i donno im a newb, i know different BOV's have different sound but im pretty sure it depends on how much air is being pushed by the turbine (the higher the rpms its spinning) and I guess the psi associated w/ it (pipe size?). when the throttle is closed the air thats comming from the still spinning turbine is released into the atmosphere through the BOV, untill the turbo slows down, or the throttle opens up again allowing the air to go into the chamber. So if the psi is high when the throttle closes the air will be forced out harder? I also am pretty sure the BOV is vacuum actuated.RSik_C said:damn its so loud?
so heres the question.
wat makes sound so loud? dose it depend on the BOV or the size of the pipe u use?
RSik_C said:yea but i get that whsilin sound from intake its when suppose i move the gear from 3rd to frist all of sudean u hear this whislein sound but no i'm sure its BOV.
the thing is when u drive at high RPM it should make loud whislin noise right?
