Just wondering how many of you guys run a paddle clutch. Was after some feed back on what youve experienced with launching at hi revs and clutches for track use..
Im new by the way.....HI guys

Skippy,
Most paddle clutches [ ceramic material ] operate like on / off switches in my experience. However, they are probably essential if you intend to beat the death out of it on the track and strip.
It will depend upon track time / versus road time. If you travel a lot in the car then the paddle will **** you off quite quickly.
Another factor is the power that you have. l'd suggest that a decent competition organic clutch, AP or Exedy, will take quite an amount of abuse and be useable on both road and track until you get into the higher horsepower / torque ranges. Say; 380 hp / 360lb ft as the changeover point.
If you go ceramic then you'll need a steel billet flywheel, Cast ones rip to shreds and judder when ceramics are asked to do their stuff.
That help??
Good luck David APl Engines / APi Impreza

I have the same clutch as Wallis, no probs with judder... not on and off switch but handles 500hp and torque on my car and i expect more on wallis car.
Not a great deal of difference drive wise over an organic, so much so that my best mates 320hp car is being fitted with one so that he can use it at santa pod without worrying but still drive it as normal day to day..
Rob
p.s. clutch is LateralPerformance paddle

Mine (Same as rob and david) lasted 8000 miles, predominantly road use, including holding the car on the clutch, which is not good for paddle clutches.
The car got driven VERY hard on road and off, including several 7500rpm launches.

Tony, that was about 4 months driving!
It had been a while since i last had a paddle clutch, 1998 in fact, and forgot that they dont like being held at the biting point, ie slipping the clutch. Being a lazy bugger in town, i dont use the hand brake. Thats what killed it.
There was no judder or any signs of a problem, until about 2 weeks before i took the engine out. Removing the engine showed the clutch was worn to the rivets and had gauged the flywheel.
Going with an OSG twin plate now, although the thought of paying 1200+ for a clutch and flywheel hurts!

Steven,
You're just a yob![Wink](https://www.scoobynet.com/images/smilies/wink.gif)
IIRC, last time I spoke to Stan (Smith) he'd done over 20,000miles on one of my paddle clutches, but I don't know what he ended up getting from it.
Mark.

same here.
500lbft and no problems on an LP paddle clutch.
Some find it a little tough to use (eg. rob likes to stall it) but I have no idea why. On a smooth flywheel I can barely tell it apart from a normal clutch, yet it handles big torque without a problem.

Ran a sprung centre paddle in my hill climb 911.
Two years/6000 miles and it was dead.
Welded itself to the flywheel once after a VERY hard tyre warming pre start (Ex drag racer here...)..stock clutch much better and lasted longer.
The secret is a sprung centre. The 911 is a cable clutch too.

911,
I agree, certainly if you want the gearbox to stand some chance of surviving.
If the plate welds it self to the flywheel, it's because it's being slipped too much. The plate gets so hot, that the metalic particals melt, and when it finally stops slipping, it welds it self to the flywheel as it cools.

20,000 miles sounds a bit better. I can be lazy in town too and have the clutch on the biting point... guess i'd have to change my habits. I do like the thoughts of the LP paddle, sounds just the ticket if i can make it last 20,000 miles then i'd have no problems.
Mark... how much are you letting these go at? They're not in scoobyshop anymore iirc. Will go nicely with one of your flywheels which is sat in the garage
.
Tony.
P.S Steven, the OSG clutch/flywheel that my friend runs in his track Gti-R is a work of art. So smooth in operation and handles the torque beautifully. Sounds a lot of money but i don't think you'd be disappointed.

Interesting comment from David re. the stock cast flywheel and paddle clutches - I've run one for the last 30k kms with no problems on stock (lightened) flywheel, except it being a complete b*stard to drive in stop/start traffic. It judders *very* badly (unless launched in anger, of course)!
I always assumed this was due to me using a pressure cover from a different manufacturer (correct one was balanced along with rest of rotating assembly on ej25 build. I've just received a new clutch disk ready to go in when I fit the new motor. This will also be with an LP flywheel, so hopefully problem will go away (clutch itself has a sprung centre).

PMSL, last year it looked like a bag o sh1te, only way it could look worse would have been to rear end it into a bus or add lexus lights. (the latter being the worse)

Tony,
I'm sure you appreciate that it's impossible to guarantee someone will get a minimum of XXX miles out of a clutch, particularly knowing how some of you lot drive![Big Grin](https://www.scoobynet.com/images/smilies/biggrin.gif)
YHM (shortly).

I spoke to EARS about the Alcon, they were a bit sketchy about it's torque rating and i didn't get if it was a 6 paddle/5 paddle etc or if it was a sprung centre.
Cost was "230mm kit £379.25 plus VAT" NOT including the release bearing.
Be interested if anybody had more info... but think i'll go the lateral route. many more people running these.
Tony.
P.S Never heard of the Alcon flywheel tho.
