should i get light weight fly wheel?

[baoanh]

i;m about to change my clutch, should i get a light weight flywheel? :S

Share ur ideas thanks =]

[baoanh]

having EJ8 by the way haha

For daily driving, it's annoying to drive with - harder to shift smoothly and easier to stall

For track, you'll be better at rev matching etc.

Depends what you're after from your car.

[newpaddy3]

If it's a daily driver that never sees any track use then imo it isn't worth it.

[baoanh]

cause i just bought a exedy clutch and exedy clutch cover
about to change them, just wondering if i should just get a light weight fly wheel to put on it
would it make my car more responsive?
daily drive mostly but i do push hard sometime haha

[baoanh]

and i also change my exhaust system to 2" all the way, therefore i bet i will push it more LOL!

[curtis265]

what o.0 what's the stock diameter?!

IMO pushng it every now and then.. don't bother. Only do it if you're a keen track racer Just makes driving annoying - i have one.

The exedy 10.9lbs unit for the D-series isnt too bad for daily - i have it in my car
but other kits like the 7lbs Fidanza will be too light for daily
(stock is like 17lbs i think)

mine does drop revs very quick and makes driving in carparks (anywer slow etc) a little bit harder - but its not enough to stress about compared to the benefits
you will build revs quicker and drop revs quicker - good for rev matching and engine braking
BUT you will loose a bit of torque because of the drop in reciprocating mass
you already have the best gearbox you can get for D series so look after it

do you have an intake and some headers to go with that 2" exhaust?
i would get N*Power headers and Simota Whale Intake from ebay
the headers are 4-2-1 and cost about $200 shipped and the intake is about $150 shipped
the simota intake will sound really good on your D16y8

that will make a really good combination with your clutch and flywheel
i would also suggest getting Energy shifter bushings to be installed at the same time as the clutch and fly
$30 on ebay

to top it all off - get a skunk2 shifter - with the above combination of parts the weighted shift will be awsome

trust me when it comes to D series - i know my stuff lol

[baoanh]

it really make me think now! yea i got Npower header, i got 2" high flow cat and yea gonna install them in for my major service, now i'm really thinking if i sohuld get the flywheel cause i'm changing clutch on my major too and is like 270 on Ebay atm with the exedy one!

[newpaddy3]

He appears to be intent on getting one anyways, so I think what we say wont have a whole lot of effect.

[TheSaint]

it really make me think now! yea i got Npower header, i got 2" high flow cat and yea gonna install them in for my major service, now i'm really thinking if i sohuld get the flywheel cause i'm changing clutch on my major too and is like 270 on Ebay atm with the exedy one!

i got my kit from gripforce on ebay - got both done at the same time

i would get the Energy shifter bushing put in as well

[baoanh]

what is energy shifter bushing for :S

[TheSaint]

tightens up the slack in the shifter and makes shifting more direct and firm
its only $30 and shouldnt be a hassle for the mechanic to install if they are doing the clutch and flywheel at the same time

can u install it urself? i mean where do u install it to O_o

what about that

[TheSaint]

yeah thats the same part - hrm it shouldnt be too hard to do yourself

maybe search around for a Diy?

if the mechanic is doing the clutch and gearbox - just get him to put that in at the same time- should be a 15min job in a proper workshop

[NightKids]

Put the light weight fly wheel in, it's awesome. I had an Exedy lightweight in and it revs good...

[EK1.6LCIV]

dont get one thats half the weigh (I have a 8lb one in my car, wouldnt recommend it to many people)t, but yes if its got alot of ks on the engine by all means get one, very good investment

along with that buy a rear main seal, sump gasket and other seals if its an older engine (250,000+) very good money spent

list:
oem or heavy duty clutch
lightened flywheel
rear main seal
sump gasket
shifter bushings
input shaft bearing (whilst the gear box is off)

theres other misc parts and seals that are bound to possibly be stuffed on an older engine, those are just what I would do if the gear box comes off

[Mikecivic78]

It's a D series, so why bother IMO. Waste of $.

There's my kidney stone of wisdom for the day.

