ive heard a couple of differetn stories...

ive heard of people puttting them in and saying they didint feel a difference

ive heard lightweigth is better

and ive also heard lightweight is bad for an n/a motor because it drops the rpms down too low during shifting..

ive never driven a car with a lightweight flywheel and just finished building an ls/vtec with a gsr head itr pistons and just got a S4C tranny but still dont have a clutch pressure plate or flywheel...

just looking for some input

 

I felt a difference and I like the flywheel. Only time it drops too quickly is with the AC on

 

it revs a little bit faster, but dont tear the car apart just to do that flywheel.

wait until you need a clutch, or a throwout bearing or something.

 

Lightweight flywheel reduces crank to wheel hp loss by having less weight for the crank to turn. You will notice a difference in revability when you put it on, not necessarily when the car is under physical load.

A lightweight flywheel is great for an N/A track car. However, a drag car will probably not benefit from it as a heavier flywheel will hold it's kinetic energy better than a lightweight flywheel. Thus causing revs to drop lower faster. Realistically, good drivers fullthrottle shift, which negates the whole problem in the first place.

They're nice to have, but consider it when you're putting in a new clutch or changing out transmission parts.

thats exactly what i was talking about...

like i said im buildin the ls/vtec i started from scratch and just got an S4C trans yesterday and now it is time for a clutch pressure plate and flywheel combo... iknow im gona go with a 4 puck clutch and a dual finger pressure plate but dunno if its worth spending the extra money on a lightweight flywheel expecaily when i have a stock one on my shelf

the main purpose of the car is gona be for dailly driving and draging on the weekend and lot of people i know tell me exactly what you just told me

i jsut wanted to get some more oppinions on whether its worth it

Like stated earlier, do it when you consider a new clutch.

 

you planning on turbo'ing the motor later? if not why do you need a 4 puck? ls/vtec could use something milder thats cheaper on the wallet.

 

i have a d16 civic, and i put a stage 2 exedy clutch and an ACT liteweight flywheel in there and i can feel i difference.... my friend drove it and said it was quicker....so i don't know if it's just us, but i really like the response.

 

ive also heard they make more of a difference on d-series than b-series

 

i have a lighter flywheel on my stock d16y5 and i noticed a difference. it is easier to stall, but you get used to it after a couple of days. it definately drops revs quicker then the stock flywheel. i like it.

If I'm not mistaken, Dseries flywheels are heavier than Bseries flywheels.

If you have the engine apart and you want to fork the money for a flywheel, by all means go ahead. It's not going to hurt you in any way, especially in an N/A car.

 

Yeah, I would wait until you have to replace something in there, then do it. And while you're there, replace what's more easily done while the tranny is off. Flywheel, Throwout and input shaft are more easily done when at that stage. Save some trouble and fix anything that has potential to need to be replaced down the road.

 

Lightweight flywheels are good things because:

1) The less weight the crank has to turn, the better fuel mileage you'll get (theoretically)

2) The synchros in your trans will wear less when drag racing (if you're not power shifting).. the lighter flywheel will spin down faster, and your engine revs will be closer to the gear speed you need for the next gear... your synchros will do less work. Basically on a stock setup, you can shift faster than the revs can fall down to whatever RPM the next gear is... when you let out the cluth, your syncrhos slow your engine speed down to gear speed....

3) Rev-matching is SOOO much easier. If you're approaching a turn or a stop and are downshifting and rev-matching, the LTFW makes the throttle repsonse in neutral NOTICEABLY better... all you have to do is blip the throttle with the gas and the revs jump up to where you want them to match the next gear.. where with a stock flywheel, they take a bit longer to climb and is not nearly as easy.

 

1) Good for N/A. Too light for turbo IMO (rip through 1st and 2nd too hard)

2) It does drop faster but not like it goes from 8k to 3k in the next gear or anything. With an S4C, it'll still stay in VTAK zone.

that's one of the silliest things i've ever read. the only thing that i've read that is worse is the "LS trannies are better for boosted cars because you say in boost longer" LOL

a light flywheel will help any car. i have one on my car and have had no problems with shifting or idling.

and that is bad thing... WHY????

traction? you will not grip at all so if your going from a dead stop you might actually start driving in 3-4th gear depending how short your gearing is in what tranny you are using.


I have the jun 10lb flywheel with ctr n1 crank pulley and my car revs so nicely, I love the setup and would get the light flywheel if I had to re-do it

 

i have a 8 lb fidanza with a 4.7 itr tranny and i love that ****

 

i found a kid with a toda flywheel and i got a clutchmaster pressure plate but it needs to be resurfaced as does this flywheel i found for $100

now can you resurface a p/p and a flywheel or will there be clearance issues

 

i have a 8lb flywheel on my b16 sol and i noticed a huge difference but i also added a 1.5lb crank pully the stock flywheel is like 22lb or so and the crank pully is like 16 so thats alot of weight dropped and the throttle response is great i would never give up my flywheel..

 

I would do it

I'm going to do it when I need a new clutch, I hate winding it out and having to wait like a full second to let out the clutch in 2nd b/c the RPM's are dropping

You're right, because falling out of boost is the best thing you can do for a drag car.

Try again.

 

On my boosted d16y8 I have a act xtss and streelight (12lb) flywheel. I loved it before the flywheel the car felt so slow to rev up, after wards it felt like a f1 (not to dramatic but it was a big difference)

What the guy said about revmatch is very true also. I would not get another manual car without upgrading the flywheel and clutch setup.

On my rsx type-s the first mod i got after buying was a competition stage 2 clutch kit and act prolight (8.8lb) flywheel
The only thing is i wish is for the pedal pressure be a little tougher.

 

I spun a rod bearing in my b16 so im swaping blocks and I thought about since ill have it all apart anyway, just not sure i have the cash for it but would love to do clutch and flywwheel. should I get the stock flywheel resurfaced? or is it even worth it?
