I'm sure people who have used one will realise this, and those that think a 5kg flywheel is good for the road will soon find out!
correct, i think you need to find a balance... too light and you may loose some drivability...

think grant means that if you go to light the idle is normally a big problem as you have less inertia to keep it smooth

that's what i meant i think the you might stall a bit more if the flywheel is too light... could be wrong though..
anybody know what the optimum weight is?

AS mentioned I have a lighter fly wheel and yerh there is the chance it can stall, but thats what the throttle pedal is for. Just buy one, its a good part of a tuning setup / package.
Standard flywheel machined down at a engine tuning / machining shop. Cant remember what figure was quoted for being removed, but was lighter when compared to a standard flywheel I had spare.
Mine is 8Kgs and i have no problems and i have an ON/OFF clutch With a clutch pedel like a brake pedel
I do use this a as a daly drive when the weather is half decent only to run it in

Wilky you have a email
My car comes out the factory with a flywheel lighter than that so its not really any suprise you have no issues

That flywheel is fine, the standard one is too heavy IMO and this just makes it normal.
My car is not a "daily driver" - I don't use it for work, and only really use it at the weekends. I am looking to build a quarter-mile -orientated set-up, while improving the weight-distribution and handling for occasional track use.
My old M16 GTi was cammed, so I am used to driving a car requiring throttle/clutch balancing - and this type of set-up doesn't bother me in my primary car...
The weight reduction will be part of an ongoing reduction/re-distribution program, with batt-to-boot done, a lighter flywheel, carbon fibre roof panels and bonnet, and the water reservoirs moved to boot - I think IRO 30kg will be (re)moved from the front end, vastly improving the handling over a standard T16 - hopefully resulting in handling similar to K-series coupe.
Looking forward to getting back to the UK and getting my car upgraded - will be sure to report back on the changes when the car is finished...
6kg???
Feckin hell Ryan - you sure?
That makes yours 6kg!
Lightest one I've ever done was over 8kg... That is currently in my Bubble and has NO RELUCTOR RING as it was turned off completely.
I can confirm that I am very happy with this purchase - and have had no problems with cutting out at junctions etc...
I think it will be necessary to increase the warm idle on a T4 however, as my coupe seems to drop to 600rpm +/-100, and I think this is a little too low...
Any questions about our flywheels (TTV Racing) please feel free to ask me.
Starter for ten:
- are they 'custom' or reworked originals?
- how much do they weigh?
- if you dynamically balance them, what's their inertia?
- how much?
Don't know if Bens about much, so I can at least answer the 1st couple...
1. They are machined from billet steel, not re-worked OE. I have a few pics of mine, and fitting it, but still waiting for b-band at home - next few days & I can get some pics up...
2. Its earlier in the thread - 5.3kg
Available in 2 or 4-gap.
I'm sure ben can answer the others when he's back...

Yeah I saw the mass, it's the inertia value I'm after.
Hi,
Dynamically balanced means they are measured on 2 planes instead of 1 it doesnt give you the moment of inertia.
They are cnc machined from billet steel so they are many times stronger than the std cast item and also provide a better surface to grip for your clutch friction plate.
I cant tell you the weight as i have sold out so none on the shelf to weigh for you, i may have told Dom the weight when i supplied his he may be able to remember.
We also offer an option for 7 1/4 or 5 1/2 race clutches
This is our T16 flywheel
I can supply forum users at a discounted rate so id could do this delivered within the uk for £220

Getting a bit worried now. I weighed mine the other day and it registered 6.5 KG. We will see.