[EK1.6LCIV]

do the flywheel as an oem one is very expensive and will more than likely be stuffed from spirited driving, aftermarket ones are $100 on ebay, Id budget for $2100+ (clutch, flywheel, bearings, seals and misc) install as its a c*** of a job to do and not many will be bothered doing the labour side of things for less than 800

I did mine as the engine gets very good ks to a tank and the car is solid

[Mikecivic78]

Seriously, if you can get one at a good price, and you are doing the clutch, it's worth doing.

While you are there, why not?

Are you planning to do it yourself, or paying for it?

[ks_87]

as long as its not too light, daily is fine. you just have to rev a little higher than normal or go easier at take off.
shifting wise, just shift faster.
both are easy enough to get used to. if you are intent on getting it, that is.

[TheSaint]

There's my kidney stone of wisdom for the day.

D16y8 is like the type-r of the D's

when modding a D its not all about max power - they are cheap on parts, easy to work on and fun to squeeze power out of

[curtis265]

Oh does a light flywheel increase fuel efficiency?

[baoanh]

yea like i said i'm doing my major service, so just wanna see if is worth it to get a light weight flywheel on it hahaha
how heavy is the stock flywheel, 270 for light weight flywheel is that consider as decent price?

i'm sending to mechanic to do it
i cant do it HAAH

[baoanh]

paying for it, cause major service coming soon, i got my clutch and clutch cover, so i'm only need to pay for labour

is that the right one? :S

[Zilli]

flywheel was the best money i ever spent on my car

[baoanh]

but u having B series O_o

[NightKids]

Flywheel gives you supernatural throttle response to smash V8s

[baoanh]

U MUST BE LYING!!!!! i need more ideas~

is that the right one? :S

yes - but its cheaper to buy it in a kit with the clutch

[baoanh]

but the thing is, i already got the clutch and the clutch cover LOL they are standard Exedy clutch haha

[baoanh]

can anyone kinda explain to me the pro and con for changing to light weight fly wheel? :S thanks~

[newpaddy3]

Ever heard of Google?

It's this insane website, you type in some key words and do a search on them, it brings up, wait for it, millions of websites full of info!

I know! It's amazing right?

But to answer you question because I have already put so much effort into this comment, it all comes down to incredibly basic and simple physics.

Thank God for Google because I would never type up an explanation like this one.

