Scraping Sound When Pulling Away In First Gear/reverse

Hi, I spent a few minutes after work making this video: -


https://vid.me/SsST (very prominent)

https://vid.me/TXKc (pulling off a little more quickly)


It's reproducing an issue that I'm having with my car right now which sounds horrible.


Basically, whenever I pull away in first, it usually (more so when pulling away very very gently), makes that horrible scraping sound. That's a particularly bad sounding one as I attempted about 20 times to get the worst sound one that it makes and tried to prolong it.


The clutch is a triple plate clutch greddy and has no problem holding a lot of power, as you would imagine a clutch like this could, and can launch without problems just fine. I hardly ever launch it but I did a few lately just to test for any issues and it was fine.


I spoke to one of the guys who's worked on my car before and I was told that it was probably just an unsprung clutch and that the sound was not a problem, as long as I could put up with how horrible it sounds. I'm beginning to think it's a bit more than that though and possibly a throw out bearing? The clutch behaves like most triple plates and makes the funny rattling sound when the pedal is pressed in.. that's cool, I actually like that noise. I think it's getting worse though and I need to take it somewhere but I would love to know what you guys think!

My car makes the same sound, been told its probably a button clutch. Had the car for 3yrs no issues with the clutch other than that god awful sound. Not sure what clutch is in it though. It's stood up to a decent beating here and there too so dont think theres anything wrong. I'd be interested to hear what more knowledgeable people think though. Good luck.

Edit: Button clutches don't like to be rode whereas a normal clutch you can ride it a fair bit (still shouldn't but you can). I guess that's why on faster take offs they don't make the sound as much.

Ah right, so it's just because I've got a ridiculous clutch.. that's ok then.

It definitely only occurs when slipping the clutch; if I launch or pull of spiritedly, it's like a dream!

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      That dirty voltage drop is the culprit I suspect

      It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
