Flywheel not balanced? Symptoms?

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?

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.
