Need to know where to take the material from on the flywheel to lighten it???
What weight should it be lightened to, was thinking around 10kg

Thanks

I'd give it to an experienced machine shop to do - an exploding flywheel will exit the casing, thru' the tunnel and chop your feet off at the ankles...ouch

Given that, the place that did mine made it thinner all over and then removed a bit more from outer edge. I wanted 7.5kg, they said forget about it and made it just under 8. Original on my00 is 11.5.

i am getting an experienced shop to do it but they have never done one for a scooby before!

done plenty other ones though.

Are there noticeable improvements from this? I guess you get quicker throttle response and revs would drop off faster when you take your foot off the loud pedal. Does it make for a better drive?

Hi,

had my flywheel replaced with an STI lightweight measuring ~ 5.5Kg, initially needed some getting used to mostly in city stop and go traffic, no big deal really, and you soon adapt to it. No adverse effects so far (30000 miles) and personally I think it's one of those really worthy mods. Very happy revving higher up.

With the original it's like going to work on Monday, but with the lighter one it's Friday everyday. Sorry for this obscure analogy but that's the way it feels to me. :P

had mine from 11.4kgs standard, down to 8.4kgs lightened.

have some piccies on disc if you want me to mail them to you. you can then see where the material is removed from.

I would say sod it.

Leave the standard one alone and get yourself a billet lightened flywheel from mark aigin.

At least if its billet you will know it will not be cracking and exploding in a hurry, plus it will be better suited to coping with the enormous heat generated by the clutch.

thanks guys

hmm, thats funny. as when talking to mark aigin at elvington in august, it was he who told me not to waste my money on a billet one, and to lighten the standard one, as you wont gain much, and the standard one will do the job just fine.
and we were talking about modded engines, not standard.

i agree that when talking about VERY powerful engines, then yes, billet would be ideal.

however, as with everything, it all comes down to what budget you have available.

I've got a billet flywheel courtesy of Mark.

I got a clutch off him and talked myself into a lightened flywheel too

Didn't really think i'd notice any change but it deffinately spins up quicker and feels a lot more 'ready to go' when your on half throttle

rob, yhm mate

Ian,

Yes I did say that, but it also needs to be taken in context.

If people have a "relatively" standard engine, or on a budget, then lightening the stock F/W will give better response.

If someone has a more powerful engine, and intends to use it very hard (1/4 mile drags, etc') then a billet F/W will last much longer, and disipate heat far better.

For those intending to lighten the stock F/W, DON'T be tempted to go too far. They already tend to crack/craze/warp from heat, so keep to about 7.5~8kg.

Mark.

Thanks Ian..
Paddle or organic????? mmmmmmmmmmm

Mark,

appreciate what you say, and agree that billet should be used if using the car for drags etc for the reasons you say.

Rob, cant read your last email mate, my aol is being stupid today and says 'that email is not currently available', i can read some, but not others
