    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!

    What car have you driven came equipped OEM with the lightest flywheel?

      But it's also about the weight relative to the engine power and size. A 20lb flywheel on a 500hp car may feel lighter than a 10lb flywheel on a 140hp car. The 500hp car has a better ability to overcome the weight.

    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.

    • @M-t3ch
      @M-t3ch  8 місяців тому

      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.

    What caused your fx250 to explode? Do you recommend against it?

    • @M-t3ch
      @M-t3ch  5 місяців тому

      @RickySlickk Honestly, the answer was uncertain. It was put in backward on the first install, and that mechanic abused it on the test drive pre break in. It's kevlar, so this could have done it in. But it's also a cheap part, and Ebay tier quality control isn't always the best.
      I tried to get into contact with the manufacturer to verify that this could have been a fluke, but after dozens of attempts, I gave up and got the Valeo kit.
      If I were paying shop labor, I would highly advise against it. But if you are doing it yourself and are willing to gamble, go for it. It was a nice kit, and there are a lot of people that run it with no issues. I drove a 328 that had one with 5 years 40k miles, and it still drove perfectly fine.

    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.

    • @M-t3ch
      @M-t3ch  Рік тому +1

      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.

      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.
