So basically what i'm asking is if a lightweight flywheel such as the fidanza which is 8 lbs I belive makes a huge difference..put it this way....say if you had 2 bone stock cobalt ss/sc's...they both pull exactly the same, have the same exact drivers...anyway, if one had just the flywheel and raced against the other stock ss/sc, how hard would the one with the flywheel pull on the other stock one?

Reason why i'm asking is because i'm going to be installing my clutch soon and i'm trying to decide whether or not to buy a lightweight flywheel or not...thanks in advance

 

Yes there is a big difference in acceleration on light flywheels and its a good thing to replace it when you get a different clutch

 

less rotational mass = faster spinning = faster acceleration

same concept applies to rims/tires

 

the side effects are also just as noticeable... rougher idle, harder timing on shifts.

 

Except that in this case, the stored energy in a rapidly rotating flywheel is utilized to ACCELERATE these other components, during the first critical couple of seconds of a drag race.

You will find that generally, cars which are not traction-challenged benefit from a little more rotational inertia during most short-duration street drags. These vehicles have trouble getting rolling, and the flywheel acts like a stretched rubber band, whose stored energy is suddenly unleashed when the clutch pedal or the trans brake are released.

What matters in relation to your choice of a light or heavy flywheel, is how you are going to use your car.

 

isnt it true that a lighter flywheel can make your rpm drop faster? cause the rpm in these cars falls like a feather...

 

it would make sense. the lighter it is, the easier it is to spin, and also, the quicker it "stops" spinning. (even though it never really stops unless u are shifting, it was for an idea.)

 

When I went with the lightweight flywheel, it did rev a tad bit faster if I reved it in neutral...didn't really drop that much quickly though....however, big improvement in acceleration....definately noticeable and definately worth it....however I believe it makes your cluthc feel a tad bit mushy and you have to use/slip it a tad bit more than with the stock flywheel in order to get going under normal driving conditions

 

interesting... im not down for replacing the fly anytime soon though haha, so ill box the idea till its worth looking into

 

it's a big performance boon, my fidanza def makes the car faster.

as far as the RPM dropping, that's because of the electronic throttle body, if it was mechanical, it would drop a hell of a lot faster.

 

interesting... i really dont know whats involved in replacing the flywheel on a car like this come to think of it.

 

Rule of thumb, replacing clutch you should get a new flywheel. In the end after getting OEM shaved down its just as much.

 

well... im pretty happy with the oem clutch though... what can i hope to accomplish with an aftermarket clutch?

 

well, in my case, a hard launch cooked my stock one...

but, basically, it can take more power without slipping, so you won't roast it as power gets higher.

not that i make that much power, i just wanted one that could take anything reasonable.


and, as far as putting it in... step one is to take the transmission out.

 

gah... i dont want to have to deal with a transaxel anytime soon, haha ill reiterate. idea is boxed untill further notice!

come to think of it, the day i do the flywheel and clutch (if i do) will be the day i do my mounts. and that will be the day i get someone to pull my engine, and take it apart for a port and polish, and to powder coat the block and poilish the rest. but that day wont come for some time i dont think.

 

yeah, i have a header/DP sitting in my garage, waiting for the day i take mine back apart.

 

well header/dp is my next venture after getting better tires. probably gonna go with the vibrant setup.

ive looked into doing the headers, and its seems a lot easier than taking off the transmission! haha, you should get those on there!

 

well, the header is still a PITA. with the subframe removed it'll be a matter of a few bolts, so i might as well do it while i'm down there. i'm also thinking i may do mounts while i'm at it.

 

yeah, mounts are ftw, i just cant justify intalling any untill ive done my full exaust system, but $$$

 

i did the poly fill on mine, it helped a lot, but it kinda shortens their life.

 

if you need a fidanza fly wheel... i have a brand new one for sale. hit me up

 

why is it extra?

 

im sorry, poly fill?

 

PM us we can get you a TTR Mount for a really good price, if you purchase a flywheel

 

TTR Mounts would be on my list way before a flywheel .
