If you are getting that noise at cruising speeds... Check your transmission fluid? Mine was low from the factory.

Default Ic Hose

Its definatly and I/c Hose twice once when i was racing a 350z at about 100 i just lost aloot of power... and every time i would take it over 3000 rpms the noise would start Especially at 4000 rpm when the turbo is already spooled up. IF its making that loud of a noise its definatly the I/c Hose check it out... im sure youll be just as surprised as i was... it could be off just a little and make a hell of alot of noise

Does it happen if the car's not moving and stationary? Does it only happen if the cars moving? If you were to further isolate the noise would it be toward the front or rear of the engine compartment?

I would definitely say check all your Intercooler Hose clamps between the intake and the Intercooler, and then check the ones between the intercooler and the turbo. It really sounds like a boost leak to me. At high speeds like that you could have been boosting alot of pressure and had a clamp slip off. If that's not it something may be wrong with your By Pass Valve (BPV) If you take the hose off on the side of it, you can see the cylinder, if it looks open, it may be stuck.

Any way you look at it I bet your still under warranty, so I'd just take it in and make the dealership do all the work. Afterall you bought it from them for a reason.

It's making the noise because you did it on Rt. 8.

j/k, I grew up in Oxford, and I don't miss Rt.8.

That actually sounds like the noise from the mirrors. On a day with the right crosswind, my WRX sounded like it was honking the horn, or like a guy with asthma was playing a harmonica.

i don't think it was the brakes. i'm pretty sure it was in engine compartment on the driver side. but the sound could have been throwing itself that high of a speed.

when i was hearing the sound afterwards, it wasn't nearly as loud. but i could make it out coming from the drivers side compartment. i really do think it was the boost getting stuck and eventually freed itself from daily driving.
