Changing my Clutch - Will I regret not getting a Lightweight Flywheel ?

[CONSIGLIERI]

Hello friends ! I need some advice;

I'm changing my clutch to a XTD Stage4 but I'm considering NOT changing my flywheel to a lightweight flywheel due to LOTS of complains about the revs dropping too fast almost making the car to stall...

Will I regret this decision later ? My car will be a basically DD, NEVER for Drag...

Is there a flywheel that's just a little lighter than the stock one, but nos as light as the Fidanza / Act ?

Thanks !!!!

If you are using it as a DD you will not regret keeping the stock flywheel. Weight is evil, but only in performance quests. Upgrading to a lightweight flywheel increases throttle response sure, but it also creates more strain on the crank believe it or not. Imagine spinning a bucket of water around fast so the water stays in... that is your stock flywheel. It is smooth and spins pretty evenly. Now do it with an empty bucket.. makes it a lot rougher right? That is the reason why manufacturers use a heavy flywheel, to help the engine run smoother. So for a DD a stock flywheel is fine.

Thanks for your reply man... I was asking this mainly because of the driveability. Some people even complain when parking the car...

So, since this will be my DD (sometimes only weekends) and I'm aiming at 400whp MAX someday, I thought it would be better to just stay with the stock flywheel

Thanks friend. That's one of the topics i've read these days to make a decision (still dodn't)

I am running a Lightened Fidanza flywheel, its roughly 11lbs. Compared to stock 18-19 lbs that is a huge difference. Its a considerable difference in performance and feel. I had a huge increase in throttle response. I am sure there were other factors involved in the new feel, at the time of the new flywheel installation, I also had the clutch replaced as well as the TOB, fork pivot etc.

I really like the feel for a street driven car, and would recommend it to others.

People usually complain of driveability issues with the aluminum flywheels which typically run ~7-8lbs. Personally I'd still ditch the stock for an ACT streetlight version, which run ~12-13lbs. This removes enough weight for the rev to be quicker but not enough to have driveability issues.

What ever one you descide to go with, just verify that it has the correct step height. Even brand new flywheel can be stepped incorrectly.

Thanks. That's what I thought... Many many people complain about even trying to make the car move from a stop... Having to rev up to 2k rpm so it do't stall... that's weird

I actually hate my fidanza lightweight flywheel. Go figure.

I definately second this. The ACT Streetlight is what I run with an ACT 2600 in my DD and it is not a problem at all. I personally don't think I would want to go lighter though. The Streetlight is the perfect balance of quick reving and drivability; that's my 2 cents on this anyway.
Another option is to have your stock flywheel lightened by RoadRace Engineering. I did that with my last 2g GSX and it was also a DD and worked very nice.

I kept the stock one with my first GST and did an Excedy Stage2 and never had any problems.

The answer is no.

But that doesn't mean I don't love my 11.7lbs chunk of chromoly.

 

[silvreclips]

I didnt notice any drivablility issues when changing to mine. I also run an aluminum UDP. Never had issues with the car stalling. I would recommend changing it out.

I've never heard of people having issues with an aluminum lightweight flywheel, like revs dropping too fast. Either they don't know how to drive, or something else is at fault.

It's tricky greeting used to the new feeling of a lightweight flywheel over a 20lb chunk of metal.
But you'll eventually get used to it.
I have a Fidanza one, but I would recommend RRE's chromoly one or ACT's.

I had the Fidanza aluminum flywheel and I agree, for a DD it sucked. the engine would stall to easily because of such a reduced amount of rotational mass. a 2.0 at 8.5:1 compression have about 30 or 35 HP at idle (based on what my last dyne run had) The weight gives it a little more momentum, which helps with starting from idle and fast deceleration. It I would press the clutch at road speed, the engine would stall. I am nor running the ACT street-lite and it's a night and day difference. So, I would stay away from the Fidanza. I have also heard stories of the starting ring gear falling off. Just my .02

I also agree. I have the act as mention. It is okay as in rev wise. But this kills my car when I go to the track. It causes my car to bog off the line. My stock never had this problem due to it being heavier and more momentum to keep it spinning.

But no, you will not regret. I haven't tried other flywheels but my act doesn't bother me. But honestly I feel that money could be spent somewhere else in parts. Since I installed my flywheel, I understand the hassle of what people say that it rev's faster. I don't even notice.

Thats not the flywheels fault, thats the drivers


I've had the ACT Streetlight for 7-8 years & there's no issues with it, my car is a daily summer driven car. Some people don't mind the slower rev's with a stock flywheel, but personally I'm not a fan & would actually regret not installing the ACT. I can't really recall how much slower the free rev's were with the stock flywheel as I haven't used one in so many years but I know on my other vehicle it too has a heavy factory flywheel with slow rev's. Its not a performance car but if you try to rev match on down shifts, its alot harder vs a lightened flywheel & as far as performance driving goes, I do not like a heavy stocker.

Get the ACT Chromoly FW. You'll thank the people recommending it.

 

[MichaelSuch]

Running the fidanza aluminum flywheel here, have been for a few years now without any problems with revs dropping to fast or anything. I could instantly tell a difference in throttle response and how much quicker the engine reved. I would run a lightweight flywheel in any FWD.

I want to change my clutch too, is the XTD Stage4 a really good setup? This will be my first performance clutch. I will do a little bit of drag prob once a week but other wise it will be my DD. Should i get the lightweight flywheel? Is stage 4 a big jump from stock? Was thinking more stage 2.

Hey friend ! I'm also on the stock clutch. Why am I changing to Stage 4 ? Because I've heard a lot of goods reviews about the XTD Stage 4 UNSPRUNG. Stage 2 and 3 are CRAP according to most people here so I jumped right to the Stage 4 Unsprung of course...

Do as people here are saying and get a ACT that is a little heavier than the Fidanza.

After heating the friends here, I guess I'll do it

What a lot of people are noticing with the bogging off the line is the lower torque their engine has because of the lower amount of rotating mass there for they must increase their RPMs to compensate for the lower weight on the reverse side of that less weight on the crank will help horse power up top there is always a trade off.
