RWD/AWD flywheel weight!

[boost_boy]

I never realized how heavy the RWD/AWD flywheel is until I actully removed the one off 240trainee's motor. That's where most of the issues seem to come from. That thing must weight at least 25lbs. I don't know who makes a lightened flywheel readily available, but one surely wouldn't hurt.

the stock CA FW is ~13kgMine has been lightened to about 10kg.Jun make one, fidanza don't though.

NorrisDesigns does it on a core basis. They send you a light weight one, and you send back yours and your core charge is refunded. It's just a shaved down stocker though.

yeah sure is, that's what I have.

just get someone to machine it for you and get it rebalanced, much cheaper.

FWD CA flywheels are much lighter then?

[Jezz_s13]

I dont' know, I tihnk the CA18ET might be but it only has 6 bolt holes, not 8 like the DET.

Quote »FWD CA flywheels are much lighter then?[/quote] It is! Mine is now around 15lbs. You can actually use the FWD flywheel, just have to use the FWD pressure plate and disc.

Oh i know...when i took my flywheel out, i wasn't really quite ready for the weight and i only had one hand on it and i dropped that fat thing straight to the ground on 2 of my fingers. Hurt like a mother, swelled up nice too.

[biosehnsucht]

but the FWD pressure plate and disc will work with a RWD transmission then? whats the difference in the plates/discs, is it just something simple like an alignment pin or the surface area is different?

[Doogz]

Yes, i would imagine that the surface area is different and that would be a good reason not to use one.

[boost_boy]

It's just smaller in diameter and not by that much!

if you ever mill down a stock flywheel I recomend a scatter shield

I'll second that..Once you take the mass out of the flywheel (which is how the stock unit disipates heat) and thin out/weaken the whole thing they tend to want to shatter... especially used in conjunction with a heavy pressure plate or "puck" style disc...

I think Unorthodox Racing can/will make custom flywheels but its not a cheap service.. Jun is probably the best bet

[Jezz_s13]

I've never known a reworked std one to shatter, but I fully except it can happen, I guess it's a matter of being a bit careful and not hacking too much off.The more you can take from the out the better, less inertia.

and the higher chance it will explode and amputate your lower legs

[240 Trainee]

I like my legs the way they are!! I remember thaking out the KA244 flywheel, and being amazed how heavy it was. Who whould have thought that there would be such a difference between FWD/RWD.

The FWD ca18de has a thinner and lighter fly wheel, clutch is about 1/2 inch smaller than the DET clutch as well as the pressure plate, But if you guys think about it for sec and ask yourself a question.

Nissan got the ca16de, ca18de, and ca18det, all were available in Japan, So why didn't they use the ca18de flywheel on the ca18det engine instead of the ca18det flywheel.

They got engineers that calculates every single detail in order to get the engine to perform at its best, Yes the ca18det flywheel is heavier and it might give you a bit of lag on lower end, but when this engine revs a bit, the heavy flywheel will make all the difference on top end.

At least thats how I look at it, Plus I don't want no one drilling holes in my flywheel, as you guys mentioned it will make it weaker and I don't plain on losing my legs or hearing of some one that lost their legs, my buddy got 5.0 Mustang and if it wasn't for the shattered plate, he would of lost his legs last summer.

Well, both my flywheels are machined and I've crashed numerous times, raced, revved and took the thing back to my clutch shop to see if it needs to be machined and he always tell me, you must not really use the clutch that much (Like hell I don't). The clutch material is the key here. I use kevlar which is a lot less stressful on the flywheel's surface than brass or copper composites. I've been using the same clutch face for nearly 3 years and it has barely worn; and can also hold 300+whp without shaking my car to death.

haha, mine is brass/copper im thinking, it doesnt like to be slipped much but i have gotten it so my passenger doesnt know ive changed the clutch at all. you can get used to pretty much anything if you give it a little practice. as far as a lighter flywheel, i would love one but with all the heat i know this new clutch creates i dont think it would be the safest idea.

i too would like to get my flywheel lightened while the transmission is out, what kind of shop do you recomend? and how mcuh do u reccoment sahvving off? say its 20lbs stock, shave it down to 13?? 14?? 15??? 10?? tell me what you think? i dont ever expect to go over 300 to the wheels! simple nad reliable!
