HI All. I was curious to know, when new, why were there so few takers of the limited slip differential option?

Also, has anyone driven both limited slip differential and non limited slip differential versions of the FRP? If so (lucky u) then can you feel much of a difference between the two, when driving and does it influence the performance (on the road) greatly? Thanks.

Cost and parts availability.
I asked the projects manager yesterday.

Depends how you drive, Mine has had a LSD retro fitted.
With my style of driving it makes a massive difference, no under steer of wheel spin coming out of tight turns or wet roundabouts.
Just grip and more grip.

The best thing I have done to my car.

yea it feels like if you went round about you can go on the power for longer before the car understeers. They seem to work better on the frp keeping it in a straight line, that sounds really stupid, but it's stoped mine wandering about the road. They are expensive, and you can drive enjoyably without one. But RST diffs can be baught and refurbished for quite cheap nowerdays.

[FlashBastd]

I didn't think you could refurb them?

Hi and thanks. Interesting cost should be the reason for lack of LSD fitted, as it was only a £250 option when new, which on a car costing nearly 23K, isn't much more to pay..must have been lack of availability.

That sounds great Graham, so your abit lead right footed like me. I understand what you mean, abit like in F1 racing, when they had TC and the drivers could floor it mid-corner and the car would just accelerate away, without the back end loosing traction. Sounds fun! Was that a big job gettting the diff after market fitted also?

Nb: Really curious to know how you know the project manager for the FRP? Is that Richard Parry-Jones? Thanks.

[FlashBastd]

You have to remember that demand was much lower than expected as the FRP was already so much more expensive than the standard car, plus many were first registered to Ford as they couldn't sell them, so would often have been specified without the one option.

He was the Puma man.
the FRP man was Peter Beatie and it was the 10th anniversary meet yesterday at Duxford.
He was a speaker.
I asked why no LSD and why no Turbo.
The other 3 Fords Tickford did all had Turbo's on, and were quick.
RS200
RS500 Sierra
Tickford Capri.
My wife's Diesel Toyota is more powerful than my FRP and only 1 second slower to 60mph
That's a 7 seater...
Ok so it won't go around a corner as fast, but it can get a bit embarrassing in a straight line

Gearbox needs to be removed and stripped down to fit the LSD.
My local Ford dealer charged me £300 to do it.
LSD is a series 2 RS Turbo Escort one with a very small amount of machining required.
you can pick one up for £50 on EBay.
Make sure it's a Series 2 the ratio is correct.
I did do a post on whet you need to do to make it fit on here somewhere.

[gally]

Seriously £50! I need to know more now!

The FRP one is now £400?

I know I'll probably get kicked in the plums for this (as off topic), but how does your new Clio compare to the Puma you had?

Now that is interesting. So did many FRP owners turn up with their cars for the anniversary? What did Peter Beatie say about lack of Turbo for the FRP? I've never heard of him, is he still invloved in Special Ford projects?

Also, are you saying the LSD fitted to the FRP IS the exact same as the RS Turbo one, or did I the wrong end of the stick there? I'm also fascinated by the fact that a Ford garage themselves did the work for you! I'm not sure I'd fit an LSD to my standard 1.7 as I don't really have the need for it (not too much power for me). Though I'm sure the 30bhp over standard, makes a big difference in the FRP.

On your point about your wife's Toyota diesel, yes, standard everyday cars are becoming more and more powerful. Abit like a bog standard hatch in the 1980's could have kept up with a 1960's MG Miget or similiar. This too is happening now to our Pumas sadly..Still quick enough to enjoy though!

It was a lot more expensive, much newer, much bigger inside (except the boot) and much more powerful. I love it, and have no regrets. It is a bit juicy though!

[Dogsbody]

You will find a post on here about the Duxford meet.
I think there was 50 FRP's there on Sunday, very very interesting listening to Peter.
The LSD's used in the FRP is actually a Escort Cosworth one.
The FRP box is just a IB5 Ford one but with strengthened 1st and 2nd gears.
Peter Beattie was the project leader.

A turbo wasn't fitted as the car was aimed at motorsport and it would be put in a different class to the one they wanted.
The car was called the ST160 at one point.

There is a DVD / CD set which can be bought from the Racing Puma owners site. I expect a link will be put on here at soon.

[Big Boy Al]

graham i wouldnt like to say peter was wrong as i heard him say it too but i do wonder if he got mixed up??

as the escort cosworth is 4wd and uses a totally different gearbox the mt 75 one.

Gearbox: Ford MT75 with transfer box for permanent 4wd using viscous coupling, centre
differential, 34/66 front/rear torque split, viscous coupling, limited-slip rear differential.

looks totally different.

[happy-kat]

Also the output shaft is also shot peened.

[Dogsbody]

I did wonder my self but I wasn't going to argue
Anyway, to make a RS Turbo series 2 one fit, you need to take about 1mm off this diameter.

Take a little bit at a time until the Puma crown wheel fits over.
The Puma one is wider.

Use the Escort crown wheel bolts as they are longer, with a bit of loctite.
Then remove the bearing on the speed drive side and fit the Puma's speedo drive nylon wheel.
You then need to order in the IB5 boxes bearing for that side of the diff.
It will have fallen apart when you tried to remove it to get to the speedo drive on your Puma diff
It has like a nylon bit holding the rollers which exploded when I tried to pull mine off with the Ford proper puller.
Fit the new bearing, and you have a Puma fit LSD for your box.

[gally]

Sounding complicated i'll shall print off and consult my brother and my dad!

So ebay do these lsd's? What's the best way to machine the 1mm off? Engineering company?

Think i'll pass on doing this one...

You just need someone who is competent with a lathe and a Puma crown wheel to size it too.
I think I took 1.6mm off to make mine a drop on fit.
Took me about 15 minutes to do, and 10 of them was setting it up to run true.
Look in you local business guide, one thing this country does have is lots of small engineering companies.

I thought your FRP already had a LSD fitted Chris?
Unless you are doing another

[mikecat]

yeah i took mine to an engineering company. Charged me 20 quid to do. And it then fitted perfect

[Dogsbody]

I spoke to someone else last night having one fitted.
They have just given it to a gearbox specialist to do.
