Noise when accelerating in 4th and 5th gear
Well let me start off letting you know what I have. I have a 2011 WRX hatch that has a Ultimate Racing CBE, Turbo XS 50/50 BOV, and accessport stage 1 tune. Now to my issue.
I am getting a kind of whistling/whining noise that is most noticeable in 5th gear when accelerating from 60-80 MPH. It can also be heard in 4th gear when accelerating but isn't as noticeable. I haven't been able to notice it when accelerating in 1st, 2nd or 3rd. As far as I can tell, it sounds like the sound is coming from the front of the car. I though it was the turbo when it was spooling up but like I said it doesn't do it in every gear.
This issue just started in the last week. The car now has 12,xxx miles on it. (All highway) The car run/drives the same so I'm not terribly concerned. Yet.
