Lighten flywheel.

[mrzed07]

Can anyone tell me if fitting a lighten flywheel to my 2.6 v6 vectra will damage the clutch or any other associated parts. Will the pro's outway the con's??

[Evoluzione]

No it won't damage it, it will just make it harder to drive with a 0.00000000001% performance advantage.

I recommend another car sir.....silver ones are toooooooo slow

Why do you want to lighten it?

It will give you a freer revving engine and will aid acceleration in the lower gears. The effect lessens as the gearing goes up, with a 1:1 overall gearing the engine thinks the car will be lighter by the amount removed from the flywheel. With a total gearing of 10:1, as you may get in first gear, the engine sees the car as being 10 times lighter than the removed weight. So the effect will depend upon how much you remove. This is, as always, balanced by a lumpier idle and it may alter how you change gear as the engine will rev up and down a bit quicker.

Top speed is academic, it's acceleration I'm looking to improve. I believe the standard fly-wheel is a massive 15kg (?), the lighten one is 9kg. Having said that, it may be time to move it on. Spongy is right, some guy on a Ribble push bike took me at a junctions this afternoon!!!!!!!!

Don't bother! It's a huge amount of work for negligible benefit, and will decrease drivability and smoothness.

speaking from one chutney ferret to another i would take the above advice.have a good look on here my little pickled egg there are some nice motors up for grabs at the mo, or invest in some lycra and a ribble

I've seen good results with K11 micra engines, but they are much lighter revvier engines with less torque. All lightening the flywheel does is transfer most of the torque used to propel the rotational mass of the flywheel to the wheels. It doesn't give you more torque or horsepower, and it doesn't change your top speed (that's for your gearbox and diff setup to decide), but it lets more torque go to the wheels, and as torque is rotational force, it means the engine revs easier and the car might accelerate a bit quicker.

I won't look good in lycra and a helmet that looks like 1/2lb of sauage. May be time to change the car then.................
