Lightened flywheels

[Didz]

it's really not that bad. The part of accelerating quicker is true, and is awsome. yes your revs drop a little, but it's really not that noticable. You just need to shift a tad quicker.

When you go up a hill, it's harder to get up it, as a result you need to down gear. This is to do with inertia.

It is definately a mod that will benefit you.

as you may be aware, there are many different products:

Toda (4.1kg's)
Spoon (4.19kg's)
RG (3.9kg's)

and there's plenty more... like J's racing etc etc...

Just don't get one too light. The Spoon and Toda flywheels are perfect for street, and a bit of track work.

On another note, not once have a dropped out of VTEC when changing gears.

Probably the most accurate post yet.

A lightened fly-wheel will give u better response when accelerating etc... but another drawback most people dont know or forget about is that if you do hill climbing, a lighter flywheel can make you slower up hill.

in transient conditions yes.. (very short hill) as your taking less momentum into the hill

but in steady state conditions (long hill) it will make going up easier if your accelerating.. else it makes no difference if your speed remains constant.

im going to say.. with the already very larger rolling resistance your car generates at the tires.. 4kg of flywheel mass is not going to help you much.. going up hill..

just remember with flywheels if it has a larger mass.. YEs it will give you a rolling start into the hill.. but also it requires more energy to get spinning.. the energy used to spin it up has allowed you to go in with more rolling "inertia"

same idea goes with the lighter one..

its physics

"In short, the law of conservation of energy states that energy can not be created or destroyed, it can only be changed from one form to another"

it holds true to real world applications because its not lost either.. its just changed into heat sound and energy is also used in opposing the resistance ie Gravity in real world.

Great post!

So, to sum it up...

- NO, a lightened flywheel will not make you lose torque.
- NO, a lightened flywheel will not make you slower up hills.

- YES, a lightened flywheel will give you noticeable acceleration benefits in the lower gears
- YES, a lightened flywheel will make your car feel more responsive and make rev matching shifts quicker and easier
- YES, engine braking effects are increased with a lightened flywheel. This is a GOOD thing, not a bad thing
- YES, a lightened flywheel will make your car slightly more difficult to start from a standstill (but you get used to it quickly)
- YES, a lightened flywheel is a great modification and I see no major drawbacks!

finally....

- YES you need to order one if you haven't already got one... !!!

yes right away!! i'm jumping in between ORC single plate, Exedy hyper single.. or just OEM ones with a lighter flywheel... anyone know the lightest available for DC2R?

why do people want a non stock clutch? what is wrong with the stock one?
a clutch that bites harder puts more strain on the trans doesnt it? that's surely a bad thing.. ??

nothing wrong with the stock clutch..

But as it actually cost quite a fair bit of labor.. if you did need to do a change for one or the other .. you might as well do both i think..

depends on your budget.

but i thought this was about flywheels not clutches haha...

i know its about flywheels.. but 99% of the time when people talk about flywheels they talk about clutches... i know that you should change the flywheel and clutch at the same time as the labour costs are high.. but my question is when replacing a used/worn clutch why not just replace with a stock one instead of an aftermarket one?

i think clutch is always down to personal preference..

Oem will always have the OEM feel which some people really like..

IMO.. heavy duty clutch is a tad overated..

all it really is, is a OEM replacement Organic plate with a heaver pressure plate.

i hear alot of talk as well vs the Brass button killing off gearboxes.. its really down to how you drive it..

the more shock you put to the system the more chances of something breaking.. ive seen it done with OEM clutches before but the thing with OEM clutches is that they are FAR MOre forgiving to abusive driving (especially when your gearbox is concerned)

but then again there are casses when there is a need to upgrade to a "stronger" bitting clutch

although i dont know the prices of OEM clutches but usually honda are well known for been a tad hard on the pocket.. and i think as human mental thought processes goes why dont i spend a little bit more on something thats considered "better"

now weather or not its actually better isent the argument but generally the though of aftermarket people always think its "better" (save Xforce)..

but ehh what can you do =P..

i prolly say theres nothing wrong with OEM clutches it.. just I happen to have the same though process of aftermarket clutches are ment to be stronger.. i guess exedy marketing is doing well huh =P...

[Wlee2]

actually to keep slightly on topic..

everyone has talked about lightened flywheels.. but yet no one has mentioned anything about using clutch plates and or preasure plates which a lighter?

these things are actually BOLTED onto the flywheel..

anyone willing to discuss this?

because i have yet to hear much talk about the lightness of pressure plates in any forum

[tinkerbell]

if anyone wants exedy heavy duty clutch and lightweight flywheel combo - PM me for good price


wayne - the pressure plate weight is mostly towards the centre, much less to be gained from lightening this when compared to the OEM flywheel (where weight is all the way out to the edge).

[kookie]

like wise I have a spare exedy + flywheel combo going for really cheap. Thing is you need new clutch pad and fly needs to be re-machined. PM for more details.

[szymonsta]

Please elaborate?

yes please elaborate what is not good about exedy?

Anyone ever heard of Balanced Flywheel and Clutch combinations?

You can mixed OEM with aftermarket and brands with brands but I noticed somewhere but can't remember where that there is such a thing a Dynamically Balanced Flywheel and Clutch Combo.

Can someone please comment on this.

Yea I have the TODA kit, if Im not mistaken this means the pressure plate is balanced with the clutch disc and flywheel to provide even clamping pressure through the whole surface of the clutch material. It prevents premature decay of the clutch and better clamping. The oem pressure plate is not balanced, you can sometimes see areas around the radius where its not clamping the clutch at all
