Its just going to happen! So Im looking at the next clutch.

Im interested in the 6 paddle GB but I have a GTA clutch in the garage as a spare from my 156 GTA engined Racecar. Its done circa 1000 miles.

Diameter is the same (checked in my clutch book) but interested to know if anyone else has used it.

Ive just fitted a GtiRS (stage 3) and want to run 300-320.

Thanks

I use it.

I hit 486 Nm (358 lbs/ft) during last RR (1.7 bar). After that I turned down the boost level to 1.4-1.5 Bar (circa 440 Nm/324 lbs/ft) and have no problems at all. Almost the same feeling as OE clutch.

I used to have a gta clutch at 330bhp and it started slipping. I have a helix organic clutch now and have had no problems at 360Bhp/357LB/ft. GTA Probably on the edge of being adequate.

Thanks guys

GTA clutch circa £130 new, 6 paddle £250 dont know about helix organic.

Anyone got a link to the GTA clutch?, sounds like a good upgrade for those running a little more bhp & torque, and cheaper than the standard Valeo.....

Considering the GTA runs a similar to torque level to a standard 20vt, I don't see the point in using a GTA clutch, might as well use a normal clutch

the GTA clutch was reccomended as an 'upgrade' when run in combination with the walkers cover plates, but then your looking at £300+

Ninja

Not only the clutch plate matters, pressure plate also counts a lot into this equation.

What's the main difference between the Alfa GTA and Standard Valeo clutch? anyone?

I'm certain I read somewhere that the GTA clutch plate is of a slightly different material to the normal Valeo one. No idea whether it's true or not...

Ive emailed Valeo, lets see what they say

My friend got GTA clutch on his 400bhp Coupe and clutch works fine.

Need one very soon also to cope with 292ft/lbs so not HUGE
What price can be expected as a good deal on a helix organic?
The price of £250 above looks good for a paddle and a gta is cheap but not sure if its enough for 330 bhp alfatim on the long run sounds very similar to the std one.

i had a gta clutch.fine on a standard coupe.soon as u tweek,then a no go.only lasted 6000miles.bite the bullet and get a paddle 1! will save u money in the long run.talk to john at midland car services,did a great job on mine! running 309bhp and 300lbs tourqe.easly copes nows

Great looking car

Is it 402Nm in engine (crank) or on the wheels?

Spoke to Valeo Technical today.

Limited info but confirmed that the GTA clutch has higher clamping load @ 6500 wheras the Coupe 20VT is 6200. (This figure is written on the clutch cover)

He also mentioned that the friction material was diferent, but added that this may be because the GTA unit is more modern.

Wiating for a more comprehensive reply to an email, but he mentioned Im not the only person to have requested this info?

Don't believe the hype,

The GTA clutch is rubbish I have just fitted one to my coupe which I have returned to standard 220Bhp and its slipping after 300miles not impressed!!

Mind you I do use 102Ron petrol and decat which may make a slight difference

It seems after further investigation as Ninja mentioned its a combination of the GTA friction plate and a Walkers pressure plate which is a good upgrade.

Wish I had read a bit more before buying!!

I can't for the life of me remember where I read about the different material, but the person did say he had spoken to Valeo.

Anyway I'm off to go and check what's on my Cover I have upstairs.

The GTA clutch is not rubbish, I would suggest a faulty unit or a problem with your car. I have a GTA engined racecar and the same clutch has dealt with 265bhp FLAT OUT for 2 years, albeit on track at all times. Considering Easytrack do circa 50+ events a year, thats ok.

Best check out as at 220 bhp it should be no problem.

BTW it does this http://www.youtube.com/watch?v=vdmL7mhWPQc

:-)


Valeo rate the GTA clutch at 370nm btw (not sure what that is in lb/ft)

370nm = 272lb ft

Is that from your Valeo source?

Valeo told me some years back that the cover plate and bearing were the same part for the 20VT and the GTA!

The friction plate is different in that the friction material is marginally wider, and the springs are more compact.

As begbie said - there is no obvious difference to the standard 20VT clutch kit, it should be considered an alternative, not an upgrade.

For the record, there have been many cars with 300 lb-ft of torque over the years running the standard clutch for some time without problems.


Helix 3 piece organic clutch is £475.

Yes.

Valeo technical UK 01527 838300

Definitly clamping pressure is diferent and he said that from the info he had the material was diferent. Seems they may tell diferent people diferent things

Well I can only speak from my own experience of the GTA clutch but on my own perfectly running coupe it slips on overboost in 2nd, 3rd, 4th, 5th and 6th.

As soon as I tried my G-tec 1 chip it was undrivable.

The turbo and actuator are brand new and done under 500 miles the flywheel was skimmed prior to fitting, fitted a new EBV as well as old one was shot and health test last year before I was running 300Bhp on a 60trim T28 showed the engine was over 150Psi per cylinder.

So the car is fine fit your GTA clutch to yours and see how yours behaves.

I was only giving my experience as that is what you asked for in your first post.

Ian

Mine slipped aswell.
If you're going over 300hp forget it. And under 300 - why not the std one.

"Don't believe the hype"..

Could you ask them how much the standard 20vt clutch can hold?

Maybe you should add that you was using 1.6 bar and ca 450 Nm of torque

I have no figures, as you know. I only know I used Fleas mapping and GT28R. Anyway - it seems I'm not the only one with this problem..
The bottom line is - the std Fiat clutch holds torque/power better than the GTA. That's very clear to me!

How high boost pressure (or torque figures) have you used with GT28R and standard clutch?
