Celica Forums General Discussion Exterior flywheel?

I know may be there are many post about this but I did a search and I didnt find anything. What is the fuction of putting a lightflywheel in your car????. What it does to your car???...Is good or bad for the car??

Reduces rotational mass which means it frees up your motors horsepower.

if its to light its not good for daily drivin as you may have to shift more often, i think

Frees up Hp??? Actually the rotaional mass being reduced in turn helps you acclerate faster due to the fact that it takes less power to turn the flywheel so the engine gains revs faster and also losses revs faster when you let off the gas. The same can be said for weight reduction the more weight you shed off the car the less it will have to pull so it turn the faster it will go, but it will never show any HP gain on a dyno.

Yeah, mine is the draw out version.

hmmm...i have a question.

i'm not to familiar with the in-depth info on auto vs manual.

can you install an aftermarket flywheel on an automatic?

just wanted to know

no, you can shift whenever you like. What's bad about better acceleration? It saves gas too because it takes less effort for your car to get up to speed.

Do a search someone has mentioned that before.

Yah, there is no difference in the flywheel between a standard & an auto as far as I know.

Rotational mass works exactly the same as a stationary car. It takes energy to make it move. The lighter it is, the less engergy it takes.

Like I said, it frees up horsepower already there, not creates it. It will show up on a dyno when accelerating; but no, it won't effect peak horsepower because there is no advantage there.

Either way, we are talking about minor differences.

^^ what he said and..

if it's too light it's not good for daily driving because of stop and go traffic etc- and when you're daily driving; you end up wasting more gas because you have to hit the 3k mark to actually go anywhere, where before you could just accelerate slowly at 1k.

A car with a too lighweight flywheel is funny to watch in LA traffic.

A lightweight flywheel does nothing to your torque or hp really; all it does is put you in your powerband faster

Exactly I realized this after I posted its all good

who cares about daily driving????
If there is traffic, I just wait for the car ahead of me to move 50 feet before I engage my clutch so I don't run them over. When there is lighter traffic, I race all day every day and leave the slow majority behind. Ahhh how I wish the roads were more like NASCAR, but then only a few people could get a license, based on skills/reflexes. Oh well...

hmm...so there is no difference between the two transmissions. so would it be a good idea to buy and install an aftermarket flywheel on my auto?

(ps: dont flame on my auto. but it would be funny to hear something like:
"the best idea would be to trade in your celica for a
stick-shift and then get the flywheel mod."

yeah, I guess it's diffferent that I have to drive to work daily, and make an OC-LA trip at least twice a week, usually in traffic.

of course you can shif when you want

but because the RPMs climb higher and people shift normally around 3k to save gas and be easy on the engine you have to shift more often

One more thing about the flywheel, it off course makes your RPMs WAYYY easier to increase, but it also makes your rpms drop faster too

Do you have a lightweight flywheel? Just wondering???
Daily driving is fine for me...I can shift at 3k and so what if I shift more often...how is that bad for daily driving? You still haven't answered my question...

And even though I have a lightweight flywheel...I can induce slower acceleration at will with my exhaust control valve. So even I didn't want to shift that often...I can adjust my car on the fly to compensate for it.

Personally, I dont have a lightweight flywheel. For the 6th gen celica, the options are limited and the ones that aren't "too light" are rumored not to have the best manufacture. I have driven cars with lightweight flywheels and also cars with lfws and racing clutches tho, so I know the effect.

Ok, so you shift more often, you have to wait 50 feet in traffic so that you don't slam into the car in front of you- it's all personal opinion man. Whatever floats your boat. It's my expierence that they're a pain in traffic, because a lot of times I'm on my cell for work, or doing a number of other things. it's why, after careful consideration, I bought an automatic.

