ORC clutch with flywheel

**TypeG** · 17-12-2006 05:06 PM

Anyone got this kit in K series or even B series? I got a slient model and I do notice some noise when i pressed into the clutch which I am expected from what ppl said but I do notice some other noise when i drive till a certain speed and then take off my foot on acc, the car got like some spinning sound and the loudness depends on how fast i am expecially down the hill. Sound like something is spinning and the noise will gone when i put my gear into N. Is there any problem with the installation?

hey mate

im experiencing the same situation, but i got an exedy organic clutch and a toda flywheel

Its kind like a buzzing whining sound that is apparent when you get off the gas when you slowing down correct? its kinda like a gearbox whine but not as loud.

I noticed this when i went to wakefield last month.

Last night i was coming home and it was quiet so i decided to do some testing...

when i suddenly get off the gas, regardless of what gear or speed, the buzzing spinning whining sound is there, and its again prevalent when i get on the gas rough, as in stomp on it rather than feathering it in...

sounds kinda like a racecar does if you know what i mean.

Does what im explaining make sense to you man, because it sounds the same, and no one can confirm WHY its happening, but i know theres a coupla other people out there experiencing the same problem

yeah mate... it is quite similar as the sound went away once i step on the acc again. it is totally not loud.... only when i got music off, window close and fan to lowest speed...... yeah try to slow down from a high speed and the noise start to get quiter and the sound is gone when it is in certain low speed.........

anyone got the same problem?

my exedy clutch makes the same noise as described by both of you.

ALN also has the same noise on his euro i believe.

I think with the extra springs and the additional vibrations the flywheel transfers you're hearing the springs rattle around slightly... I've monitred mine now for 10,000km or so and there's been no problems at all associated with this noise

Chris F, so its not a rattling, its a buzzing whiney sound right?

**Chris_F** · 17-12-2006 06:41 PM

nah, it's not a rattling sound, more off a buzzy wine with a slightly scratchy quality yea? I notice it when engine braking (its not a one off sound but consistent)

u got it mate

im glad im not alone, gearbox oil is fine and all that, u thought it might be the intake allowing more sound out but i always figured it had something to do with the new clutch and fly

thanks bro

no worries man, trust me i was freaking out a bit when i first started noticing the noise as well. I also checked my gearbox oil and it was very clean so that put to rest concerns that something was up with the tranny.

Shouldn't be anything to worry about, like any aftermarket part extra performance normally comes with a bit of extra noise

thx chris for verifying
somehow i am really worry about mod in the gearbox

Nah ppl, that noise is fine. I have the same clutch, although the non-silent model in a different car, also makes that burring noise on acceleration. The aftermarket clutches are meant to make that noise so its fine. Nothing to worry about.
