Mine makes the noise at 80mph and 3k rpms in 6th. I'm a big fan of it.

past

 

the whining/hissing sound at 70mph ain't normal.

 

I just got a 07 nismo Z.. and I noticed my car also makes a whistling noise at 80 mph and above.. I am not sure what it is.. it is slightly annoying.. but I don't think that is anything harmful..

 

Mine makes the whirring noise from the rear at about 80mph and 3000k in 6th gear... Just doesn't sound right to me...

 

close your vents or get your weather stripping re-done....i had to get new weather stripping done on my passanger side window. (nissan warranty'd it.)

 

Check weather striping under hood near front window

 

ur car is stick right?

i have an 04, and its not ur tranny.

does the sound come from the right side of the car? kinda low?

 

I have an 03 and the car is completely sound and quiet from the inside.

 

if its what i think your taking about it goes away as soon as you give it more gas or completely let off the gas. I have that same noise and it does it when you are still kind of on the gas, i'm pretty sure it happens from the diff not having any sort of load on it, neither acceleration or decceleration but everything moving in perfect synchronization. i think that because it seems like the noise comes more from the rear of the car.

 

LOL " HwinG~" Imo it doesnt sound like anything major.

Say for maybe "Ka-boom" "Wee-Blamo" "Wa-Bang"


Serious tho doesnt sound like anything out of the norm.

 

Yeah, it comes from the right side kind of low... And goes away under acceleration or off gas completely, slight on gas the noise stays...

 

lol