It's just all personal preference, and therefore, your opinion is no more valid than mine when it comes down to if we like shifting more, etc etc. If some people think lightweight flywheels are a pain in day to day, why shouldn't he hear that opinion? Both of ours are legit.

no flywheels for an auto doesn't do the same thing can get shift kits and or im sure you can get new torque converters (i know for my s-10 and a lot of other autos you can) they will rasie the rpm where your car will start moving so instead of the motor moving the car at 1k rpms it will move it at 2k so you get closer to your engines powerband

hhahaahaa...I wasn't even talking to you Shidarin. Look who I quoted..

&(*&(* I thought you were! Sorry, I was like: huh!? he hasn't asked me anything!!! *sob sob* I'm goign to go clean my post up now

ok, to quote you, shidarin:

"It's just all personal preference, and therefore, your opinion is no more valid than mine when it comes down to if we like shifting more, etc etc. If some people think lightweight flywheels are a pain in day to day, why shouldn't he hear that opinion? Both of ours are legit."

I agree. But RaverTony generalized and said it's bad for daily driving...I'm saying not necessarilly...it depends on who you are...where you live, etc, or what you are willing to do to have a real daily driven race car. BTW there are a lot of people out there as loco as I am about racing

I'm pretty loco on it too, but I just take a different, lighter approach to it. I keep hearing you 7th gens have "moderate" lightweight flywheels that you can actually.. get this.. drive through parking lots in! this makes me jealous. If that were the case for hte 6th gens, or even a little less or more, I'd more than consider it.

you can always have one custom made...just an idea.

ok, well I actually have a lightweight flywheel and it is the lightest available one for the 00-up gts, "fidanza." A few things, You don't have to rev to 3k to go anywhere, you will have to give it a little more gas and slip the clutch just a slight bit more but you can keep rpms under 1k and still go from a start. I normally rev to 1.5k before i go and the rpms will drop to 1.25 or so for tight traffic. You will be amazed at the acceleration during daily driving. Your car with feel like it actually has power from 3k-5k out of lift. RPMs will drop a lot faster, consequence is either shifting fast as crap or modulating the gas on shift to keep rpms falling slower to next gear, otherwise you will get that surge of the engine turning the rpms back up like when you downshift with out revmatching. I've heard quite a few different views on weather or not you will show gains on a dyno, but from the people who actually have a flywheel and have dynoed thier car i have heard that it does show up and you do gain a good bit of hp. I've heard from two people that they gained 12-15 peak hp on a dyno with the fidanza flywheel. I personally am not sure but it seems as though it would show up on a dyno, i mean its just like ligher wheels except a whole lot more important cause its spinning 8k times per minute at redline. I personally love my flywheel and it has changed my driving experience. It will take time to adjust to a lightweight flywheel, but i believe its worth it. Its also a lot tougher to land lift with lightweight flywheel.

PS I actually have a lightweight flywheel

AMEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i don have a lightweight flywheel on the celica (u caught me ) but installed on another car plus my uncle has one too
like you said daily driving is fine for you with a flywheel, but i was tryin to let the original poster know about this

of course ur a racing fanatic so it wont bother u.. i love to shift too thats why i bought a 6speed.. and to answer ur question simply, it just will make some individuals uncomfortable and thats how it may be bad for daily driving that is if its manual

of course your right it doesnt apply to everyone, i wasnt tryin to make a general statement and thanks for noticing that

Ok I have a Fidanza lightweight flywheel on my 00 GT and let me tell you there is a noticable difference. Ive never dynoed my car so I cant tell you if there was any hp gains, but the concept of the lighter flywheel is to create less rotational mass and thus freeing up hp not make hp. And no automatics do not have the same kind of flywheels as standard cars autos have what they call flexplates the only thing you can do to beef up an auto tranny is change the gears inside or get a higher stall torque converter.

The flywheel on every other motor on the planet is exactly the same for an auto or a standard; why is the Celica different?

they are diffrent belive me

you find me an auto tranny lightened flywheel

above guy is correct on an auto theres the flex plate which is only used for the starrted to start the motor then it goes to the input of the torque converter then the output of the torque converter goes to the input shaft of the tranny

manuel is flywheel clutch tranny...

