Is there any point in getting one of these on a lightly modded XE? (exhaust, induction and 4-1 maniifold) What are the benefits apart from its physically less weight to lug around, and could it make the car drive poorly around town etc?

Yo be gettin custom ones or machining the existing one?

Get one, motorbike revviness (well not quite) There's a limit to how much you can lighten a std cast one though.
Doesn't make piss all diffeent to "town" driving, only race clutches make lift difficult.

Hmmm, not got much on today, might go and chop a few mm off mine with the trusty angle grinder, can do it by eye

Actually, I might just de-flywheel the engine, problem solved. Not like it does anything

engine will have to rev harder to get up hills, since the flywheel loses some of its inertia properties when lightened.

could you imagine fitting one to a stock 1.2 8v and go up a hill at 70mph, you would fucking stop half way up

The gains a fly wheel gives you is a percentage equivalant weight loss, its a calculation based on car weight as standard etc, to put it bluntly 2KG's off a fly wheel on a adverage car will be like a 120kg weight loss in 1st 80kg weight loss in 2nd 35kg's in 3rd then its hardly noticed after this, the lighter fly wheel will be effected by clutch dragg allot more, the clutch will have a fine bite point, so will take gettin used too, only super light flys effect the idle, oh and a quickshift would be a good idea otherwise on gear change the revs will drop so quick you wil be out ya power band once the power is applied again

how much did this set you back & how much reduction did you have?

I know someone who works on metal so could get it done for the cost of a few pints down the lcoal

i fitted a light weight flywheel on my v6 vectra giving it a 10kg reduction in weight. certainly picks up alot quicker and is alot more economical!

XE's spin up rather easy so unless you have an LSD your going to be spinning up more from standing starts.

It was done when the engine was rebuilt, so was included in the labour. Not sure if it was machined evenly so the flywheel was balanced or anything - whether it makes a difference or not I dunno..

Have one on the Evo, didn't noticed any performance increase to be honest. Was fitted when I had my paddle clutch done.