The flywheel is located between the engine and the transmission. It is a large wheel of considerable weight by design. At the engine end it is attached with bolts to the crankshaft. On the other side lies the clutch. The outer rim of the flywheel acts as a gear with teeth cut into it. The teeth of the starter motor engage the flywheel teeth and spin it to crank the engine.
Once the engine has started, the flywheel has two more jobs to carry out. As you accelerate, or free rev the engine, the flywheel smooths out the rotational movement of the crankshaft and stores energy. When people say the flywheel stores energy they really mean that it absorbs and returns energy with each combustion cycle. During the power stroke, the crankshaft is being twisted (pushed by the piston) and during the compression stroke the crankshaft is doing the twisting (pushing the piston). The flywheel absorbs the energy when the crankshaft is being pushed and returns it when the crankshaft is pushing. The faster the engine is turning over (high rpm), the more energy is being stored by the flywheel.
When selecting a weight for the flywheel, car manufacturers need to consider (among other things); engine acceleration (a lighter flywheel will build speed quicker than a heavy one, but drop revs too quickly) and inertia (a heavier flywheel carries speed further, but is harder to slow down than a light one). It’s a balancing act and production cars strike this balance well for their intended use. Also, the larger the car, the heavier the flywheel required.
A race car on the other hand is usually very light and does not need to concern itself with going to the shops to pick up milk and cookies. A lighter flywheel, within reason, is used to reach the redline quicker and to control the revs with greater precision throughout the range. Many weekend warriors buy lightened flywheels for their cars and nearly all video game racers have at some stage purchased the ‘lightened flywheel stage 1 kit’ which adds at least 35kw to their car. In reality, the weight of the flywheel is more of a preference thing and does not add power to your car.
If you accept that you will accelerate faster with a lighter flywheel, you also have to accept that you will lose speed faster and have to work harder (more frequent input) to maintain your momentum. There isn’t any power increase in the scheme of things, just a change in the rate of rotational momentum and the storage efficiency of this momentum.
Let’s look at some examples.
Harry and Larry are twins and two months ago they turned 18. Their sugar daddy (ed: name removed under court order) bought them identical cars for their birthday and gave them some spending money. Harry spent the money on 3 midget hookers while Larry installed a lightweight flywheel in his car. Their cars are identical except Harry has a heavier flywheel and Larry has a lighter flywheel.
To show off their sugar daddy rides, the boys decided to cruise George Street on a Friday night. On their way they encountered lots of traffic. Larry discovered that his car now accelerates faster. Each time he steps on the gas the revs respond quicker but when he changes gears he noticed that his revs drop off faster as well. He had to adjust his driving style to shift quicker. He also noticed that he was using the accelerator more frequently to compensate for his fluctuating speed. This did not please him since he couldn’t cruise in a relaxed style like Harry.
Halfway through George Street, to his surprise, Larry stalled his car trying to take off from a set of lights… on several occasions. Quite an embarrassing situation and he attributed this to the flywheel since Harry had no such issues with his factory spec flywheel.
When the boys passed The Rocks, they came across some clear road. Larry looked over to his brother who nodded in agreement. They, like many of their peers, live their life a quarter mile at a time. A furious drag race commenced. Larry noticed that he could shift earlier through the gears. It was like his car felt lighter to his engine and his instincts proved right. His lighter flywheel effectively lightened his car.
Unfortunately for Larry, he missed a gear and his revs dropped quickly which allowed Harry to catch up. Side by side the boys raced while the world warped around them. A quarter of a mile seemed to last minutes. Larry was amazed to discover that his flywheel didn’t actually give him more horsepower like the guy that sold it to him promised.
All of a sudden, the boys saw a defect station up ahead. They both geared down to assist their brakes with engine braking. Larry’s revs shot up very quickly to match his wheel speed and didn’t slow him down as much as what Harry’s car did. The lighter flywheel just didn’t offer enough resistance to change in speed. Seeing that he could not slow down in time, he made a rash decision and started to drift his way into a side street before the defect station.
Very quickly, Larry discovered that the lighter weight of the flywheel hindered his clutch dumping. He had to use higher revs and it was harder for him to break traction which he suspected was related to a lack of weight behind his flywheel. Like a pro, Harry easily overtook his brother while drifting on the outside lane.
Dirty with his inability to drift donuts to get chicks numbers, Larry dropped the hammer and went all street racer style on his brother. With a few tight back street corners between the brothers, Larry made up the difference in no time and was grinning into the disappearing reflection of his brother’s car in the rear view mirror. He realised that the flywheel he had installed was well suited to high rev driving and accelerating out of corners as quickly as possible.
So in summary:
City driving
acceleration has improved with a lighter flywheel
the engine has to rotate less mass so it works more efficiently
you will have to adapt a new driving style to avoid stalling
gear changes are more frequent and need to be executed faster
it requires more frequent adjustments to maintain cruising speed and hence burns more fuel
Drag
acceleration, as above, is quick with a lighter flywheel
you run through the gears too quickly, spending precious time off the accelerator
when changing gears, you lose more revs
a lighter flywheel does not add horsepower
too light a flywheel in a heavy car will struggle to get it off the line quickly
Drift
the lighter the flywheel the more revs you need to break traction
the fluctuations of a light flywheel require more frequent adjustments upsetting the balance of the car
Race
a lighter flywheel is an all round improvement
quicker acceleration
lower effective car weight
precise rev control

Quite sure this whole thread has been directed at that..

Go easy on him man, he could have down syndrome.

whats this T_T

[newpaddy3]

Do you need some more explaining?

How can I be of assistance?

[baoanh]

nah i'm ok thanks!

ROFL sugar daddy lol who ever wrote that shit must of been a creative mofo

If you're driving it on a track, get it. If you're only driving it on the street, don't. Overtaking a couple of people isn't worth the hassle. Almost any driving that will benefit from a lighter flywheel is illegal anyway.
