High pitch noise at 3-3.5k under any thp

[dkrep]

wondered if anyone has heard of this or had the same problem. i am under the impression that it could be the intake sucking air but never heard this noise before on a NA car. Can you help me out with this

could be the intake sound...what type of intake? you need a picture of your intake.

The JWT popcharger has a heat shield made of metal. Mine whistles under certain conditions, but that is just the intake sound.

it is stock for right now.

take a few pics of your engine bay so we can tell you if its stock

could be intake, could be plenum spacer...take a look under the plastic cover between the upper and lower plenums for a spacer

again, take pics so we can tell if this could be the likely cause of sound

also: describe the sound more if possible and when it happens specifically

edit: here is a picture of Toddnos' popcharger install, take a look and compare somehttp://forums.g35club.org/zero...44331
