Xtreme Stage 1 kit ordered and hopefully it will solve all my issues.

On that note, does anyone know what the OEM clutch assembly is rated for power/torque-wise? I saw that Xtreme says theirs is rated to 600nm but that's not a whole lot more than what people are already running on the stock units. Of course there's the benefit of the lighter rotating mass that the Xtreme clutch/flywheel set offers, but past that it doesn't really seem like much of an upgrade in terms of power-holding capacity.

I think I've read somewhere that Hyundai is pushing around 300-400PS in internal testing with stock gearbox, but I don't know about the maximum possible torque. But there should be more than enough overhead.

420bhp through original drivetrain going round the N ring.

Wonder what turbo was used for that setup, I doubt the stock TD04 would be able to push out that much power.

Or do you mean it was 100% stock as they come when you buy them? If that's the case that's pretty impressive since at 420bhp these engines would be putting out 600nm+ I would imagine

It's a test vehicle under the premise of "how much power car we get from this car?" Basically a project run by the engineers to test the limits

Moved your posts in this thread. Please search the forums before asking something or posting, there's a very good chance that the thread already exists. Going off-topic in the wrong threads in complex long technical discussions is not something that is wanted to be honest. :)

Noted, sorry about that. Thanks for moving to the right section!

I am not worried about oem disc (should be also organic) and basket - they should last 500Nm-s but not sure about release bearing and 2-mass fw. My car has 6000km mileage - around 2500km on highway, 1000km on track and the rest in traffic jams. Fw started to make noise on 2500km and release bearing on 4500km.

Oh, boy... Sorry, but these types of flaky issues should not be happening with that few of miles/kilometers on a “performance” car.

1000 kms on a track flat out is NOT a few miles....... 2500kms in stop start traffic jams, also very hard on the clutch. I hate driving this car in bad traffic jams. I absolutely love the car, and I find every excuse to drive it rather than my work vehicle, but on days I know the traffic will be bad, I take the work car, it has a B18C in it, with an ultra short JDM LSD 4.7 final drive gearbox. It will idle along at about 1 km/h in first gear (unlike the N). Admittedly the gearbox is so short, it sits on nearly 4000 rpm at 100km/h in 5th. Needs at least 2 more gears!

Hyundai like all other manufacturers build these "performance" cars for the road, not normally driven flat out the length of the Bathurst race! Someone will offer an extra heavy duty clutch for the N soon enough to keep TarmoT happy!
 
@Corsa59
Respectfully disagree. If they’re going to claim the car can be tracked, they should’ve tested it as such to find deficiencies. The VT1 gearbox rarely has any noise issues and some have used it to do many HPDEs & weekly autocross events during the warm months, whilst still commuting daily.

That's actually the one he ordered... And the one I was talking about being disappointed with it's holding capacity of 600NM at the flywheel (I assume). That's likely less than what the stock clutch offers in terms of holding capacity.

I'll be waiting for a more competent clutch kit to surface before jumping ship and dumping the heavy dual-mass flywheel and clutch set (mostly cause my car is still fine, mind you I haven't tracked it yet).

1000KM on track here is about 2-3 full days worth (10:00-17:00) with stopping for breaks and letting the car cool down between laps adequately. That's really not that much, and the stock components should NOT be giving out that quickly.

My tired 175k KM M3 clutch held up better than that at 400whp. I personally had 2 track days on it and there were no issues at all. Considering the N was made by the same person I would expect the quality to be at least par with that.

^Bingo. I neither want to have to dig into the gearbox early on nor keep taking it to the dealer. Guess I’ll not do any major upgrades straight away and just focus on foundational mods until more is known. Perhaps the VN has had gearbox revisions. Wishful thinking.

If you will scroll that thread up littlebit, you can see that I bought it last week. But there are some problems still with that kit ( single mass fw is making bad noise and clutch peddal is very light ). So they asked me to wait 3 more weeks and promised that they will send me upgraded product.
That kit costs almost 1700€ but Xtreme is famous of his very good release bearing and flywheels. I can ask dealer to replace my bearing and dual-mass flywheel but I am pretty sure that final result will be the same. Anyway I have 8 Time Attack events this season + Eurotrip ( racing circuits all over the Europe) on plans this year, so everything must be ready for adventures.

Is it making a screeching noise during engagement?

Curious to see the upgraded stuff they send you, along with specs if they provide them.
