As per title really.

I'm running an MY96 am having the head gaskets done and clutch while it's all out but apparently the flywheel has a number of cracks in it.

Obviously the option is there to stick in a lightened balanced afair but I would be greatful if someone could let me know the ups and downs of the beast??

As far as I'm aware the car will rev a bit easier (less rotating mass) but will idle rough and be harder to get of the line (more clutch slippage or risk of stalling). Am I talking utter pish or is this vaguely right?

Also would the ecu benefit from a remap if I get one fitted?

In MY opinion, go for an 8Kg mass flywheel, 5Kg is too light for hard effective starts.
Some months ago there was a big debate about this, each to their own.
Only buy any lightened flywheel from a very reputable source, they are mighty dangerous if they shatter...

If they respond, listen to the racers like Andy F,D Wallis and J Banks

Good luck, 911

How's your car doing? Did you get the Head gaskets sorted?

Yes, API David did a good quick job for me. Firing the 'Rice Bowl' up on Sunday, need to bed it all in a bit as the next hill climb is looming!
Gulp. hope it all holds together....

Just had a new clutch fitted (UK MY96) today at Scoobyclinic (only took 'em 4 hours!) so asked them to fit a Fidanza 5.2KG flywheel that I bought locally for ~£350. Idle hasn't changed at all (still rock steady) but the pick-up is much better - definitely worth the money!

Scoobyclinic fitted a 6.8kg Billet flywheel to mine. No idle issues and much more alert when the loud peddle is pushed

Around 8kg is about right if you plan to do drag starts and a competant machine shop will do this on your O/E for not a lot of money. Not a good idea to take the O/E much below this assuming it was in good order in the first place.
If drag starts are not your scene then you can go much lower. You will notice you need some more revs/technique for normal pulling away but that is all. I have used an RCMS at 4.6kg but to be honest I do not think that an expensive flywheel is worth the money.

i've also got the scoobyclinic 6.8kg fitted along with there semi race clutch.
Defo pulls quicker than before.

StickyMicky

all of this "pulling" and stuff, can sumbody actualy say that it makes your car faster, and not just that it feels faster

this has been bugging me for a while, everybody i have spoken to has saod it feels loads faster, but feeling and actualy doing so are diffrent

anybody dropped 1/4 mile times just by fitting a flywheel, and by how much?

ademid

Now your just showing off!

I still haven't got a price for all the bits and work yet but am wondering if I "really" need one..... I guess it'll depend on how much the rest costs.
