Westfield build manual states that Sierra XR4x4's come with standard or LSD's, or Westfield kits can be supplied with standard or LSD's? There is a world of difference.........

Blatters, I posted in this thread Westfield state in their build manual Seirra 4X4's come with either standard of limited slip diff, not that Westfields cars have an option of standard or limited slip diff. So I don't know where you've got that from ???  However, so are you stating this information in their build manual is b*****k. I personally don't know, unfortunately like others I had confidence in Westfields knowledge.

Windy's comments have come across to me that no one is listening to your comments. Which he feels is wrong and he finds it necessary to state this to the world wide web. But I don't expect you to disagree with him, being SS mates and all that and me being a newbie. Best left there.

I think perhaps that the written word and sentence structure may have upset you from Blats and Windy  ;)  :down:  :(

But I don't expect you to disagree with him, being SS mates and all that and me being a newbie

I can assure you 100% that if either Blats or Windy had noted something incorrectly ........ they would have been told of their error  ;)  :) without any SS mateyness and no offence being taken.

There surely isn't any intention of winding you up

It is not unknown for the Westfield build manual or verbal comment to contain "anomalies" when trying to cover so many variants  ;)  :) with specialist parts supplied.

No-one is perfect

Without going into public debate "this is not the place" but (trust me on this one) Windy and Blats have a very experienced background  ;) with car parts, spec and construction  :D they are some of the most helpful guys around  ;)

Must've missed it, or I mis-understood the piece I quoted. Sorry.

Not really. I don't treat you with any less respect than I would anybody else, just because you're a newbie.

My respect for Windy's opinion has nothing to do with Speed Series cameraderie either, and everything to do with knowing what he does for a living. In fact, we've had to agree to differ on several discussions in the past.

I'm not in the habit of revealing "personal" information without the express permission of the individual concerned, which I know is frustrating for many people, especially newbies who aren't as familiar with some folks as us old timers. I'm sure if Windy is disposed to, he'll tell you a bit about what he does. Suffice to say that he is *far* more qualified than me to comment on car dynamics, and also has some experience of the failures he coments on, IIRC.

However, so are you stating this information in their build manual is b*****k. I personally don't know, unfortunately like others I had confidence in Westfields knowledge.

I understand. It is frustrating when you stumble across information that contradicts what you have been told by a manufacturer, especially if it has cost you money/time/effort trying to do what appears to be the right thing. One of my "life principles" with stuff like that, especially now with the internet, is to check what I'm being told. This applies to almost everything I buy, and it certainly applies to anecdotal information, as well as sales brochures/talk when the information is supplied by some-one who wants to sell me something. I'm becoming a very sceptical punter in my old age. It also explains why my search techniques are well honed. I spend a lot of time searching for all sorts of information........

Mark I'm sure they are and I apologise if I have offended Graham and Mark.

Personally, to many newbie's, I'm sure, this Forum being full of technical help and very knowledgable individuals does at certain times discharge the air of owners club and your not invited feel, but we continue to criticise the other side 'Caterham'.

I just wish we would all realise this is a world wide advertisement for our organisation and not suffer from one upmanship. I know i've been guilty so I am a ******      :D  :D

Hopefully, the technical advice can be posted continually without too much banter.

Right thats me. I'm out   :cool:  :cool:

Question

7.5" LSD's would almost certainly be from a Cosworth variant, or *maybe* a high end Grandad . Not sure which though......... :0

A trawl of the interweb (or a phone call to a Ford Motorsport dealer, or specialist Cosworth supplier like Graham Goode Racing, or Brodie Britain Racing, or a transmission specialist like Road and Race or SPC) would, I'm sure, furnish you with an answer.

Ive 7.5" Diff with a 4.27 ratio out of a Granada. I then added a Quaife ATB lsd.

Its a cheap way to a 4 plus ratio without having to spend silly money on a c&p

Cossie diffs are pretty simmilar, just bigger driveshafts iirc and they take 500bhp pretty well

Cosworth diffs (the ones fitted to the RS 500's) were plate diffs, which are completely different to viscous ones in the way they work.

I didn't read Windy's comments as sarcasm. He makes some valid points which need to be considered. He may not have constructed the sentences very well, but he wasn't trying to p*** anybody off........

Yes it is a common fact that engineers are poor at English :D  :p

Yup, but even the viscous lsd from standard 2wd and 4wd safs are taking 500bhp with few problems, normally aspirated engines shouldn't be a worry, unless the characteristics of a viscous lsd are unsuitable

OK. Got my diff apart.....it's an Escort diff, but the internals will be similar enough....

Picture 1. Crown wheel and pinion.
