everybody.
Ciao

Quaife have been in the business of manufacturing transmissions for 42 years you only since the late nineties, (some seven or eight years).

You also assume that everyone that opposes you has no knowledge or experience, I am an ex Rolls Royce trained and qualified aircraft engineer, specialising in the deep strip and build of aircraft engines. I also specialised in the secondary power systems (Aircraft gearboxes) fitted to Tornado fighter aircraft costing many millions of pounds. In addition to this I hold a Higher Certificate in Mechanical and production engineering.

There are many contributors to this forum that are experienced engineers and your abusive and threatening rhetoric is unjust and uncalled for, As the CEO of a company you should act in a dignified manner and have behaviour and language to suite, you do yourself no favours acting in such a manner.

regards

Chris Melia.

PS. The ZFQ feeds the return oil to the exit of its crown wheel and pinion so cavitation or hydraulic pitting should not occur.

Regards

Chris

I suppose I'm a pub engineer today. However I did serve a 5 year apprenticship (including design and development) in a transmission plant manufacturing final drives and gearboxes for the auto industry and like Chris have an HNC mech eng. I also have great faith in Quaife's long standing reputation. Ordering a box from them is like pre ordering a new Porsche or BMW site unseen - you know that it will be based on the culmination of many years experience and that you are not going to be disapointed. I have told Chris that ZFQ is the route I'm going down.

Language problems apart we have an interesting clash of Anglo Saxon and Latin culture me thinks.... (ho ho ho....) But isnt that how the GT 40 was born?

ps no offence! I frequently holiday in Tuscanny and like the Italians

IMHO Chris is doing the right thing. He is employing the services of a well established maker of gearboxes which see some extremely hard useage with a great deal of success and reliability. Quaife know what they are doing.
The box will fit any GT40 and has the ZF external dimensions which will suit many chassis. This is what we have needed for many years. Those of us who run Renault based boxes will be glad to get a box which will allow a powerful torquey motors without the need for endless expensive upgrades with still questionable reliability. I appreciate that Wanni has a lot of knowledge regarding this subject but would be happier if he kept his input to making more positive comments which everyone would find more helpful.
Incidentally my order is the first one in the ever lengthening queue for this new gearbox which I am sure will be well designed and built and be a great success.
