exedy organic uprated clutch judder from new
HI there im very new on here (2 mins ago) but hopefully i will be able to navigate my way back here...... ok i have just fitted an exedy racing clutch (organic disk with 40% more clamp load plate in the red box says racing clutch). my car is a 2000 classic uk turbo version 5 and had a standard clutch in, standard clutch was not slipping and i had no issue with judder when pulling off or changing down gears at low revs (approaching lights).......... now i do have some judder, i can deal with this but is this normal for my exedy organic uprated clutch when brand new? will it get better? i have only done about about 10-15 miles on new clutch and only pulled off at low revs as i expect it has to bed in properlly. reson for not much use is due to me changing my standard exhaust manifold with a stainless equall length feral racing manifold and have been told i should get a re-map before driving properlly (as intended)... is this true that the clutch judder is normal for my clutch????? and do i need a re map since fitting the manifold????? please help lol thanks.
oh and last but not least... DO I NEED TO REMOVE THIS 'ORFICE'??? im happy with the pedal feel as it is, just not the judder

I had an Exedy Organic clutch fitted yesterday at API. The mechanic expected my flywheel and said it looked ok, so it was left as is. There's no sign of judder on mine.

Yeah, but look at the size of your feet Daz !
PS good numbers on your latest roller session with the Simtek
Sometimes a clutch needs a few launches to get 'high spots ' off, Don't worry just yet Mr RS250gtracer , but if it it did go on a damaged flywheel, then that's what l would expect. We can help you with your remap and so-on if you care to call me.
Funny, some people seem to get a bit of judder with the set up you have BUT we never experience it with the ones supplied by us. Either fitted here or self fitted.

Where's the smell coming from? You after the launches?, or the clutch
Is that one of my Exedy's we are talking about here? It'll be a first if ti is.

David,
I was asking if I launch it hard to get rid of judder will it smell??
Its one of your clutchs which you fitted for me, Seem to have a Judder when pulling off, Anything you can suggest?? You said to me when I emailed you to give it a while to let it settle down, but its still doing it 4,000 miles later.

You'll need to tell me the year of the car to decide if Ecutek fits, as it is 99 car onwards, no matter UK or JDM type.
We are close to Junc 12 of the M40.
Usually speaking there is a gain of about 10 % by remapping the car the first time. So a 280 hp car ends up a bit over 300 maybe 310 ish. lt depends upon exhaust and so on and how the car 'accepts ' the upgrade. Some do better than others. But tell me about the age of the car and what is done now and l can advise better.
As for clutch judders a couple of launches usually settles them down and yes, it does make a smell as you are burning off the ' high spots ', but it should only last for 5 mins or so.
All 4wd drive cars are prone to a small amount of judder it is a function of the grip levels against the clutch grip. Mostly the Exedy from me seems not to be as bad as others dunno why. Perhaps it is our devotion to ' providing the best product around at a competitive price ' policy.
AND if you believe B/s [ sorry positive publicity ] then that is the reason.

Surely you're winding me up ?
Launch is exactly that. Once installed, engage 1st gear, bury your right foot to the floor, the engine hits a preset limiter, say 5000 rpm. [ mine is set at 6200 ] Then you just take your foot off the clutch. The engine drops a bit of timing and applies heaps of boost and away you go.
That is a simplification, but you get the idea.
