whinning noise from engine bay

Spray a bit of WD40 on the belts and see if to goes away. Dont spray to much because it might cause the belts to slip. I usaly spray it on while the engine is running and stop spraying when the noise goes away. There is also a lub stick you can buy for belts, its like $2 from an auto store.

Although, i dont think that its your belts making the sound, as you say its only happening over 100km/h. Taking a guess it could be your gear box or something that is just making the noise because of the air rushing through.

I used to get a whining noise coming from the passenger seat,
divorce fixed it,
Good luck finding your noise.

yeah i think it is air rushing through the gear box,
and LOL!
also noise usually happens at night when really cold and driving, not on idle, rev it out a bit and the noise disappears

I didnt mean air rushing through the box, i ment air rushing through anything an creating a sound. Could be a bit of plastic or something.

Is the sound in every gear and would you be able to describe the sound. Does it get louder or faster as you rev?

Haha Kosta? Didnt realise it was you. Tellin you shiz you already know.

not the supercharger is it??

I would suspect noisy timing belt (ie done up too tight) but that you notice all the time, in every gear, and (obviously) it's related to engine speed.

try and figure out if the noise gets louder as you go faster (speed) or as the engine speed increases (rpm)
