hi guys well last night i was driving back home from work , as i was driving i started hearing whining noise , it sounded like as if i had a supercharger, this happens between all gears from 2500 rpm and up , i usually shift at 3k , so my question is . (is this a common problem with the 2003 g35 coupe 6mt)please let me now . i have checked all belt because i thought something got loose , but every thing seems to look good , nothing loose , thanks in advance for your help .
FYI MY CAR IS STOCK NO MODS

 

mine makes that noise, buts its fi.

check your belts.

 

Its the stock supercharger - its in the glove box.

Sometimes if the tires are not wearing properly you will get a whining noise, might want to check your front tires to see what they are wearing like.

ah k great idea , i will try to look at it tomorow and possibly try to get an aliment just to be 100 percent sure is not the tires.thanks for the help

 

mines has been doing the same thing, but it's when I turn on the AC

 

Sometimes I hear a whining noise coming from the front of the car when I'm on a date with a chick and the windows are down so I can hear the exhaust note... but I'm pretty sure the whine I'm talking about is coming from the passengers seat area.

 

Maybe she is farting the whole time?

-Sean

 

Naw man it's definitely the stock supercharger...

 

I've noticed that whining sound and it correlates with rpms.
It's my gearbox and read other ppl with same sound from gearbox.
Mine hasn't gotten any worse, so I'm not worried. If it becomes a problem or worse, I have my warranty.

Yeah...lol...it does sound like a mild oem SC...lol

 

It sounds more like a power steering pump issue.

i will trade my g for urs

 

Not discounting your thought, but wouldn't a power steering pump wine at all rpm's? Like even at idle and wine sound change when you turn your wheels?
Of course rpm change as well.
OP said his whine starts around 2500rpm and up. Thats where mine starts to whine and its my tranny

 

hmm....sure. It was just a throw in, as my wifes car had a similar thing happen and it turned out to be the power steering pump issue.

What kind of whine is it, OP? High pitched, low pitched, and vibration with it? Does it get louder as the RPM's raise, or does it go away? I've seen balancer harmonics/crank issues do the same as well. Could also be a differential issue, bearings, trans, etc.

i think i have the same problem...it just started...it rattles like he said around 2500-3000 rpm's .....i dont know if its cause of the air conditioning or what?...i also need help!...
