BPX dual-mass flywheel - conversion kit available for single-mass

BPX in Ibiza, likely with over 200 horsepower.
Last winter, I installed a Sachs Race clutch because the original one was slipping.
Slipping is now gone.
'At around 2200 RPM, it makes a rubbing noise, which is probably the ZMS (dual-mass flywheel).'
I was wondering if there's a conversion kit available for a single-mass flywheel.

Can the original ZMS be reworked?

Best regards.

Today, I received the following as a private message:

'My tuner has something like that.'
From Spec.
That's an aluminum single-mass flywheel, and I hope you're aware of the negative consequences of such a modification.

If you are interested, feel free to contact me;-).
Best regards,
Alexander

PS: Since I'm not yet a 'Blaumann' in the forum, I have to send you this via private message.'

What negative consequences can be expected?

'Of course, some comfort will be lost because the dual-mass flywheel (ZMS) absorbs and thus dampens vibrations.'

It should still be drivable, right???

Has anyone had any experience with this?

Best regards.

What is this supposed to achieve?

The ZMS absorbs the energy. If you replace it with a normal flywheel (assuming that's even possible!), then there's nothing left to absorb the energy and dampen the vibrations!

The question is, when will the transmissions and drives fail, and also, the clutch will be subjected to greater stress. The first question would be: what is the torque curve of the vehicle? Is there a significant torque peak at 2000 rpm, which then decreases slightly until 3000 rpm? I would start by looking at that.

Is that really so bad? (regarding vibrations, etc.)

Are there any known best practices or experiences related to this?

'Many people also use the AFN to switch from the 1z EMS.'

Hello,

I had a customer's vehicle with EMS on the ARL, and it was rattling like crazy at idle. I think there was something loose with the clutch, because when you pressed the clutch pedal, the rattling stopped (but it still vibrated a lot).

Best regards, Rainer.

The problem is the uneven acceleration of the flywheel; with each ignition, the flywheel spins faster than it does just before the next injection. These "voltage spikes" cause, on the one hand, loud noises, and on the other hand, increased stress on everything that comes after the crankshaft.
However, I can't tell you whether your transmission will fail after 5,000 km or 100,000 km, but it will likely fail sooner than with a dual-mass flywheel.

Hmmm, sh...

What can you recommend?

A new ZMS (Zentrale Materialwirtschaftssystem) is definitely 'AFFORDABLE'.

Is there anything with extra strength available?

Best regards.

I am not aware of anything like that! What exactly are you trying to emphasize about it? The feather package?

Is the use of a ZMS (Zentrale Materialstammdaten – Central Material Master Data) mandatory only for PDs (Produktdefinitionen – Product Definitions)?

The 1Z and lower levels didn't have that kind of stuff, did they ?

The 1Z engines, unlike the 'modern' TDI engines, also ran like garbage.

The curved wave element is adapted to the ZMS, meaning that if the system is converted to an EMS, the element will no longer fit.
Furthermore, the smoother operation of the transmission input shafts makes the gearbox significantly more robust than it would be otherwise. Only in this way can 350 Nm of torque be continuously withstood.

So, you already have two reasons why the 1Z model could function without a ZMS (Zero Mass System).

Best regards, Jochen.

@ RS TDI

You wouldn't compare a 1Z engine to a modern PD-TDI, would you?

Just take a look at the torque values!

Logically, there should be factory-adjusted springs or ZMS (Zahnmodulkupplung) for the various torque loads; otherwise, the ZMS will always fail on the spring block when overloaded.

And what should I do now???

The 'OLD' zms is probably broken.

Install the new part and then what???

Getting a decent chip would be a good idea, right?

At AFN, they are also transitioning to EMS (Electric Mobility Systems), and some of their products have a significant amount of torque.
You just need to make sure to install a sprung clutch. And if you install everything correctly, the engine will run properly.
