too light of a flywheel

[zombieslider]

is there such a thing? Someone on my local forum has a 9lb flywheel up for sale and i wanna get it but is that to light for the ca? I know itll def affect the low end tq

Can't help you with the fly wheel but you're close by me. I live in alpharetta off state br.

you have to be careful, there are def drawbacks to light flywheels. you need more throttle to launch, your revs will drop very fast between shifts. You may also have stalling issues when in neutral. I put an 11lb in my fiancees 03 tib, alot more acceleration but you have to be alot quicker on the shifts. you can feel the lack of power in the motor from a dead stop.

Stock is 27lbs, my JUN is 11lbs. It makes a huge difference. Once you become accustomed to it, there really is no negatives to it. Is it an aluminum flywheel, or a billet steel one? Who makes it? I've never heard of a 9# for a CA.

Yeah....never seen a 9# unless it was a custom piece with all those huge circles drilled into it.

Do you have to tune for a lightened flywheel?

Ive never heard of that but a quicker spooling turbo might help with driveability.

you won't see 1/10th of a hp gain on a dyno, or 1/10 of a second lower et, with a light flywheel....for whatever that item is worth to you Sure it affects the way a motor free revs, which mean nothing. You can only accelerate in gear under load.Our starion oe flywheel weighs 36 pounds. 11 pound alum unit... zero difference in perf.Under 'lab' conditions, I suppose one could prove how a 25# lighter vehicle improved

I'd only buy one of those XTD clutch/flywheel packages, for the good value,and the convenience during installation. Weight reduction of the lighter flywheel(=lighter car), being the primary interest. After all, that is whole idea behind putting the CA18 in a corolla

[themadscientist]

It affects the way it revs in all situations. My CA18DE with the Toda flywheel was a formidable motor when used correctly. It would wind out under a load much quicker than stock and acceleration improved. Conversely, it was a complete dog from a dead dig and I had to launch it at insanely high RPMs because a heavy flywheel can store the energy to explode off the line and the lightweight can't. I always raced the car from a roll whenever possible for obvious reasons and had to keep revs up a bit higher to keep the power there. If you can stay above the falloff point and bang your shifts right the lightweight is in its element on the track or highway. For a street-driven car it is a big sacrifice in driveability and while I was willing to accept that most find it annoying. There is a reason different motors have different weights of stock and lightened flywheels, each likes a certain weight to achieve the right balance and store enough force with as little weight as possible. Like anything, there can be too much in either direction. 9lbs sounds too light for anything but a track car with long straights and high speed corners.

Do you guys feel for troubling noises coming through your drivetrain with a lighter wheel? I have only driven a few z's and a bimmer with both a stock and a light wheel, the z' felt much better to drive but the bimmer had trouble stalling out unless you hit it like a drag launch every time, plus it felt like the motor was over-revving when close to the top. I was thinking too, wouldn't full boost come on later with less mass right there closest to the crank?

The biggest difference with the lighter wheel I like, my z would never break traction coming out of turns after I changed out to the light one. It seemed like the car kept some power from the wheels over a longer time but managed it better.

My old CA had a Toda flywheel and 6 puck Exedy/Diaken single plate and was a blast daily. It would be tricky to drag lauch sometimes, espcially with low traction/worn tires. I now run an OS Giken twin plate with their lightweight flywheel (sold as a combo) and the match of low mass and 2 friction plates means unless you are used to it, do not expect to lauch clean. I still have trouble if I drive in flip flops.

The moral is a light weight fw is great, but takes a bit of learning to drive. I think that a 9# fw would be extreme with a grippy friction plate, but you could learn to drive it.

[themadscientist]

The twin on my CA18DET is great. The only trouble is when I get in another car and stomp the clutch pedal through the floor.

[rico05]

Awesome. It's pretty rad when someone like a state inspection tech or a buddy tries to drive my car for the first time.

Start car. In gear. Let out cluth. Dies. Repeat.

wow this thread took off, its actually a cusco flywheel for an SR he said it was chromoly

[zombieslider]

slow325i your on 240atl arent you, im vqdreaming on there

To everyone else ive had a light weight flywheel on my ka for almost over a year little things like that dont bother me while daily driving it mixes things up and makes it less boring to me. I guess from what im reading im gonna go with a little heavier flywheel

[IggyEGuana]

dont think a chromo flywheel is gonna be 9lbs. Mine is a Fidanza alum for SR and is a dead 9lbs. Advertised as 9.5 but its actually 9

[zombieslider]

thats what cusco advertised it as 10.5lbs not just what the seller is saying. Anyways i ordered a xact street lite it should be 12.5lbs so thatll be a lil better but i havent decided what clutch i want to get

[boost_boy]

I caution each and everyone of you to judge for yourself about what the benefits of lightened rotational mass would yield for your CA18 set-up. My opinion or experience more than likely would not benefit most of the RWD guys because my cars' configuration is FWD (except for my 240). I have changed from a stock twenty something pound FWD flywheel to a stock FWD flywheel that has been stripped of 5.2lbs and the results are noticeable ( I think), but not by much.

If your car is tuned like crap or runs like crap or just don't even run, then obviously adding a lighter flywheel is near pointless. So I say to all, get your car/engine running and performing the way the engine is supposed to and then you can gauge what upgrades might benefit your future goals.

im going to say what i always do. Keep the stock flywheel. i would never run anything but stock. lightened flywheels are asking for problems... especially aluminum ones... the slightest imperfection in the wheel, can become a crack over time and BAM! it flies apart and destroys everything in its path

[zombieslider]

well i never had a problem with the fidanza on my ka

[Warped161]

i have also never had a problem with my fidanza flywheel. boost_boy you know there is a big difference between a lightweight flywheel and a lightened flywheel. Just removing the mass is not nearly as effective as the flywheel being light at its core. there can also be structural integrity issues.

Thanks, but I already know as I have two other sentras with HKS flywheels in them as well as gang of other g-fast goodies. The trimmed flywheel on my car has been around for a long and after recent inspection, it appears that it will be around for an even longer time.
