Whistle Sound Question.

[wjfk32]

Greetings:
Last week i picked up my dorve it for the 1st time in 9yrs..All was good etc..etc..
I got my sis to start my car-today...(will be out of town till end of MAY--3.3 turbo engine-modified-euro-headers,no/cat-open k&n-7006-sc cams-msd 6al & coil.NGK racing plugs mag.wires,b&b dual exhaust/1bar...etc..etc...

She said it started in a second....She was surprised!....After talking with her, she noticed some whislting sound...Described as take your finger going around on top of a wine glass....She checked for connections of the wastegate--intercooler & wur connections all looked good.......

I did ask her if she confused with the msd sound inside the cockpiet...She said no...

Any suggestions or ideas....I have the airbox open/modified.

Anybody here there tubo-during idle??? or mix of burble-whistle & exhaust music??

If you look up "Porsche 930 exhaust" on you tube you can hear it whistle.

Some cars it is really obvious...others not so much.

See if it matches the noise your speaking of.
