Faint whine sound under throttle?

Gear lash or whatever, no big deal.

Is this accurate? I haven't really opened the car up lately and when I did today, the car sounded like it was supercharged.

A slight whine came around 3k-7k thru my first 4 gears.

Only happened once or twice though.

Yup, I hear it all the time. I would suspect the reason some people can not hear it is their ears are not as sensitive to that frequency for some reason or another or their cars are loud as ****! Can't wait for my FI exhaust so i can junk this stupid OEM exhaust.

It's the intake. Low humidity days where the air is feeding perfectly into the manifold. It gives off a low FI like sound. It happens more often when you modify the intake.

i doubt it is the stock intake, the whine OP is probably talking about sounds like faint belt whine(kind of like a supercharger) that is coming from the rear drive axle and diff

intake noise is more like this(go to 29m41s)
