its not that lound and im not that worried about it, wondering what it is

 

turbo spooling...?? your descriptoin is pretty vague... what are you doing when you hear it?

 

yeah..probably turbo spooling, or accle t case whine?

 

sorry it not turbo spool it like a light whistle...well it might be the turbo but i notice it at low rpms

 

ya im pretty sure its not the turbo i noticed it when i took out my back seats
what is the accle

 

if you noticed it when you took out the back seats, it could be your fuel pump? is your car stock? did you buy it new?

 

fuel pump?

 

yeah don't worry about it I have it too. It's the fuel pump.

 

fuel pump makes since thank u guys

 

is the whistle noise there when ur idling too? cause i might have it too.. but seem like a exhaust leak also..

 

ya kinda but very very lightly more when im drving

 

I have the same exact thing. It is not loud at all. It usually is lounder when I just start the car (when the car is cold). Once it warms up its not as loud. It also whistles a bit under acceleration. Its not the turbo (turbo is much louder). I have been wondering about it as well. Could just be paranoia!!!

 

i don't know why but mine is bothering the **** outta me.... i know its there, and i listen for it.

 

its normal buddy..

 

You're going to notice more sounds, and even your service light always going on with all kinds of different codes . You just have to get use to it. It's just part of owning an Evo. BTW, I have that slight whistle on my car also. Enjoy the car and stop being paranoid.
