Well ive just had this fitted and i know theres a metallic sound on cars with these fitted? The thing is mine seems quite loud between 1200rpm and maybe 3000rpm then im ot sure if it goes away or just drowned out by the exhaust noise.

Has anyone with this fitted got a link or video with the noise to hear? I know a video wont pick the perfect sound up but worth a try.

Oh and the clutch grips very well, no more slipping

Ive been advised that these are only rated up to around 350 ft/lb so im going for the RS clutch and flywheel!


I
hope not as i think mine may be more than that... This could be an expensive mistake considering the RS clutch and flywheel is cheaper

I have the helix and i use thin gear box oil and the flywheel is where most of the noise you described comes from. If you want it to be more quiet, use slightly thicker oil

Dont bother spending more money on another clutch. If you have the helix organic it is more than enough to handle the power most people put out.

Its the actual torque curve on your maps you want to look at. If it was smooth with no spikes you definitely DO NOT need anything with a harder material.

....bare in mind the harder clutch you get, the harder it will be on your driveshafts and gearbox.

Id rather burn out clutches than rebuild my box again...and ive done many many launches with the helix, the progressive feel is great! It is more than enough to cope with the power i am putting out.

Thanks
that gives me some confidence. So a rolling road may be in order to see how the torque curve is, at worst a change of mapping to prevent any damage. Cheers.

hey Lee, as maniac said noise is nothing to worry about, its what is called gear rattle. It is most pronounced when gearbox is hot, in high gear and below 3000rpm. Most people get used to it and some actually enjoy it. Noise aside helix organic clutch is the smoothest there is for the ST and i'm sure you'd soone appreciate how much abuse can it take


I got your message when i was at TOTD, my car made a bit of torque and the graph is as smooth as baby's bottom thanks to helix clutch.

The noise is normal - (is is normally damped out by the duel mass) - it should not get any worse.

The Helix's are rated at 316lbft for the organic and 372lbft for the cerametallic paddle type - however I am sure this just a case of Helix being cautious and covering there backs.

We have not seen any problems with the helix to date with cars running much greater torque than the quoted max.

Thanks for the info guys, thats my mind now at rest
nowt to worry about!

Oh i think the starter motor is on its way out as it makes some noise on start up
could this be a related noise i need to get used to?

That is not normal - I would get that checked out just in case it has not been bolted in correctly.

try starting the engine with clutch pedal depressed, helix is also noisy at idle
I bet you still hearing the clutch.

as vlad said when the car is on you shouldnt be able to hear the noise when clutch is depressed at all.

Old thread gents.

What is the rating on the RS clutch. I've got a RS clutch on order. But for about 50 quid more I could 'upgrade' to the helix organic clutch (rated at 420ft/lb) or a helix 5 paddle (387ft/lb)

Would either one of these helix units be capable of handling a possible RS turbo upgrade?

Ps. Smf noises aren't a problem, drive ability is (which is why I'm swaying to the organic disc type)

The Helix is heavier duty than an RS clutch, and a lot heavier on your leg too. I've driven one on an RS turbo converted ST, handles it easy.

What about the clutch Don Kalmar is selling?

I have the S60R clutch with Don's lightened SMF and it is noisier than a Helix kit.

heaviness on the leg isn't much of an issue for me. I'm just worried about the clutch being like 'a switch' whereby its either on or off.
My car is currently 330ft/lb and i hope to upgrade to RS turbo at some point this year.

I haven't been able to get onto Don's website recently (dont know whats going on there) but the helix clutch is very competitively priced for trade

Helix organic is heavy but progressive, I couldn't live with it's leg weight as I have dodgy knees but it did drive well. Not as initially grabby as RS clutch I think.

I just tried Don's site, no go for me either.
