thanks lads, its got me thinking now lol , but surely the more torque will kill the clutch quicker ??
Yeah, it will. Mine started slipping when I had a full BCS fitted on Stage 1 R-Tech (k03). This was only at around 320lb/ft peak at the time.
It's not a solid rule for every car though - there are quite a few tuned ed30s on here on standard clutches. So you might be alright. But there's just as much chance it'll kill the clutch. I bit the bullet and went for a Helix Organic clutch with new OEM flywheel. Good for 400lb/ft. It stung a bit, as I wasn't expecting the outlay, but now I'm in a good position to run some decent boost.
Put it this way, if you're wanting to go past 300lb/ft or so, ie past Stage 1, it would be wise to have the funds backing you up just in case the clutch goes. I wouldn't say you'd be unlucky if it did, more that it's highly likely.
The DSG boys don't have this problem, up to 400 odd lb/ft anyway. But then their uprated clutch packs get really expensive!
You said before that your Cossie is the real toy, so I'd personally be inclined to chase power with that. Plus, there's only so much power you can actually get to the road in a mk5 GTI. Mine will spin up in 3rd if it's too cold or even slightly damp on the roads. Which is half the bloody year in this country. Although it's damn good fun when it does hook up and you can get 350lb/ft down!
