10:45 My dude really just called his ankle a “footwrist” Lmfaooo🤣
Wait, is that the ankle? ☠️
Thanks, I think you solved my noise issue.
Lighter flywheels do produce quite a bit of sound. I hope yours isn't too bad lol.
I got a lightweight flywheel and I thought I put the flywheel in loose 😭😂😂😂 I’m happy ur chatter sounded similar to mine bc oof I didn’t wanna have to pull it again
Haha yup
Nice video, sir! I’ve learned to love my chatter 😂 Excited to see what it feels like stock.
Similar haha, but more heavy footed gas input.
Are you using the Valeo single mass flywheel conversion kit? i'm considering it for my e46 330ci
Yes, that is the kit I bought. No complaints with it. Everything seemed to be quality.
Just make sure to give it a good break in period. It is made for the 328i, so I am not sure how well the material will hold up over time to the extra torque the bigger engines output.
Which Valeo kit did you buy? The E36 Valeo kits I see online aren't actually a lightweight flywheel. Stock is 27lbs and the Valeo kits have 26lbs.
I might have had my numbers slightly mixed up. I bought the Valeo single mass conversion kit for 328i models. Not a lightweight flywheel.
I did so for simplicity. I had heard from the NASA Spec 3 guys that the new production LUK dual mass flywheels have a high failure rate on track. Since I am planning on track use, I didn't want to take the chance.
i wanna fit a valeo single mass conversion kit on my e34 520i but im worried about that chatter or weird noises.
There is more than stock but it's very tame in comparison to all of the other aftermarket options.
Noise is only a factor in the drive through with the A/C on. I just hold the clutch in when I'm talking to the person. People are annoyed by too many things that don't matter. Learn to shift? Tap the throttle and release the clutch as the RPM'S come down. It's not the car.
Yeah, it's not as bad as people think, in my opinion. The more raw driving experience is more fun in a performance setting. The FX Stage 2 kit particularly wasn't too bad, nvh wise. I'd run it again if I could count on the clutch not exploding, lol.
@@M-t3ch I've had a UUC M5 version that was pretty good except for the clutch pedal effort. I was the loudest. However, I've been using the JB Racing for 15vyears or more and even sent it off to have JB Racing install a new wear surface ring and it was like new again. It also uses the stock M3 clutch disk and PP so that is simpler to source. The setup is the best overall in my opinion. When I drive wit it, you can tell it's a lightweight just by how I use the throttle to control it. It's like playing the trombone I suppose. When everything is done right there are no downsides. It's all fun and I couldn't imagine driving without it.
@williamrogers4914 That’s a cool perspective! I bet having the stock clutch pedal weight helps. The FX kit had a heavy Kevlar clutch disc that was not fun in traffic.
I'd be curious to see how your setup feels. Given that you run the non sprung M3 disc, I'd think the engagements are harsher. Are you on rubber diff bushings, motor mounts, and have a clutch delay valve?
@@M-t3ch No clutch delay. I thought I had a stock M3 disc but I also believe it is sprung. Information on BimmerWorld says all new design is using M5 sprung disc so now I'm confused.
@williamrogers4914 Maybe someone else will chime in. The M5 disc would make sense. It would help with vibrations.
Either way, I think it's cool that you daily the setup!
I’m putting a clutch kit with almost 20lbs less weight in my Veloster N here soon, so I’ll have a good time there.
After starting to daily my Honda CB500X, I really started looking at the car as a lethargically shifting car (it always has been, but context made it worse).
Wow, that is extremely light! What is the weight of the stock clutch kit?
I've got a 97 M3 coupe. Couple years ago I pulled the engine and trans and did a rebuild on the S52. Put a new stock clutch in and opted for a JB lightweight flywheel. I like the lighter revs....it's nice and responsive. But the trans "chatter" does get old quickly. If I could go back and do it again I'd go with something closer to stock to avoid the noise.
I guess it all depends on what you're after. I was planning on turning the car into a weekend track toy ...still may do that but the car is mainly a street cruiser. I've also got a Dinan "stage 5" setup that gives it a nice increase in power. That includes a 3.5 bar fuel pressure regulator, 3.5 MAF, Dinan intake and throttle body and the M50 manifold. Paired with a Dinan tune, it does pretty well. I was going to do the Schrick cams but there is mixed info on whether that is worth doing or not. The head seems to be the choke point.
I agree, I'd do it again on a track car/weekend toy, but this car sees a lot of traffic and daily driver duty. I prefer the stock weight in that application. I wish someone had made a 17lb flywheel. Close to stock but not too chattery or compromising as a nice medium.
As far as your cams go, this car I drove last year with the Turner Stage 4+ setup and a ported head. Felt a lot quicker than a stock s52. The Turner tune is pretty conservative as well. I think there was more in that setup to be gained. Low-end torque was noticeably worse than a stock s52, but I'm sure you already expect that.

Have you guys ever ran your lightweight flywheels with lightened crank harmonic balancers and noticed reduced chatter noise would love to know if that fixed it for you guys
@@akeelshah7904I have not. I didn't even know they made lighter harmonic balancers. But that's a very interesting concept.
I'd think a lighter one would make noise worse.
Such a weird looking Miata you have here. Glad it's getting better!
E36 Miata in full recovery 🫣
She pulled good but that misfire tho
That happened after this was shot. More on that soon...
