Light weight flywheel = less torque?

Why do they make clutches pretty colours when they go INSIDE THE BOX!!!?!?!????!?!?!

[PHATR32]

i just asked that question............

[VL-TRBO-RB20]

Hmm you sure it weights 2.5kg??? If so it must be made of carbon kevlar or some other exotic material?

I have 4.8kg chromemolly and the engine revs upto redline alot quicker and i dont see any negative effects with one

it was second hand sam from XTC picked it up for me out of a nismo clutch n poped it in... just waiting for my car!!!! he told me all about it i cant remember what it was but he researched it n new worth $900 n weighs 2.5kg unless my hears gone thats what he told me

So some crazy person will take the effort to make a see-thru housing with neon's that'll let you see the flywheel spin? LOL

Why do they use sterile needles for lethal injections?

U must have heard 4.5kg.

What is it made of? coz $900 is not much if its some exotic material

So they dont get Sued by the persons parents/children... Sorry sorry world we live in!

sorry to bump this up. after reading through the whole thread Im still not very clear on one thing: does it really gives you faster acceleration say for 0-400m drag racing? or does it just "feel" faster because it revs faster?

Ive got a single plate Jim Berry clutch to be installed next week, if light flywheel is as beneficial as most you say maybe i should get one whilst the gearbox is out?

[BaysideBlue]

is this a good flywheel to get?

"Exedy - Single Sports - Light Flywheel

Low mass is a good thing when it comes to high-performance flywheels, which is why the lightweight aluminum Exedy flywheel can help your sporty street ride or weekend racer develop more drive-wheel power. A flywheel is basically an energy storage device. When the factory designs your flywheel, they take smoothness and other drivability factors into account and end up creating a heavier-than-necessary flywheel.

An Exedy flywheel still gives you great drivability, but the Exedy flywheel is made of lighter materials that take less engine power to accelerate. Your engine doesn't make more power and torque, but more power and torque gets to the wheels because your Exedy flywheel isn't soaking up as much of it as your stock flywheel did. Make sense?

Each Exedy flywheel is custom-machined from proprietary alloy metals and specially tuned to the vehicle upon which it is intended to be mounted. That way, your Exedy flywheel always gives you smooth shifting, scintillating acceleration, and steady idling characteristics that you'll love if you're a performance-minded driver. More importantly, you get back a handful of horsepower with an Exedy flywheel, which is what your goal should be with every modification you make"

So are you's saying, when you replace your clutch, you dont need to get a billet fly wheel machined?

also, can you get a lightened or billet fly wheel, lightened more? (if it can handle high power, and ur engine isnt taking a bit off could make it snappier and still safe?)

ive got the exedy flywheel and its just what everyone has said....revs better but also drops revs faster so gear change can be abit rough if not done right. you just have to change your driving style abit. im happy with my purchase.

Just a quick question guys,

I'm getting a Daikin heavy duty clutch installed, and have the option to get a lightweight flywheel. I've heard that I will loose torque if I do. Is this true? Will I notice?

yes. and your gearbox will make awsome ratteling gear noises up to about 2k loaded up

[T04GTR]

drags= heavy flywheel

circut= light one

[deant1]

drags= heavy flywheel

circut= light one

do they make 'medium' weight ones

[Cubes]

Depends what you think loosing torque is.

I found the car felt as if it had more torque especially in first and second when accelerating. I.e it felt as if it accelerated faster.

Launching the car required more rev's as it would bog down easier.

I was able to feel road inclines much more.

Free reving the motor was felt more crisp

Rev/gear matching on corner entry was much easier

High rpm gearchanges seemed easier, appeared to reduce the occasional missed gears and crunches.

Overall.. I quite liked my lightened flywheel. I wouldn't be going too light though. 5-5.5kg's is what I would be happy with.

[(B1) MR_fanny]

true dat to all the above and true dat to the rattling down low in the rev range. the exedy flywheel is around 6kg. i didnt want to go too light.

[Cubes]

I can't say I noticed a rattle down low but I did notice an increase in a labouring type feel at real low rpm. With the stock flywheel on there was no labouring vibration type feel at all. Not that you should be selecting a high gear and going WOT at 1000rpm anyway.

[Gts-t]

for me (having driven a few cars with lightened flys) the biggest drawback is the greater rev drop between gearchanges. that is the main negative in my eyes. if you can live with that, go for it.

This is the only negative i noticed to when fitting and orc flyhweel, u just gotta change a little faster. takes u about 2 gear changes to get used to

[(B1) MR_fanny]

yeah its more that "labour" rattle that i get thats amplified by my dodgy short shifter. nothing terrible so as not to confuse anyone.

[T04GTR]

yeah. subaru call it "garra garra noise" lol
