Pretty sure my FL5 does this too. The car in general makes a lot of buzzing sounds. I just kind of accepted it.I tried to replicate this today on my FL5. Are you referring to the way the engine vibrates in the 3000-3500rpm range when on throttle? You can feel it in the pedal and hear it in the engine note.
I believe this is the nature of this platform as this engine doesn't have balance shafts compared to the NA K20 from my understanding. It's less pronounced in Comfort engine mode but I think you'll get used to it.
Yeah- just like, as light as you can be on the throttle is what I do to make the noise consistently, between 3000-3500 rpm, regardless of gear. It’s like matching a resonance frequency at a specific rpm.I tried to replicate this today on my FL5. Are you referring to the way the engine vibrates in the 3000-3500rpm range when on throttle?

I seem to remember someone with an FL5 on the CivicXI forums experiencing something similar and was able to replicate it on another person's car. I'm pretty sure it's just the nature of the 2.0L turbocharged Honda engines in this generation. It hits a particular resonance where the engine is more noisy and vibrates more than anywhere else so it's super obvious. I wouldn't worry about it personally.Yeah- just like, as light as you can be on the throttle is what I do to make the noise consistently, between 3000-3500 rpm, regardless of gear.

LMAO, it's not a mid shift bearing as much as he wants to believe it is.Guy in my other thread says it might be mid-shaft bearing. Now I don't know what to believe...
It is truly annoying me now though. Literally the only thing I'm not over the moon in love with about this car... but it's an Acura, it can't be that bad.
I'm going to get it into the dealer though, see what they say.
Yep -- I can reliably produce this sound the exact same way, although I find it more noticeable around ~2k rpm, probably because there's less intake / exhaust noise to drown it out.Yeah- just like, as light as you can be on the throttle is what I do to make the noise consistently, between 3000-3500 rpm, regardless of gear.

I don’t know if I share your optimism, but if it’s normal I’ll live with it because I love the car. I think mine is louder than usual though. I’ll try to take a video tomorrow when I get the car back.Yep -- I can reliably produce this sound the exact same way, although I find it more noticeable around ~2k rpm, probably because there's less intake / exhaust noise to drown it out.
Pretty sure we are talking about the same thing now, based on your comment here.
I did a lot of looking in FL5 forums (and watched some FK8 vids -- maybe try to find a couple if you're really worried that your sound might be something different), and my unofficial conclusion is that it's the wastegate arm. It seems to be normal for this motor, and it's well documented on FK8 / FL5. At first it annoyed me; now that I've accepted it is normal (presumably) and gotten over the anxiety I had originally, I've kind of grown to like it. It adds a little character to the car.
