You can usually find used lightweight flywheels for around 100, I think lighter the better, a heavier flywheel is smoother with a harder clutch.
Poll: Lightweight flywheel or stock?
Ok guys, I need a new flywheel on my car. Here is a build thread so you can see what it is: http://www.d-series.org/forums/entertainment-area/165724-10-1-1-z6-forged-internals-build.html For those of you lazy guys, its a 10:1 z6, staying NA for a few months until after tax season, then a dsm small 16g converted to a 19c will be going on it.
My question is, I'm broke and I absolutely need a new flywheel. My Exedy one has been machined too much and it is now too thin to use. A new one is $220, but I have a stock one with a ton of meat on it just laying around that I could spend $30 on to get machined... I remember when I went from the stock one to the light one that it made a pretty noticeable difference in acceleration so I would really like to put a llightweight back on there. I'm just strapped for cash right now with christmas around the corner and I'm not sure if it's worth it. Let me know what you think.
Especially you guys running stock flywheels, I already know how great lightweight ones are, but I'm most interested in the opinions of people who have had both.
UPDATE: I did a comparison write-up on page 4.

Well I don't want a used one because I'd be sacrificing lifetime there, my flywheel was only machined 3 times before it was un-useable. 2 times were okay, third time it was machined was too much..
I forgot to include this in the original post, but I do have a heavy clutch. It's an action 1md which is an un-sprung 6 puck clutch.

part of it is personal preferance, ive driven both, and i like stiff clutch and lightweight flywheel. you can shave the stockflywheel down to save money if you dont want it to be lighter.
I like my Fidanza. I'd stick to a 12lb'er if you're gonna drag it, I went for the lightest I could on my autox setup.
^^ this.. are you going to drag race this or road race/autox it?I like my Fidanza. I'd stick to a 12lb'er if you're gonna drag it, I went for the lightest I could on my autox setup.
I have a stock flywheel and I don't mind it. I don't think you'll be too disappointed with it.
Thanks guys. Here's the plan: today I'm going to take my stocker to the machine shop and have it resurfaced just so I can get the car running. Then after the first of the year I'm going to get a light one.
This car is my usual daily, but I also drag race the hell out of it. I won't be doing any racing until next year anyway so I think it'll be okay.

oh.... well. If I had known you were drag racing it I would've voted stocker, not lightweight.
If drag racing don't go under 8 lb.
You asked.
You asked.
I consider a lightweight flywheel to be one of the best bang-for-the-buck mods, so Id say it is certainly worth it.
Im not a drag racer, and I understand that people say a heavier flywheel helps you get off the line, but its going to slow you down for the rest of that quarter mile. So I dont think that argument really holds any water, and I still think its a good mod.
If this heavy flywheel theory is true, why would a Funny Car flywheel look like this?

because they have enough power and clamping force for the weight of the flywheel to not matter for them getting off the line
I just put the stocker back on, for now.
I have never heard about the heavier flywheel being better for drag racing, not saying it isn't valid, just never heard it before. I've understood both arguments here though. I was under the impression that a heavier flywheel will make me more likely to spin the tires a lot off the line. This would not be good as I already spin almost all the way through 1st with the lightweight flywheel and I do have an LSD trans. But I also think that the heavier flywheel will help keep revs up between shifts. I wasn't losing too many rpms before though.

Just get a tungsten crankshaft:

Lol in all seriousness though, if you have a small turbo that doesn't take much to spool (plus you higher than average compression for a turbo build) then you may not need to worry too much about falling out of boost too much. I still vote for a stock flywheel for the cost to worth ration.

I'm not sure what all this "falling out of boost" business is.
Don't tell me you're letting out of the throttle to shift...

For drag and daily driving, stock is probably going to be the most user friendly choice. Although, some people, such as myself may still prefer the lightweight. I have a 9lb and I LOVE it, quick heel-toes =D

I going back to stock because I do fall out of boost between shift some of it has to deal with my tranmission the separation beween gears and the big turbo that I am running. I'm also going to a comp clutch sprong six puck with dual pressure plate because my current act is getting wore out but been a very good clutch.
I currently have a 7lb but I don't belive you should run one this light because the fly wheel kinda acts like a dampner for the engine I would stick with something arournd the 12lb range. I know of this because I have a lot of harmonics noise that travels through my car because of the engine.
I think heavier flywheels to a point help with fuel mileage also because it keeps the momentum up at crusing speeds so the engine dosent have to work so hard to keep turning to maintain that speed.

I'm running a 7 lb'er, I don't get any noise from the engine. what about acceleration though in stop and go traffic? I deffinately feel like it has more pick up go, its really throttle responsive. momentum with the 7lb'er sucks for climbing hills though, didtn really notice any difference on flat roads at cruising speedsI going back to stock because I do fall out of boost between shift some of it has to deal with my tranmission the separation beween gears and the big turbo that I am running.
