Lightened flywall...pros? cons?

[Deleted member 66701]

With a lightened wheel you get there much faster and by the time the rev limiter acts you have more overshoot than a heavier wheel.

With a lightened flywheel you should drop your rev limiter by few hundred to protect against this.

I dropped from 7100rpm to 6700rpm on the Pinto when the steel flywheel was fitted.

go from 5th to 2nd instead of 5th to 4th, itll die just as badly, standard or lightened flywheel

This simply isn't true. With a heavy flywheel you at least have a chance to recognise you have screwed up because there will be quite a lot of retardation as you lift your foot off the clutch, giving you a small chance to correct things. With a super light flywheel there will be bits of valve in the pistons before you know what's happened.

I picked the wrong gear once on my Escort and there was a delay before the revs went through the roof, I managed to dip the clutch in time and get it in the right gear. If i didn't have that delay it would have possibly been the first Endura-E engine to hit 12k revs

ive had the lightened flywheel on mine for a year, yeah ive got the odd down shift wrong from time to time, but its obvious when you do, like blindingly obvious... if someone cannot figiure out if theyve slotted the wrong gear when they start to bring up the clutch they shouldnt be bothering with modifying cars

Your's cant be that light then.

 

[Housey]

Mine is well light, its yellow and covered in flies.

As Simon says, it's can't be a very light flywheel, and you must be doing very careful changes... I suppose when you change down you just let the synchro whine away and gradually lift the clutch up? If you are doing a fast change and matching revs, then you very quickly let the clutch out which doesn't give you a chance to correct things if you are in the wrong gear.
