Strange Sound on Acceleration.
Recently started hearing what I would describe as a "raspy" and loud sound coming from the passenger side of the engine on acceleration. It only happens at lower RPMs while heavily accelerating, but all of a sudden goes quiet once above 2k ish rpms. Does not occur at slow acceleration. Any ideas on what this might be?
