Slight clutch slip
« on: February 06, 2013, 10:53:45 am »
Hi folks! Looking for some advise regards to clutch slipping . Whilst drive home from Edinburgh this morning sitting in top gear just below 3000rpm I put the foot down to pass traffic and I'm getting a small amount of slip only for a few seconds the revs rise about 500 rpm then car pulls as normal again! This only happens in top gear at this rpm can't get the car do it in any other gear or speed!
Car is 2006 gti stage 1 46k

Change down then.

You are applying maximum torque to the gear with most resistance. No wonder it slips.  :happy2:

Changing down defo works but this seems to be a new issue as its never done it before in the 3yrs of ownership/mapped!

A healthy standard clutch should be able to take WOT from 3k in any gear without slippage on a Stage1 GTI.  Although it's not recommended as good practice all the time.  A medium throttle should be fine though.

An aggressively torquey map and a lot of low RPM WOT'ing will definitely reduce the amount of miles you can get out of it... you've had 3 staged years on it...

Cheers for the comments folks  :happy2:
My map is quite aggressive (giac) and over time I've maybe became rather lazy relying on the torque to do the work ! Ill see how long it lasts and take it from there  :driver:

Ahh sorry I forget to read posts properly! Do you get lots of wheel hop and gear stick shake if you floor it in first? I think I need some stronger mounts as its always wet where I live  :drool:

My GTI was slipping on day one after the remap. My Focus ST before also slipped with a remap. It does depend on the health of the clutch but I cant help thinking any mapped GTI manual will get clutch slip at some point, if not straight away.

The slip will only get worse. . . .  :sad1:

Says who? Do VW say that in their documentation somewhere?

Thought the standard clutch was rated at ~350lb/ft - if that's more like 300lb/ft then I can see why some of these aggressively torquey maps have issues.
Bluefin is much more restrained around 250lb/ft S1 and 270lb/ft S2... perhaps they realise the problem, where other tuners simply expect customers to swap out their clutches for an S1 map! :surprised:  Adding a whole lot more expense to a simple ECU flash!

A standard clutch should easily be able to handle a stage one map! As for the designers of them, they  surely wouldn't use a clutch that was rated to just above a standard cars output figures as that would mean a crappy lifespan on a standard car. There are enough stage 2+ cars that run no problem. Mine been one. I did a track day and full day drag strip all on standard clutch stage 2+ and no problems at 50k
