    Just had the flywheel cleaned, but think they got a little trigger happy. In this condition, would it destroy a clutch plate or would it just be a strong bite and then smooth out over time?

    I think it will tear the disk apart, the surface should be machined.

    Just to be on the safe side, i've just put the flywheel into a shop to have it skimmed (and lightened too :yum: ) should see the results in the next 2 days.

    Good idea, you dont want to waste time having to do it all again if you have problems

    Conversion done. Feels to rev so freely now. Bite point really low, but I may solve that by adjusting the pushrod length. Remap next me thinks. BIG thanks to Jason (voorhees) for his help over this weekend.

    So what clutch in the end did you actually use?

    And on the free revving side of things i wanted to weigh the standard set up when its out because according to the ECS weights on their site under the S4 conversion the standard set up weighs asmuch as my single/S2 set up when i weighed it...:(

    Used a 1Z Tdi clutch for the time being (as it was sachs and cheap) but can upgrade at a later date if needs be.

    Didnt weigh the two FWs, but at a guess the SMF felt about 1-2kg lighter than the DMF

    Hmm hopefully it is lighter then and ECS are wrong on the weights. I weighed my clutch/fly all bolted up together and it came in at 16.4kg`s (i think) and the ECS website lists exactly the same (without going and looking at the site)

    The setup i used (when bolted together) didnt feel anywhere near 16kg. Totalled, felt more like 10 ish, but i could be wrong. the test will be tomorrow, when i up the power, and see if the clutch is upto the job.

    I'd give the clutch some time to bed in before trashing it.

    I found the clutch to start bite very low, but required a fair amount of travel before properly hooking up when it was brand new, then after a few weeks the bite moved up a little and the travel from bite to fully engaged reduced, presumably as the two parts mated together.

    Well after the travelling today, I think the clutch should have bedded. (down to London, circa 70-90mph, around London, on to Woking and back up to the midlands 80+some mph) few hundred miles worth plus clutch use in stop start London traffic...

    stop start type driving is what you need really, ie slipping the clutch. 200miles on the motorway wont have done very much to bed it in.

    Hopefully be alright though, mine went onto a used unskimmed flywheel which had a slight ridge so maybe thats why it took longer.

    Well the cars running peak 14psi now, couple of WOT's in each gear and no signs of slippage. Seems happy enough though I'm going to take it easy for the rest of the week. :)
