Hear BOV at low rpm but not at high rpm
In my stock 2003 evo, I hear a faint BOV sound at 2.5k RPM but not at 4.5k. Can any knowledgable EVO person explain why I don't the BOV at higher RPM? 
I thought the turbo only spools after 3k.
I tried a search but I didn't find anything.
Mods, please move this to the Newb/FAQ Section if you want. I just wanted more exposure to this thread. Thanks.
