Just want to know if anyone is running the Fidanza Flywheel with boost. It is at a good price and similar to the Clutch masters, Just got iyt and I am boosting just wondering if I need to worry about it. I know it is late but that is not the issue.

I have an act xact prolite, which is roughly 9 lbs i believe, with the xtss clutch. I never have any problems with it, i was really suprised when i drove it the 1st time. The way some ppl make them out to be, i thought i was gonna have to learn to drive all over again. Only stalled it once cus i was being lazy. Install it u'll like it ;D

drintegra

thanks, I was wondering cause this one is lighter then the ACT, A friend has the act and it feels normal to me. Also this on e has the friction surface, just wanted some people who have used it. thanks

i have a fidanza flywheel, and I felt absolutely no difference in drivability. I only noticed increase in aceleration. I don't know why so many people complain about having a 7lb flywheel.

YEA SAME HERE. i ahve the 7 lb fly wheel and acceleration is way faster, but i dont really see a HUGE difference in drivability. you'll get used to it.

aluminum flywheels IMO arent as good as chromoly forged steel or forged steel flywheels, friction plates wear out over time and are expendsive to replace, driveability on a lighter flywheel wont effect much or give you a big noticeable difference in the way you drive, but you will be able to tell over stock

drintegra

anyone else?

Wow, I always read that LW flywheels were a pita, causing stalling out and everything.

Is there a certain weight any of you would reccomend? 7lbs, 9lbs, 12lbs, ect.

b18sihatch

most people just choose one, and not think of weight, but depending on the application the flywheel is going on should depend on the weight you choose, lighter for a track car like 7lbs. for daily driver like 9-12lbs. having a lighter flywheel will increase and decrease the rev faster as you are lightening the rotation assembly

how strong are the aluminum one do you have to worry about them breaking?

b18sihatch

Aluminum have been known to break, not very often but that is a chance you take, they are alot weaker than the chromoly forged steel or forged steel flywheels. normally aluminum flywheels are 2 pieces and they have been known to come apart, also exedy and other flywheel manufacters test their flywheels up to 15,000 rpm, aluminum flywheels can break at high rpm yada yada

According to something i red the other week Exedy flywheels are machined from one solid peice and then tested to 15,000rpms, as well as them claiming that they dont "explode" if left under 15k.

Exedy makes solid products and for no reason would i not trust a part from them. Every time i have used their clutches i have expierenced no problems as well as pushed 10-20% more power than they claim out of their organic stage 1 clutch. Solid products spawned from great R&D.

Here is what Exedy "claims"

Exedy Racing flywheels are made from solid one-piece billet chrome moly steel or chorome moly steel forgings. They are specifically designed to reduce weight and intertia for better engine response. Most models incorporate special design features to enhance the airflow and improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel which has the possibilities of separating form the flywheel and exploding. This is caused by two different expansion coefficients (aluminum flywheel pressed on steel ring gear). Exedy steel billet and fored steel flywheels have passed engineering tests of up to 15,000 rpm. And is guaranteed to be explosion proof at the said rpm.

b18sihatch

i definitly second that. fidanza IMO isnt that great of flywheel maker as 1 piece billet steel instead of 2 piece aluminum, you do the math

b18sihatch

i feel it is very nice of exedy to point out the possiblity of a aluminum flywheel will explode lol, great marketing to gear the buyer towards sumthnig that wouldnt explode, but ont only that its fact, so thats how they roll lol

urbansi

You get what you pay for, **** why do you think forged pistons are made from one solid peice, and after market rods are not cut at the rod caps but cracked to keep strength etc....
