My first guess is there's a vacuum issue that needs to be found.

get a can on Carb Cleaner and spray a small amont on the connections of all the vaccum lines and hoses if the RPM rise you found your leak!

left side under the hood...it seems like it's only making the noise when the starter is working. hmmm....i don't know.

it doesn't make noise after the car is on, even when going speeds of 200kph...

i figured if it was an intake hose leak it would get increasingly louder as speed / rpm's increase.

i can't help you if you cannot sdescribe properly:
1) your first post sez: "when u turn IGNITION OFF..."
2) now this post sez... "only when starter is working..."

that is 2 entirely opposite events.

and then speeds of 200kph???
