Very interested. but just wondering how much these effect daily driving with relation to clutch use as I already have a brass button clutch & wouldnt want to make gear changing much more of a hassle.

Cheers,

4340 is perhaps the highest grade high tensile steel that most machine shops can machine!!! THe japanese ones that are below 5 kgs are a totally different kettle of fish they are billet cast then machined (very expensive)... Also all you guys wanting to go below 5 kg have you thought of the effect on MAIN bearingS when doing this and not haveing the crank balanced; as you would in a rebuild.... Word of warning!! Going to light would be detramentle...

free bump!!!they sound good pity i have a tripple plate!!

nice price on the flywheel.

The comment about going below 5kg on a balanced flywheel causing any kind of damage to bearings is rubbish however. You should retract the statement for fear of scare mongering for business, a tactic I'm sure you are not advocating.

I'd like to point out that 6kg odd is still alot lighter than factory stock and for those who don't have $500+ to spend on a lighter unit it offers a cheap but, very significant performance increase.

the flywheels are CNC machined but are they also balanced at a significant rpm?

i want this to hurry up and go through as I have my new box ready to go in.

We need 4 more people for this to happen.

[Anquetil]

If you can't get 10 people, are we still able to get them even if its a bit more?

I will find out today how much we can get 6 for

I have added a picture of the flywheel.

Ok

We can buy 6 now for $375 each at the same price as before

The group buy will remain open to try and sell the other 4.

The company is getting 20 made at the moment and they will be ready in 2 weeks

I will PM all people who wanted one and arrange payment once they are ready to ship.

Hi, I am a definate for the GB on the light flywheeel. Can be contacted on 0414780869.

Thanks Ken

Awww noice!

Where do you live/work Darrin, I can drop the cash off?

[sky30]

What sort of performance gains are there from using one of these lighter flywheels?

How much quicker will the engine rev?? Im interested.

[rb20-calais]

Damn my bro is coming down from Brissie in 13 days, any chance they could be ready earlier or at least one?

Still get one but it would be really convienient this way

Sky30: It depends on who you listen to. From my understanding, after fitting the flywheel the following is true:

- Torque will decrease, thanks to less inertia , due to less mass on the moving flywheel.

- The engine will rev faster, thus generating exhaust gas more quickly, thus spooling up the turbo faster. (This is faster in time, not faster as in lower rpm point) Unknown exactly how faster it'll rev... depends on load and enviroment, etc.

I'm keen for one but i really need it sooner. Do you know if that's possible?

Looks like they will be ready by the end of this week or Monday next week

I will let everyone know when they are done.

[Sciby]

Woot! Darrin, I'll be down in Bris in 2 weeks, so might have to arrange a pickup from you.

[Guest Robo's]

Ive been Reading abit about these, apparently its like dropping the weight by about 100kg in first gear, so you could imagine the accelaration. It takes less effort to run. The motor will spin freer, but noticeably idle a little rougher if you go too light.

Theres a couple of good reads on the net on these. Do a search!!

[Sciby]

They're a wee bit of a trade off... lose a bit of torque down low, but who the hell cares because you're into the meaty power/torque zones faster, so it's all good.

If you really care about torque (as we all really should), do a 3L conversion or put some cams in.
