Yea, it seems that it might be normal. I just don't remember hearing it in my other cars.

I'm experiencing something similar. It only happens for a split second while under part throttle at just a hair over 3k rpm and it sounds like its coming from somewhere up front. The only mod to my car is a K&N drop in air filer so intake whistle could be a likely culprit.

My engine bay is completely stock, including the air filter. It happens both with and without the cover.

Same as above, stock car with a high pitched metallic sounding ringing/whistle on part throttle - 30-40% at a guess. Definitely coming from up front which made be wonder if the throttle butterfly is needing a clean down. No other idea what could be resonating so I'll be keeping an eye on this in case anyone cracks it!

Have a k&n and get this too. Definitely intake whistle

jkelley

Same. Learn to enjoy it lol.

Funny, because this morning I heard this same exact thing at about 25% throttle. Just a high pitch noise until you release or push the petal further in.

I can attest that I hear the exact same noise - perhaps a little more noticeable when the care is at 2 bars/just warming up & under load.
I have a drop-in K&N, tried with cover off and on; seems to be natural. Good to know others have the same noise.

Not a belt / pulley issue?

Get a louder exhaust to compensate?

Might be intake whistle. Try cleaning the throttle body. I had that same noise and it completely disappeared after a thorough cleaning. Only costs about $5 and 5 minutes, so might as well try
