Sourcing 130i Flywheel
Discussion
Having trouble getting hold of one and wasn't sure if PH would have any suggestions?
Tried all the usual suspects (ECP, GSF, Googled it etc) but it seems they are out of production at the moment.
£250-£350 seems to be the going rate if anyone had them in stock.
Local BMW quoted me £890 just for the part so would like to avoid that if possible!

Yeah as far as I know its the same across all the 2.5 and 3.0 engines of the same vintage.
The ebay ones come in a package with the clutch which I already have, and they are charging £400+ for the flywheel going by what I paid for the clutch, should have made it clearer I was being really tight!

I think TTV Racing might do lightweight flywheels but if you don't want to spend much they might not be any good.
I would love one of their single mass jobbies (at least I think its a single mass rather than DM) but can't find anyone else using them! or any single mass stuff as far as I know? Although I think they offer a "road" and a "race" version so must be fairly well tested. Can't see them now, but I think I've seen prices before, will give them a call.Can find some old reports of Birds trying out a single mass setup, but I don't think anything came from it? Had gone off the idea but will have to look back into it, thanks for the reminder!
TBH the DMF and electronic throttle setup just feels rubbish to me, so lumbering and heavy, although getting used to it slowly. Would pay the money if it was a trusted setup!

Presumably all N52-engined BMs use the same one (I've got a Z4 Coupe with that engine so that is a bit worrying).
Yeah gonna look more into the single mass option, good thinking!Presumably all N52-engined BMs use the same one (I've got a Z4 Coupe with that engine so that is a bit worrying).
As far as I know its the same for all 2.5 and 3.0 N52s. The guy I spoke to said they are back in stock soon so doubt its a major worry!

I wonder why BMW went to the trouble and cost of engineering a dual mass flywheel, when you don't really need one?
A few reasons including:-Smoothening out the drivetrain ; helps people who change gear clumsily, and takes the strain the clutch springs max out at.
-Protecting the gearbox, but this is more of a diesel problem
-Quietness as it is a form of mass damper. Again, this is more evident with diesels.
A lightweight flywheel can be a mixed blessing. A friend had one in a 200SX S14a and was a 'manual' man. He hated it. It made town driving awkward. Unless you have experience of such items it is always academic discussing it on the forums despite the marketing blurb.

They certainly have their pros an cons. I have two Vr6s one has a lightened/balanced flywheel the other a factory standard (both single mass) I find the effect on deceleration more noticeable, with the lightened flywheel you lose momentum quicker however on acceleration and quick downshifts the extra response from the engine is well worth it. In the OP's position I'd maybe look at selling your existing clutch kit and buying a clutch & single mass flywheel conversion kit. like this https://www.onlinecarparts.co.uk/valeo-7696514.htm... **
might not be the exact one for your 130i but you get the idea.

Just a thought, but you still have the Clutch Delay Valve in place? If so, get it out as soon as you can - it's cr*p! My Z4 doesn't have one, and after a service this week my E46 doesn't either - it has transformed the car!

I'd give Birds a call as see what they say. They always seem very happy to chat stuff through without ever trying the hard sell - in my experience, anyway. SebringMan said:

Clutch friction plates used in dual mass flywheel application don't have torsion springs.That is the job of the DMF.
OEMs go to a lot of effort in engineering the drivetrain of cars, with parameters which are better understood by them than the aftermarket single mass flywheel sellers.
Thankyou for all the replies. 
Really can't find many people using single mass stuff on these engines, and I'm a massive sheep when it comes to modifying cars so think I have bottled it!
This is my daily at the moment but plan to go mad with it one day, will save it for then!
Now to just wait it out till the new year and see what they decide to charge for them once they're back in stock!
Thanks

Ah ha yes of course!My Z4 doesn't have one, and after a service this week my E46 doesn't either - it has transformed the car!
I really don't know if it has been done, previous owners have tracked the car and modded it pretty seriously, so figured it must have been done.
But, at first the gear change/clutch really did feel absolutely terrible, not sure if I'm just getting used to it now! lol
I got a new valve but haven't got round to fitting it yet.

Bin the valve. If the car has been tracked there is a chance it has gone. It's not the hardest valve to remove I really don't know if it has been done, previous owners have tracked the car and modded it pretty seriously, so figured it must have been done.

. You could also fit a braided brake line while you are there.I'll be honest though. My current Merc with the undesirable manual 'box is a far better shifter than my 323i ever was and that's saying something. The W124 is no spring chicken either at 187k.
I've owned both E46 320d and E90 330i, both presumably with CDVs fitted. Not that I find it an issue and I'm trying to find a problem with the clutch action, but it all seems to work fine for me. In town, when pottering around on A and B roads or when pressing on, I really don't have an issue with how the clutch operates. It must be a skill thing, or lack there of

It's when you want a really responsive clutch, and it means you can't because of the delay valve. Gassing Station | BMW General | Top of Page | What's New | My Stuff
