MiniPit Unregistered M	Hi guys I've just bought a complete clutch kit of ALFA 147 GTA for my 20V turbo. I bought it because you said me it is plug'n'play on our 20VT. But someone tell me the 20VT clutch is more resistant than the GTA clutch He tells me that the Fiat clutch can support more torque! I just want you to put me at rest. Are we wrong when we say that the GTA clutch is better than the Fiat clutch? I hope i haven't bought it for nothing Last edited by MiniPit; 11/09/2008 18:29.

Ok TurboJ So if the friction disc of the GTA is bigger it will accept more torque than the OE clutch I don't understand why the guy i meet told me the Fiat is better! Maybe a jealous person

MiniPit Unregistered M	Thanks guys In France the price of the GTA is smaller than the price of the Fiat clutch So : better price and better grip! That's a good deal Happy to know i've made the good choice

I care... because of the mod i'm going to do in the next weeks Big Hybrid T28 is coming from England (stock size for the turbine, trim 64 for the compressor... i know this is experimental... i hope it will be fine ;)) FMIC is ready to be on my coop too I've heard that standard clutch can support 320/330 hp! Hope that's right because i want this power

Even with a hybrid turbo, the standard and GTA clutches will do the job sufficiently well. Youre probably only gonna get 250-270 lb/ft of torque with that sort of mods anyway.

Yes increased clamping force increases torque rating but so does the surface area of the friction disc since both covers are the same only the surface area matters. The GTA disc is bigger than the coupe one.

Tu sais que delta il est partout p.s. sorry boys, but me and minipit know eachother, altough he diden't realise before I've tried all of them and my conslusion i make is: - stock clutch: 400Nm of peak torque ok but fast wear rate. - Walkers organic : 400Nm max torque as well but lasts longer - Helix: really good stuff but haven't been able to finsih one. It does accepts 400Nm sustained torque for sure. Nobody ever metions skimming the flywheel is primordial on a new clutch.
