6-speed DSG maximum torque

[JACUPRA280]

Hi all. I can't find a decent answer to this, so here goes:

The 6-speed DSG in our Cupra's is rated for 350nm / 258 lb /ft according to Volkswagen "The 6-speed is paired with high torque engines (up to 350 Nm)" [Source]. Curiously, it's rated for the exact torque output of the Cupra stock.

And yet, I understand lots of people have had their Cupra remapped. At a bare minimum, the torque from stage 1 will be 300 lb /ft.

My question is, how seriously should we take what VAG tell us? Can this DSG box take a lot more power than advertised?

I would be very interested to hear from members who have a remapped Cupra. Have you noticed anything off with your gearbox since it was tuned? How's the clutch faring?

I imagine they state the gearboxes maximum torque as being the same as the engines output to discourage people from tuning.

I'm sure the 'boxes are engineered with much higher limits to protect themselves from the warranty claims that would occur with harsh use or harsh environments.

I would imagine it is down to the clutches within the DSG system that would be the limiting factor. You can't expect a clutch/s to last as long if it is working at it's upper limit or beyond.

They probably advertise 'middle ground' figures to play it safe. Pointless putting cars on the road with components close to their maximum operating tolerance; how many would go bang?! Not great for your reputation. There will always be a trade off between performance and longevity/integrity.

BUT you still need to be able to judge just how much more power the box could take. VAG group produce DSG's capable of 550Nm in a 7 speed box so what makes these different from the 7 speed wet boxes with an advertised max torque limit of 380Nm?

As said the question shouldn't be how much torque it can handle, since it's really strong and even the above mentioned 550 nm will work (for some time).
Question is how much it can handle under all circustances and for an acceptable amount of time.
Dutch / German tuners have enough experience wit the cupra DSG and they all limit the torque in certain gears and set it to a maximum in (heard 450 nm).
Know a few guys that drive tuned cars with this type of DSG and the all are trouble free but the early adapters had their software adapted a few times to prevent the dsg from slipping.

The DSG box on the Cupra (as in the Golf7R and Audi S3) are limited by the software to 450 Nm of torque.
The Mk2 DSG 6 speed were limited to 350 Nm (was not available for the Cupra then but it was available for the FR-TSI 2.0 litre).
You want to get it to handle more than 450 Nm of torque a tuner (like APR) must alter the software to increase the clutch pressure and set the software limit to a higher value.
When done it can handle easy at least 500 Nm of torque.

Are you sure, that doesn't sound quite right? I don't think the wet clutch 6 speed can handle 500nm on the stock clutch as a daily driver... maybe if it is only driven occasionally if I was to go for serious power I would upgrade the stock clutch I think. At least then I would t be bricking it under full load.

It does sound right 4sure!
The adapted DSG box will switch gears quicker and you won't notice any degrading comfort.
It can handle even more that that but they don't want to stress the clutch to it's maximum boundaries.
People are driving with 510Nm with upgraded DSG without any probs and no influence in daily drive.
Just works well.

with 450nm my gearbox is perfect, done 30k km so far , not an issue

 

[Wayne mason]

Have you had the gearbox maped mac ?

with 450nm my gearbox is perfect, done 30k km so far , not an issue

I am not sure a mere 30km of driving is enough to assess impact of the additional stress and wear on the clutch in any real sense...

 

[Deleted member 103408]

I think he means 30 thousand not just 30.

 

[davidstarkey11]

350nm max advised I believe but up to 500nm is manageable. Anything over you'd need an upgraded clutch and a DSG remap at least.

 

[LouG]

Aren't Cupra 300's rated at 380nm?
As for longevity, a DSG is far kinder on gearbox internals and clutches than your average human. Quick shifts, ign cut on up shifts and consistent shifts are all easier on the drivetrain.

I thought the official figure for the 6 speed on the Cupra was up to 450Nm.
