Madness Uprated Clutch on JTD - Suggestions / Experiences

I'm looking at remapping my JTD next year..

Any suggestions or experiences on uprated clutches for the 1.9 JTD 16v ?

My original is getting near the end of it's life so when it does need changing I might as well put a better one in ready for my re-map

Re: Uprated Clutch on JTD - Suggestions / Experiences

bear in mind that uprated clutch materials usually have less miles in them.... a stronger pressure plate will be harder to engage for your left foot....

what would you want the upgrade for, more miles, or coping better with power?

You need a stronger pressure plate. My clutch is nowhere near worn but after a remap I can easily spin it at low revs and on high boost.

Thats who supplied the uprated clutch for my 2.4 JTD. Standard friction plate but more clamping force, however when fitted it was actually much softer than the old worn one.

Yep, uprating doesn't necessarily mean having a heavy clutch pedal.

Re: Uprated Clutch on JTD - Suggestions / Experiences

I gave CG a ring about getting mine uprated and they seem to know what they're on about but they're not cheap.

I told them I've got a remapped JTD Alfa 147 and they knew instantly what one to supply. Just waiting for it to fall apart and I think I'll go back to them ... and maybe a Q2 as well!

Re: Uprated Clutch on JTD - Suggestions / Experiences

I think they do two types of uprated clutch Dibby, one is just a normal friction surface with increased clamping pressure, the other is a proper fully up-rated clutch. I got the cheaper one for £130, same as a new clutch from Alfa anyway.

Re: Uprated Clutch on JTD - Suggestions / Experiences

I asked them about the cheaper one and they said with a remap on the 1.9JTD I'd be looking at the properly uprated one at over £200.

Thinking by the time the labour charges are added on and I might as well get a Q2 in there at the same time, £70 extra isn't a great deal if it's going to last.

That standard clutch is still holding together though, still staving off the bill!

Re: Uprated Clutch on JTD - Suggestions / Experiences

I have a clutch slipping problems on my 147 JTD 16v multi-jet 150HP, it is not remaped and it started to slip in higher gears and engine reving at about 2000 rpm. Now I was thinking of remaping the engine in the near future, so I need to upgrade to something stronger than the original stuff. I was thinking about the clutch from 1.9 JTDm 170HP from Ducati Corse or GT QV with 330Nm of torque. I found it in the ePer, the product number is 71752488, and it is actualy cheaper than the original clucth for the 150HP engine... Good old Italian logic at work there?

And after that I was surfing around the ePer and found the clucth for the 2.4 20V JTD multi-jet from 156 (product number 55192735). Looking at the sketch it looks almost if not completely identical to the one for 1.9 16V engine. Does anyone have an idea if it is actualy possible to install clucth from the 2.4 20V into the 1.9 16V? Price is the same for both parts... so why not and it is designed for 400Nm!

Re: Uprated Clutch on JTD - Suggestions / Experiences

Sorry to bother you but can you explain that.
So you are saying that it is sure that 2.4 20V and 1.9 16V clutches are interchangable?

Or are you telling me that 1.9 150 and 1.9 170 clutches are the same?

Re: Uprated Clutch on JTD - Suggestions / Experiences

The only problem with remaping and uprating the clutch is the DMF should be changed with the clutch to prevent Judder on take off. The old one will be orn and wont last long with the new work done.

Do the 1.9 16v have a DMF? I thought it was only the 2.4 20v? Or is it all jtds 8v and 16v?

Thanks.

Re: Uprated Clutch on JTD - Suggestions / Experiences

ALL JTDs and JTDM, 8, 16, 10 or 20V have a DMF. You had me thinking then but I've confirmed it on ePER.

Re: Uprated Clutch on JTD - Suggestions / Experiences

Hey all.. Oldish thread i know

But as this thread is related to my issue i thought i'd post here
It keeps all the info in 1 place as well..

I have just upped the power on my Wifes 150bhp 2.4 JTD. Not sure of the increase but it's a fair hit.. It spins the wheels very easily of the line and torque steers like a Torque Steery thing

Straight away though, i noticed the clutch slips at around 1200 to 1700 rpm It's ok if i fether the throttle until i'm above 2000rpm them floor it. But that kinda defeats the object of the more power

So ! Is my clutch on it's last legs ?? Or is it the increase in Torque that is making a more than healthy clutch, just slip because of the extra power ?

If it's the extra Torque then i'll put the power back to where it was and continue as normal until the Clutch starts to slip under normal conditions.. I can't afford to throw money into a new clutch at the moment if it's just for the sake of more power
The power upgrade is also a Fuel Economy mod as well.. So it would be silly to gain 15% better economy, but have to spend 300 quid upgrading the clutch

So would you say it's on it's way out anyway or maybe the increase in power..


Cheers

Wodj

Re: Uprated Clutch on JTD - Suggestions / Experiences

My clutch did that when I got my old JTD remapped, I changed the clutch and it didn't slip once in the next 20k miles before I sold the car. I think you either need a new clutch or to remove the remap (if you can't just drive it gently).

So looks like the increase in power

No, Ducati uses different clutch, or at least it has a different part number in the ePer.

So Alfa decided to upgrade the clutch with only a 20 bhp gain....Interesting.
