Wanted to know everyones thoughts on lightweight flywheels vs stock flywheels (LNF). I cant remember the forum members name but i was told that the stock flywheel was better with aftermarket clutch, i guess the heavier flywheel builds boost better, BUT i always thought with a lightweight since you can more free revs it would do the same. My clutch is a Spec stage 3+.

 

Don't some of the lightweight ones cause misfire problems?

idk im tryin to figure that out when i brought my car it had a clutchmasters flywheel on it i didnt have any misfire issues, i got my hands on a Spec clutch and wondering now should i get ttheir lightweight fly or stock.

 

Honestly, I've always prefered the feel of a stock weight flywheel. Lightweight flywheels make it much easier to fall out of the powerband but also much easier to reach into it. Light flywheels do have more response but it makes clutch engagement more difficult and more finicky as well. If you're street driving this car, the optimal feel and street performance will be obtained through the use of a stock weight flywheel. This is totally my opinion though, it's here for your reference and knowledge if needed

I've got the Fidanza flywheel in mine. It took some getting used to as far as getting moving from a standstill when paired with a stronger clutch. On that note, it revs and accelerates quicker, but that also means that the revs will drop quicker when you're shifting (similar to when the A/C is on), so you'll need to adjust your shifting habits. An additional advantage to aftermarket flywheels is the fact that you can replace the friction areas on them instead of needing to machine/replace them.

No misfire issues, ever.

 

Stay with stock. I'm supercharged not turbo but I'd rather have stock. Stock flywheels I've been told make more low end torque plus they are just easier to drive. I can drive mine fine now but it took some major getting used to when trying to get the car moving. Never caused misfires on mine but they've also been known to not absorb vibrations as well as stock and it shows up as false kr.

 

My car does something a bit similar I think. It will suddenly bump back and then reapply timing as the tranny loads/unloads over a bumpy road, but it doesn't register as false knock in my case. It's most noticeable when using 93, but goes completely away on E85, due to the increased timing.

 

Mine does it occasionally but it's not the tune because it just pops up once in awhile. Doesn't matter if it's WOT, cruising, light acceleration. I like how freely it revs now but I don't think the benefits outweigh the downfalls

 

Thanx for the input guys i was use to the Clutch-masters lightweight when i brought the car took bout a week, but got it down paccd but for this build was wondering cuz i didn't want to kicc out $400 for the Spec fly to match their clutch which i was told is the best option when running that clutch. But i got a deal on a spec flywheel bout few bucks more then the stock fly, so i will picc that one up and just have the stock one machined in case i dont really like the Spec, also im selling that Clutch-masters fly too.

 

questioning this myself

 

Most of the serious racers use a stock flywheel. Makes more hp on a dyno with a lightweight, but launching and accel suffer
