Title: Standard clutch with a stage 1 map on an ed 30?
Post by: alfboden on March 11, 2013, 05:52:52 pm

As above does anyone run an edition 30 with a stage 1 map and standard clutch? If so how is it fairing?

Loads of people  :grin:

Some people have no issues, others have clutch slip - if not straight away, after a while.

Luck of the draw really, my GTI clutch slipped straight after the remap  :sad1:

Mine was fine stage 1... As soon as I went stage 2 it slipped...

I'm getting a new clutch next week and as I'm not going above stage 1 was hoping I could stick with standard?

You need to find out what torque the oem pressure plate will handle. If the torque on your animal is higher then you'll need an uprated clutch.

Mk.V GTI started in 2004. No need to find anything out. All data is already well known.
Clutch is specified at 350 Nm +10 % = 385 Nm. Same with ED30/Pirelli. If you run more
than this, you will need an uprated clutch, earlier or later.

BTW, you cannot specify a torque to a pressure plate, just for a pair of disc + pr. plate.

My stage 1 ED30 has a new OEM clutch & DMF - is the DMF ok to use with an uprated clutch long term when going 2+?

The aggression of the torque curve is also a factor, I have tuned many cars on the dyno that have had slipping clutches when requesting a specified amount of torque during mapping that have had the slip issue resolved by altering the ramp of the torque curve, but still requesting the same peak torque.

Most likely - yes.

Agree. A more aggressive curve will cause the DMF to hit to the stop. With a DMF I'd prefer a smooth torque curve.
