Hi there,

I just noticed my car has a whistling noise sounds like coming from the engine when I travel at a high speed and release the paddle.

It is not very loud but noticeable. very similar to the some truck engine, some high frequency noise, but I am pretty sure it is not wind.

Any idea?
thx

It's the air being released from the diverter valve ( think blow-off valve, but it recirculates the air instead of releasing to the atmosphere) and isn't anything to worry about. When you add a down-pipe, intake or bump up the boost via a tune, it gets louder.

He has a 2.5L from the looks of his sig. No turbo.

Oh, then ....you're fucked. Sorry.



**Honestly, I have no idea if it's not turbo'd.
