Intake Whistle

I got a cheap intake off ebay for my gf's 96 civic LX, and it makes a really annoying whistle at mid range throttle. If i give it lots of throttle it sounds fine, but many times when we are just cruising in traffic, or accelerting after a light about the middle 50% of the time in each gear it whistles.

The stock intake had the filter on top of the manifold with a pipe going towards the headlight, this pipe sat on a big empty box, the box had an inlet and exit to the main intake pipe. im assuming this box was for sound dampening?

is there any way i can get rid of the whistle while still using a high flow intake?

Not really. The whistling is the turbulance of the air moving through the filter and through the pipe. Only way to get rid of it is get a different intake (may not cure it) or get rid of the intake. :sly:

I was thinking the whistle was comin from the air moving through the throttlting valve (not sure on correct terminology?) because it seems to only whistle and certain throttle positions

kinda like air blowing out of the whistle on a tea kettle, when the velocity gets to be high enough for the given flow diameter/area, the whistle occurs, could be wrong but that was my original hypothesis

The whistle comes from the angle cut port in the throttle body and has nothing to do with the pipe, filter or anything else. It does it with the stock air box and that is why it is positioned to muffle the sound. I removed my throttle body and smoothed the sharp corners and it doesn't help. There is no way to eliminate it that anyone knows of yet. That sound is annoying as hell and pushes me closer to a motor swap everyday.

just keep saying to yourself, "Oh, thats just my turbo spooling up..."

That's the air rushing into throttle body. Not much you can do about it. I get it too on my 96 dx, but barely, i didn't like the sound so i did some custom modifications. So unless you want to upgrade your throttle body or intake manifold, get used to it.
