Small whine after installation of cone filter

[agarc023]

So I just replaced my stock airbox with a K&N filter and air box (like the one below).

When I'm driving along and let off the gas there's a small whine that can be heard from that area. A friend told me that it sounds like I have squeaky brakes, but I am sure that that is not it since I don't have to step on the brakes to hear it.

Besides the air filter and a ucip, everything is stock. Anybody know what could be causing it or is that normal...it's starting to get annoying.

Take off your intake pipe and check your turbo's compressor wheel.

I checked it but there is no shaft play whatsoever and it looks fine. Any other suggestions?

That, or do a boost leak test.

Thanks for the reply's. I'll get that done this Friday. Kinda sucks though if it is. The whole reason I bought a 1g bov was to eliminate the leak

That's not my picture. It is the one off of Turbo Garage's website. I just put it there as an example of what kind of box I had there, but I do have a 1g bov.

Yeah but its not the sound of spooling thats bothering me. It's a little whine after I let off the gas (and after the bov releases back to the intake). As soon as I get back on the gas, even lightly, it goes away.

Bet it's the blow off valve. Open intake makes it louder, mine does the same thing. Not a big deal.

I'd say the same thing, open intake lets you hear more things going on.
