long time since i've posted in this room, when we built my S1, i fit a clutch i found in the cupboard as a gamble, it slipped..

So i bought a brand new LUK from Matt Lewis, fitted etc,

It slips when you load the car up, doesn't if you set off from a standing start, but if you say join motorway and put your foot down in 4th/5th to catch up with traffic, it slips

Car is standard completely bar a chipped ECU and 14psi of boost, which a standard clutch should cope with more than easily.

Flywheel is flat, cover plate & release bearing new when LUK fitted.

Any thoughts?

I can't help but I have the same problem but with a new 6 paddle? Which should be overkill for my set up flywheel was machined flat all fitted with complete kit for the clutch do they need bedding in? Got mixed answers doesn't slip all time same as yours catching up with traffic won't from start

My 6 paddle slipped from new in 5th gear on a freshly skimmed flywheel , let it bed in for a few miles and it should start gripping mine did and never slipped again

needs a good clutch[uprated] on rst if modded well.
ok in lower gears but the torque kills it if pulling a high gear
i remember this from the 80s/90s

kinda different from the cossies which [certainly on 2wd] a std good clutch will take stage 3/greens etc

Standard clutch can slip at that, you should be around 170bhp and similar torque which is on the limit (some will take more some less depending on brand).... turbo the boost down a few PSI and see if it no longer slips mate.

Am I imagining it or does a s1 have a smaller clutch than a s2? Might be worth fitting a s2 flywheel and clutch?

Had this problem with my fabia vrs which is running big torque. Fitted new Sachs DMF, clutch and slave and it used to slip in 5th and 6th gradually got worse and was worse than the original clutch I originally replaced. The slave popped last week so put a luk clutch and slave on, did 50 miles and it slipped slightly in 6th when on the a1 but put another 100miles on and it's now spot on. Don't know why the Sachs stuff slipped, I went for that because it was OE stuff but chances are it just needs bedding in. I'd never heard off bedding in a new clutch but has sorted mine and it's quite common too if you google it

hav always had this problem with my s1 would be interested to know if you sort it

As Karlos said. I had a 3 month old standard clutch slipping at around 165bhp. Exactly the same symptoms. Would only slip when building boost from low revs in a higher gear.

moesin2005

so needs upgrading then

You're right , S1 is 200mm and S2 is 220mm

moesin2005

already have a 220mm one in

Mine is an S2 item so 220mm, i thought it might be on it's limit but having had RST's in the past with a standard clutch, i thought it'd suffice.

The car's done about 1500 mile on the clutch so far.

So what are people using nowadays as a sub 200bhp clutch as i don't want to fit a paddle.

AP organic Andy

AP organic.
I tried helix but it was far too aggressive for normal driving.

Karlos G

iTrader: (4)

Specifiacally the AP Organic CP2000-8 good for 230bhp and similar torque.
As everyone has already said S1 does indeed use a 200mm clutch vs the S2 220mm.

Thanks folks. Is that just an AP organic spinner or cover plate too?

Best get saving, one for Fiesta and one for S1

Chopshop85

Clutch and plate. You'll need to do the pedal mod as well.

Roscopeco

Not for big lads that task

Take the drivers seat out and be prepared to have a sore back for a day or two.

Already have the pedal mod as did it when the car was built

Thanks chaps

Not sure if your noticed my posts on RSOC mate but I had the same trouble, stage 1 MSD with standard clutch. Drove fine for 500 or so miles then as soon as it came on boost in 4th and 5th it slipped. Gearbox out, new LUK clutch and still slipped. Gearbox out again, flywheel skimmed, AP organic and pedal mod/alloy quadrant and finally I can drive it again!

martinmilne

I've not done the pedal mod what are the gains would it cause a uprated clutch to slip on a standard pedal?

Sorry to keep asking questions on your thread Andy

Romey

Without the adjustable pedal I`d of thought you would have selection problems , my pedal was nearly through the bulkhead to get a gear. It was either on or off, now it`s nice and smooth and selects gear HTH

Chas

Is there anyone here who has used a stock cover on a 4 paddle clutch as well as an organic clutch on a 200BHP Escort?

I ask as I am looking to change mine. Whilst I am aware that a 4 paddle probably will not last as long how they compare in feel etc? I understand that a stock covered paddle clutch will be , but judder slightly, but not as much as a full paddle clutch kit and be lighter to boot.

turn boost down to 10psi and it wont slip. as said the limit is aroud that.

then I would fit 4paddle with higher pressure std cover available off burtons.

after that I had a custom clutches made by helix for pretty much any box we would use.

studabear

I have a alcon 6 paddle and standard luk cover and it copes with what my zetec turbo is producing. it did start slipping on boost in 5th when we was mapping it at 18psi but it was possibly due to how hot it was as we was up and down a dual carriageway for a good while.
