Yes I have done a search but couldnt find any definite answers.
So who has had their flywheel lightened and to what weight?
How low can you go? Have heard 5.5kgs but I think that is too low for a road car.
Oh only asking about a 16v abf engine
-
Actually I just found this - http://www.golfgtiforum.co.uk/index.php?topic=134237.0
But looking at those photos my "spare" flywheel dont look like that!
The toothed edge seems to be double that width!
-
What part number is on your flywheel?
-
Hotgolf (Mart) has just lightened and balanced mine to roughly 5.6 KG which he said is the norm when he
lightens them :cool:
-

Will look later
-
Best bet is, just speak to hotgolf and he will advise you the best. His on here too
-
What part number is on your flywheel?
Think this is it! - 037 105 273C
There are other numbers - GGG50 and /07057

Couple of pics of my spare flywheel

That's the same part number as mine; the latest ETKA doesn't recognise it but it is an ABF flywheel.
-
My ABF flywheel taken down to ~7kg, was fitted (and still is) to 20vT.

Did it not need balancing?

Panic over then!
Maybe I was looking at the one still on the diesel engine I have! :rolleyes:
:grin:

Martin (hotgolf) left a comment on my build thread the other day,
about halfway doen, ignore the forum numpty trying his hardest to be clever tho :rolleyes:

Interesting read Brad. (except for DH) :grin:
I'm certainly glad he makes the distinction between turbo and NA as they need to react differently.
Think I'll go for a conservative 6kgs.
More interested in making sure its balanced.
Very surprised he has gone so low as that is nearly half original weight.
-
Do you find you need to give it bit more revs to pull away? As there isn't so much of a mass to keep the engine turning?

I had mine down to ~6.2kilo and never noticed any cons, just pros :smiley:
Obviously a new clutch at the same time is good economy
-
Ive said before in another post in reguards to light weight flywheel. I had mine done from martin (hotgolf) and you will need to rev it more as you have less mass rotation so yes more revs but the car does fly through the rev range :evil:
-
One question does the lightened flywheel stop you from crawling like in a traffic jam i just leave it in say gear 2 with no accelerater pedal pressed and my revs will go down to 1000 would a lightened flywheel stall the engine in this scenerio
-

Not realy. As im always creaping when stuck in traffic. Only when you got to move from standstill you have to rev it just a tiny bit more
-
Ah so its only when the clutch bites you give it a bit more revs
-
Hmm maybe I should turn mine down a bit more.... 2.5kg off isn't as much as most people have taken off it seems. The livelier the better :evil:
-

Wouldnt go too low. Youtube flywheel fail and see how much damage it will cause :shocked:
-
I've machined mine to 7kg for now. Weighed in at 9.5 to start with. Will be a few weeks before I fit it anyway but I don't want to be underwhelmed with the difference when it goes on...

Same weight as mine, was a fair difference for me, although I was coming from a dual mass mk4 item.
However many mentioned the lighter pedal feel when swapping out a dual mass, but nobody mentioned any difference for Liveliness, which there certainly was in my case, so I guess it must have made a significant change.
I also noticed that coming off throttle, the engine brake was a lot stronger, less rotational force I guess. This could be classed as a downside.
-
More engine breaking the better :evil:

Having now seen pics of my original and spike's turned down one (its in "what have you done to your Golf today") where the metal is taken away from should have no effect on the clutch bearing area.
I would suggest that a flywheel failure is more likely to do with imbalance or a faulty fitted clutch.
-
Received my new lightened and balanced flywheel today, it weighs exactly 7kg. Now to raise some cash for a Sachs Vr6 clutch kit and fitting...
-
Taking mine to be done this weekend
-
If anyone is going to turn down their own flywheel, it's best to make sure it's balanced, as per hotgolf or you could knock something out on your bottom end. Possibly.
-
I would be more worried about people deciding to fire up their work lathe and remove material without knowing what they are doing.
It's just a shattered flywheel, blown bellhousing and potential serious accident away. Not good.
-
I dont think thats the hard bit. Any decent engineer who uses a lathe should know about sharp edges, burrs etc that can cause stress fractures and weaknesses in a material

