I was talking to a friend earlier today, and he suggested that I consider that my flywheel may be imbalanced or the flywheel cover may be loose (If it is this, do I have to remove the tranny to tighten it?!).
I am STILL trying to figure out why my car sounds the way it does.
For those who don't know, here are the symptoms again:
- "WOBBLING" sound occurs in the higher rpm range (above ~4500-5000 rpm). This is the KEY sound/symptom.
- Only happens part throttle. Never happens full throttle (or 75% throttle).
- Is NOT speed dependent or gear dependent, ONLY RPM dependent.
I have not discounted a broken muffler or something vibrating in the exhaust system. But I have to say, it does not sound like metal on metal.
Anyone with ANY suggestions would be greatly appreciated.

Have you changed anything recently on the car??...when did this "wobbling" problem start??...do you feel something in the steering wheel??....or is it just a sound?
-
No, it's been happening for a while. There is no vibration in the steering wheel. It's pretty much "just a noise" coming seemingly from underneath the car (exhaust?). But I wouldn't describe it as a VIBRATION. It's definately much more like a WOBBLING sound ("wa-wa-wa-wa-wa...").
Unfortunately, I can't trace it back to any one thing that I did.

^He?s saying it?s not speed or gear dependent but RPM dependent. So I highly doubt it would be the tires.
-
Couldn't be the tires. I just changed my tires to Yokohama Parada Spec-2's like a couple months ago. I had the problem before that.

I now have videos with sound. So you guys can actually HEAR what it sounds like. Anyone interested?
I have no where to host. . . so I'll have to email the vids to whomever is interested. Just let me know.

I take back what I said about the 3/4 throttle. It does make the sound at higher throttle pressures, but I just couldn't tell before because I couldn't hear the sound over the exhaust note. It seems intermixed with the exhaust note though.
Also, at a dead stop, revving the car into higher rpm ranges, then holding the throttle there. . .the noise is still there. So the car doesn't have to be moving for the noise to appear.
I doubt that this will clear anything up, but hopefully it will help.

Cool! Thanks CivicR.
Hopefully "THE SOUND" will get some exposure now.

217,
I'm not sure if this is what you mean, but I've been experiencing a metal-on-metal sound for awhile now. When you mean RPM based, is it during throttle? For me, you can really hear it when you let go of the throttle. The higher the RPM, the louder.
As for location, mine seems to be coming directly from behind the firewall. It has been suggested that my problem may be the blades inside the charger. Is it possible your sound resembles a grinding sound?
A-dub

metal-on-metal? Man. . . I hope not. I haven't even really considered the blades. . . but that would be bad too!
Today, my car is getting its 90k service.
Tomorrow, I'm bringing it to the exhaust shop.
HOpefully I'll get some answers within the next several days, and I'll let you know.
