Fidanza flywheel?

[jory]

All I need to be able to drop the motor in my Spirit is a new clutch and flywheel. I've already decided to get the t2/t3 clutch from TU but I'm not sure if I want to spend the $300 on the aluminum flywheel. Does it really make that much of a difference? I would think so, being 1/2 the weight and all but what do you guys have to say about it on the 3.0? What improvements did it make in the 1/4 mile, the way it revs etc?

Its always one of the favorite 3.0 mods people do from what I have read of others experiences and I love mine.

The long ago 3.0 performance pages document Sebring (last name) going .3 or .4 seconds faster in the 1/4 on his near stock 3.0 shadow and he is also one of the big TD transmission guys. A lot of 2.2/2.5 people bash aluminum flywheels though so I would ignore threads pertaining to their opinions (and they are 99% opinions of people who have never tried one). totally different motor anyways.

Thanks, .3 seconds sounds like it's a worthy upgrade. With that maybe I can get into the 14's. I guess I'll have to buy it and see the difference for myself.

Can you say "Lower Moment of Inertia" ? aluminum flywheels are the Shiznit!

I put one in a WRX Sti and after the install the motor reved alot faster , The customer wasn't expecting this and stalled it first drop of the clutch !! Hhaah

I reccomend em' and i'm an 8valve guy !!

[lookin]

Shiznit! lol I miss that word. So thanks.

I second that. Mine is on the Fed Ex truck and already my car is making 15 extra HP

i was reluctant to go w/ the 2-piece Fidanza flywheel knowing its a steel disc (for clutch contact patch) bolted to an aluminum housing.....but like you guys i was looking for a little more power to the tires with a lighter flywheel......so i "Goldylocks" it.........i went with a Fidanza lightweight all-steel flywheel, its a lot lighter than the stocker, and only a little heavier than the 2-pc aluminum/steel unit....costs more but i retained an all-steel flywheel for reliability and durability.

either unit is a good choice.


i have not had a chance to test the difference since i have not driven the car above 25 mph since flywheel was installed this past summer.

IMO its a total waste of money go to with a "lightweight steel"

spend 300+ dollars to have a 14lb flywheel isntead of 16lb. Id rather buy something else. Cams, make a payment on some ported heads, buy something else neat.

The durability issue is invalid. You replace the friction surface when you change your clutch.

Small diameterAluminum flywheels can have problems (warping) in 800whp turbo motors with poor clutch setups Yes (compared to an 800whp LARGE motor with large aluminum flywheel). Light flywheels are bad ideas when you make that much horsepower on a small motor (for the crankshafts wellbeing)

but not an issue for 100-600hp type 3.0's


basically durability complaints re totally invalid if you are basing them on "what you think might happen" when there are hundreds of people who are using them on your platform
The only complaint I have ever heard was on T M when someone said their clutch was slipping and considering they didnt make that much hp and they had a good clutch, they probably didnt install the clutch properly (or cleanly) and they probably glazed the ceramic discs so they wont grab.

Even with a turbo 3.0 and aluminum flywheel I have NO complaints. In the future my motor might have a stock 3000gt flywheel and I will keep that flywheel because the HP levels I want will be dangerous for the stock cast crankshaft (the limit is a little bit higher with a forged) and i want to do all I can to be responsible. As long as I am FWD I dont have too much worry about it though.

I loved my fidanza flywheel. My car ran 14.2s as most of you know.

Your information on weights is totally wrong. Sounds like someone told you a story in order to sell you an expensive flywheel.
I will again say the durability/reliability comments are invalid.


stock 16lb (free) yay
steel 14lb ($300+)
Aluminum 8lb ($300+) yay

Pretty easy choice for me. Its either stock or aluminum unless I have a TIII 16v turbo and there is no aluminum flywheel that is compatible with the crank angle sensor. Good thing this is the 3.0 forum.

You guys make me laugh !!!

[jory]

lol I'm glad to hear how everybody likes theirs. Now I can feel better about spending the cash on one. Sounds like it's a good upgrade.

ONDONTI i did say both unit are great choices. for sure you cant go wrong w/ either Fidanza unit. from a pure engineering standpoint, a billet steel one-piece flywheel, where there are no differential coefficients of thermal expansion issues, will retain it's flatness over a longer service life.

my original flywheel was toast, ruined, so i had to buy a new flywheel. shaving a few pounds off, and staying all-steel, is never a bad selection.

as for the cost? i forgot, many folks consider $300 too much money.

You have never used an aluminum. Therefore your opinion means nothing vs people who actually have them.

$350 for a shiny looking almost stock weight flywheel. yes, that is a horrible idea.

The steel flywheels are for the T3 guys because the aluminum flywheels dont work with the crank angle sensor.

There are hundreds of peoples personal experiences to weigh against your "theory" and the experiences show your theory incorrrect.



Stock resurfaced or aluminum is the only logical choice. 350 dollars can be used for something much more useful then a fancy shiny looking heavy steel flywheel. Nobody can see your flywheel so the shine is just a joke.

Just because someone tricked you into buying one one by telling you fake weights doesnt mean you should talk someone else in to buying one.