Thats why I took your advice and had it done by Hotgolf. :cool:
-
Fortunately I'm one of the ones that knows what I'm doing :grin:

Agreed!
and Thanks :afro:

Having run the ABF flywheel around 5.5-5.6kg for a few years, I can't see a downside & the response is everything.
Interesting is when say a Mk2 is fitted with an ABF, but retains the 020 box, the flywheel can go down to something in the 3kg range, and still it is hard to see a downside!
Definately contributes towards waking the powertrain up
-
Most of the time people want performance improvements but want the rest to stay the same. There is going to be a slight momentum penalty, but all it takes is better throttle and clutch control.
The Missus mentioned to me that my car needed more revs to pull away than the other car, but i've never heard complaints about overtaking ability. :grin:
-
Think I'll be more than happy with my 6.1 kgs then!
-
looks like alot of you guys have done this now. how worth it is it doing?? im guessing its good as so many have it done.
is it time i buy a spare and get it sent off lol?

Yes! :grin:
-
Only one way and that's Mr Hotgolf's way :cool:
-
Or mine :whistle:
-
Yes and yours :cool: I will be in touch when I get my throttle body if you could still do it for me :cool:
-
Definitely, apologies for the delay in getting back to you. I will have time to take my throttle body off this weekend and measure it up to get a feel for the job before taking it on. Drop me a PM when you're ready :cool:
-
Cheers my friend :cool:
-
^ spike did a top job on my flywheel! :wink:
-
Cheers Len, I'm really looking forward to seeing this ABF come together :evil:
-
Any pics?
-
Of the flywheel?
-
Here's a picture of mine I did a couple of weeks ago. I didn't take a finished picture of Len's before handing it over but I'm sure he can put one up.

-
Whats the weight of that ? doesn't look like much has been taken off.
-
Down to 7kg. I took Len's to 6.1 :smiley:
-
Ah, Should have took off more :wink:
-
I managed to buy a brand new 7kg one for basically the same cost as a refinished one, just got to get around to getting the bugger in place now. I know i could have got a lighter one but really didn't want to make my car any more difficult for the biatch indoors to drive.
-
I've got a 5.5kg one to go on my vr6
-
Down to 7kg. I took Len's to 6.1 :smiley:
And I always have another flywheel if I feel that 6.1 could be lighter!
-
anyone got a spare original one they wanna sell me??? :smiley:
-
I will have a spare ABF one for sale in a couple of weeks :cool:
-
Ah, Should have took off more :wink:
Yeah considering everyone's having theirs lighter, I might rework mine down to 6.0/6.1kg. Still doesn't mean I'll have the chance to fit it any time soon :laugh:
-
I think they can go to ~5.5kg.
I'm sure mines around that figure.
-
Yep Hotgolf lightened mine to 5.6KG which he says is the norm when he lightens them :cool:
-
Was there much loss of driveability? It's all well fitting a new clutch with a lightened flywheel but not if you'll burn it out pulling away :laugh:
-
I have not fitted it yet. Everybody who has had their's done by him on the club gti forum is well pleased so I
guess not. As long as I get the best performance. I don't mind changing the clutch in a couple of years if it
does. Not that expensive to do :smiley:
-
I win??

-
But that's not an ABF flywheel :tongue:
-
020?
-
That's an alloy flywheel non? has a steel face insert thats screwed on ,very light and not cheap,would love one of these! seen them at 4kg for the 1.8t but was 500 euros :laugh:
-

No loss of driveabilty. Tried and tested many times over
-
Damn, you guys caught me out.
6speed fidanza flywheel. and 5puk paddle clutch to go with it :D