Auto transmissions don't have the same type of flywheel, they don't even call it that, it's called a torque converter.

YOU CAN"T INSTALL A FLYWHEEL ON AN AUTO...They don't have one!!!!!!!!!!!!!...you need a higher stall torque converter, and shift kit

a flywheel is a flat plate looking piece that works with manual trannys...a torque converter is a housed pie looking piece that slips on its own to create the proper stall (you start your takeoff at a higher RPM)...I had an automatic on my last vehicle, I had Turbo, and an auto (it was a custom Turbo on a 2000 dodge dakota and my aftermarket stall converter was at 2,200 - 2,800 rpm...so I started right before the Turbo spooled, and launching was nuts...destroyed gas tho

for most people it's not good on stock ecu cause people that barely land lift will no longer be able to land in lift. which would cause you to slow down quite a bit.

How do you think you are going to start your engine without a flywheel? I guess us automatic guys have to kick start them?

Every motor in the world comes with the flywheel attached & then you bolt an auto or a manual tranny to it.

Okay, here is a basic diagram of a 1ZZE/2ZZE with an A/T (Automatic) and M/T (Manual) setup of the flywheel. Although the diagram doesn't quite clearly show it, the two flywheels are probably identical, then you start bolting stuff to them like a torque converter or the clutch assembly.

A lightened flywheel if it does anything, is definately a good thing. In a standard tranny, once the clutch is engaged, your engine is LOCKED to the road. There is no slippage. SO, if your engine reaches the uper range of the RPM's quicker, that means you just accelerated quicker! That is definately a good thing.

Once the clutch is pushed into to make your shift, you are waiting for the RPMS to drop to make your shift. Theoretically the reduced rotational mass will mean your engine returns to a lower RPM quicker which will allow you to shift quicker. Definately a good thing.

Rotational mass does help your engine idle, in theory if you reduced it enough, the engine would have a more difficult time going from firing stoke to firing stroke & your idle would be a little rough. No biggie, adjust it up a few hunded.

The RPMS of your engine when you shift & so on is determined by gearing, not a flywheel. So it won't change any of your shift points.

it still doesn't do the same thing as it does on an manuel

basically its only function for an auto is to start the car you ccan't go smaller cause then the starter won't be able to turn it

go to howstuffworks.com im sure they have something there to show you the diffrence

and like i said i challenge you to find me an lightend auto flywheel(flexplate)

lol this thread has been gettin ugly

Lightened doesn't mean smaller. Its probably made of a different metal composite, or it could have larger holds drilled in it to save weight.

No you won't find a lightened flywheel for an automatic because there is only one kind of flywheel. They are for both automatic and standard. The flywheel is an engine part, not a transmission part.

an auto flywheel(flexplate) has bolts to hold it on to the torqe converter a manuel doesn't so it doesnt have those bolts so its not the same flywheel why can't you admit that you were incorect

hell it doesn't even have the same damn name

If your so damn right, prove it. At least I have gone to the trouble of finding information.

scroll down to step 10 where they talk about removing the FLEXPLATE http://www.technovelocity.com/chevyhackers/tech_articles/torque_converter/torque_converter.html

does that apear to be a torqe converter attached to this so called flexplate yes it does do we have bolts or holes on are manuel transsmissons for a converter no we don't there for there diffrent

step 17 shows you a flexplate

and if you scroll down to the flywheels ou can see there not the same http://www.ws6.com/slpclutc.htm

So you are saying a standard tranny vehicle does not have a flexplate?

did i say that ?

To me, when I see the so called flexplate, that is what I call a flywheel. From now on I will call it "round metal plate with teeth".

The "round metal plate with teeth" is part of the motor. Vehicles with both standard and automatic have this "round metal plate with teeth". In the link you sent ( http://www.ws6.com/slpclutc.htm ) I see the "round metal plate with teeth" bolted to the back of the metal plate.

Crate motors oftem come with the "round metal plate with teeth" from the factory. They are not buit specific to the type of tranny you have.
