while driving the R today i noticed a very quiet whistling type noise coming from the front end while accelerating slowly at 3500-5000rpms, then it goes away.

unless one is really listening to the car it is not noticable to the ear.

perhaps there is a post on the site already adresseing the problem.

could it be a bearing or something?

just wanted to see what it was before she goes into the dealership thursday

 

do you have a cold air intake?

 

just CAI and short shifter.

on one of the previous posts it said that it is just a minor problem if one at all.

i hope this is the case. what is your opinion?

btw wierd spelling for a weird guy.lol

 

That whistle is most likely from the cold air intake.. nothing to worry about.

 

yes i have that same whistle and it's from the CAI. I can actually nail it in the sweet spot and have it whistle at hot chicks walking downtown :lol:

 

Before you assume that it is definatley the CAI you should take a second listen or replace your CAi with the stock Air intake.

I am breathing thru stock and I stil have a bit of whistle...and it is subtle as hell...but once you notice it you cant ignore it. Its not the T/B and its not a belt.

Iv'e posted a few times about this..but havent isolated it quite yet.

The car is going to the stealership (still under warranty) to rule out any bearing ish. In the mean time, cut a length of rubber hose and hold one end to your ear and one end at the PCV valve. If that whistles swithch it. Rule that out first ($16.00).

Ill tell you what they tell me.

it's the intake, if you have a aftermarket filter that's a open cone shape, you'll hear that noise, it doesn't have to be cold air, it can be hot air, i have a hot air, and mine does that, it's just that when the air is sucked in through the filter, it goes in a swirlin motion, and creates that whistlin sound, it's perfectly normal, no need to worry, just think of it as a turbo, and your spool is boostin up, hahahaha.

 

I believe someone said something about a noise like this coming from the Clutch? It was in a post like Last week or something.
I kinda vote for the Intake being the culprate. I never noticed it on my Civic but since the R lacks the sound deading material I guess it's more noticeable

 

It's the intake. I had AEM CAI also in my car before. To tell you the truth, I think my car ran slower with it in, then with the stock air box. It ran even slower with the Bypass put in (yeah, it rains in California). Anyway, I put my stock air box back in, and love it. It's not nearly as loud (always a plus). I think at first, with the AEM CAI, you feel faster because you "sound" faster. I don't know if that makes sense to any of you. Good luck with whatever you do though.
