Remapping '00 Xantia HDi, how will the clutch fare?

Post by Dane »

Hello everyone. I'm a new member from Denmark.
I'm considering a remap of my 2.0 HDi 110, but I am concerned about the clutch. I've had a local HDi remapping expert recommended to me. He can lay out the file so it won't be too harsh. The car is in excellent condition, very well kept. What is the good members of this forum opinion on this dea? How will the clutch handle extra torque? The promised output is 140hp and 320nm (I'm sorry, I don't know foot pounds, I'm from Denmark )

Hi Dane

If you drive using all that torque you run you always run a greater risk of the clutch failing, driven gently even a worn or slipping clutch can last many thousands of miles, so it really depends on how you drive it.

The same clutch is used in the TCT engine and that clutch will hold 150bhp from the factory, i would say you should be ok. But as said if you sit there slipping the clutch doing fast starts etc you'll soon kill it, as you would any clutch.

How many miles does your clutch have on it anyway?

The bhp is not the problem its the torque, I would suspect that the diesel will be somewhat higher.

As long as the clutch is fully engaged as in foot completely off the pedal prior to applying anything thing more than a very low amount of drive the likelihood of clutch wear will be significantly reduced. I know from my experience of doing advanced driving instruction that a significant proportion of people rest their left foot on the clutch pedal even though they have no intention of using it at that moment of time. This reduces the pressure on the clutch plates and allows the clutch to slip under full application of the drive.

If we exclude abuse through excess slipping then it should survive ok. Ultimately it should not, theoretically at least, last as long, but in practice I doubt it will be an issue.
The extra torque if anything should help at low speed by reducing the need for slipping.

One of my XMs which had covered about 250,000 miles - I believe on the original clutch - started slipping but it was only at about 2000 rpm with your foot down, point of max torque, As soon as I realised it was slipping I didn't allow it to any more by backing off, the clutch survived until I sold it at 292,000 miles and was still perfectly driveable.

I dont think the power increase your going for will do any damage to the clutch at all, clutch life is all about how you use it not what power its running, especialy with the sort of power levels we are dealing with here.

As everyone else has said dont slip or ride the clutch and dont go doing snatchy full bore gear changes and it will be fine.

Good luck

Leaving aside damage from poor use of the clutch the design capabilities are related to friction surface area and material properties.
The existing clutch plate will be around 228mm dia for 110 hp.
Typically Citroen would specify a much larger plate for 140 hp with a diesel.
As an example 242mm on a diesel 2.5TD XM.
The harder diesel friction material will be specified in both cases.
Torque concerns them more than hp as the same size 242mm dia plate is used at 200 hp for a V6 petrol but with a softer friction compound.
Uprating a small clutch will present little extra damage risk to a competent and careful user.
Abused though is another matter altogether.
A number of 2.5TD's got chipped by owners some of which then wiped their clutches in way under normal life.

ive a tuning box fitted to my 110hdi which gives about 130bhp.. and ive done 41k with it.. clutch ive no idea how old it is.. but im now on 201k miles and theres still no premature slippage at all.. in fact it refuses to slip even with a boot full of all my tools etc.. she prefers to spin wheels.. i do though do a lot of dual carrage driving. but my point is ive not needed to do anything to my clutch in the 41k miles ive done with the tuning box on max.

Thank you very much for your replies. I'm aware of how to operate the clutch :) so I guess I shouldn't have to worry. My greatest concern was of course the torque which will increase from standard 250nm to 320nm a 30 odd percent increase. The extra power isn't meant to be used as slingshot-red light startups, but rather as a comfort when overtaking on highways. And if the clutch gets overwhelmed, I guess I'll have to upgrade it ;)
