how loud should flywheel chatter be ?

[ceedubya]

i have just fitted this set up into my o2m 1.8t =

is the chatter normally quite loud when you back off the revs while in neutral standing still ?

In neutral with foot off clutch it will be noisy.

thats good to hear i will try it with clutch in

 

[pj1985]

When you put your foot on the clutch the noise should go away

just been out and tried it and your rightcheers

it revs up much quicker now too, much more of a difference to when i fitted a lightened flywheel to my mk1 golf gti

do they drive much different out on the road ? mine wont be on road for a while

If its New it will get slight quiter but only abit when its run in..

Mine did

i have the helix set up and the noise is inconsisistent,sometimes it's really noisey then it can be really quiet

There seems to be a sweet point where these don't make any noise.
I can get this by pumping the clutch

I find if you let out the clutch slowly its not loud but let it out quick and its noisy (at idle)

I thought a lighter flywheel would make the car decelerate much quicker but I seem to have no engine braking sometimes! But then it could be my r32 TB i think sometimes it doesnt shut as it should.

:if i come off the throttle approaching a junction, soon as i depress the clutch to grab 1st they drop and rise,very annoying.only started to happen since going r32?

Sorry caney I didnt understand, do u mean the revs drop and rise or noise?

revs mate.

Oic, well no my revs are the same in that kind of situation, but half throttle boosting is annoying for me, if you start to build up boost on half or even full throttle say over 1bar, if u back off just slightly so your still on some boost the car will judder abit, I can tell the TB is opening and closing that little bit but makes the car engine respond so much as its much more air flow vs standard 1.8t tb..

which part of the set up actually makes the noise ?

Flywheel!
The lighter the flywheel the louder it will be until u put the clutch in.

I think mine has helped the car rev up quicker, I guess your running just the alternator from your crank so should all help!

 

[pj1985]

Its not the flywheel that makes the noise its the lesser weight of the flywheel that lets the input shaft chatter which is what you can hear.

I stand corrected

 

[ceedubya]

cheers, learn something new everyday

if you hear a flywheel rattle its bad news as its falling off. (can happen!)

as siad, rattle is combination of no dual mass to isolate noise and input shaft and release bearings rattling a bit

makes you wonder why the previous generation of cars which came with single mass as std, did'nt rattle like these do. dual mass flywheels added to compensate for a not so well balance engine perhaps?? accounts money saving @ VAG?
