I have just purchased a lightweight flywheel for the VX turbo from TTV. The flywheel # 0643 to be used with the 7.25" clutch is now at the weight of only 2.6Kg. Previously sold at 3.6Kg. I have not found a lighter one, Standard unit is "about" 9.6Kg. This should have a noticable effect. The cost including p&p and VAT was £285.00p Should anyone be interested. Regards. Korkey.

I had one of their supalite ones, but could not get the right sized clutch , so they exchanged it for me

weight of only 2.6Kg.

Jesus. That's going to be hard work crawling along in traffic.

There is a school of thought, going away from the topic slightly, that the best vx of all, is a standard NA with a lightened fly wheel and that's it. Maybe they aren't completely wrong.

Ah, that's a different school of thought which is very very wrong

[Thealastair34]

enjoy getting that moving! i have a similar weight flywheel with a ap unsprung plate clutch and its horrific feels like there is 60bhp in letting the clutch out its that harsh!

but then I am not really the best person to speak to about minor tweaks

[JG]

Mine is still standard thankfully

[techieboy]

Talking of schools of thought and lightweight flywheels. What's the verdict on getting an OEM steel flywheel lightened (within suitable limits, whatever they are)? Good, bad or indifferent? I see some people say it's the best way as they're made stronger in the first place. Then I see others saying a lightweight flywheel machined from a billet of steel or aluminium is better. Then I see people saying if the flywheel has separate ring gear to never mix that with a different type of metal, due to differing thermal expansion.

I have the OEM flywheel machined to about 5kg (I think). And statically balanced. It's fine on mine. But I haven't been able to compare it to any other lightened flywheel.

[vocky]

depends who you talk to, personally I think TTV make damn good lightened flywheels from billet steel and I would never fit a lightened factory flywheel or aluminium flywheel to my own car

[JG]

I must admit, the SC VX does really really need some weight shifting from the flywheel, so i'd be interested in the answer too.

I've got Courtenay's lightweight flywheel (4.2kg) in mine James. Definitely makes a difference. Usually good but I often curse it when pulling away in town and having to give it more revs than a standard one, to get some momentum. With the associated feeling that everyone is now looking at me as if I'm about to go wheelspinning off down the road.

I thought the ttv flywheel was the one Courtney's sell? If this isn't the case what the difference?

depends which engine you are talking about, the 2.2 flywheel courtenay sell is two piece (flywheel and ring gear) and the TTV version is a single piece billet steel item

that is because you also have the 'balancer delete', you should try the 'balancer delete' deleted version

WTF is that?

WIll it work on the Saab (no of course it won't, wrong bloody holes )

electric water pump, so no balancer chain

vectra B V6 or C20LET flywheel fits the saab B207 and F23 box set up

Hi Rich, how come you are going for a 7.5 inch clutch system? Lighening the rotating mass does make it a little pesky in traffic, but does also make the engine rev up considerably more snappily, which I am prretty sure you will prefer. Modern cars have heavier and heavier flywheels added to them fo emissions reaons, so the manufacturers can lower the idle RPM. I've heard that things like the Calibra V6 engine had masssive flywheel just to pass Californian emissions law (where the engine was used in some other US car), yet the same flywheel was realeased in Europe leading to a very lazy engine.
