Hi all, this is my first post here. I bought a 2008 WRX sedan (no mods at all) about a month ago and have been loving it. I'm looking forward to the first big snow dump to get this thing in the mountains.
One question - in the last couple of days I noticed a noticeable sound that I haven't heard before. It started when the weather got cold in the mornings (low 30s), but lasts throughout the afternoon (mid 50s). This could be purely coincidental, but thought I would mention it.
When accelerating past 3k rpm and the turbo kicks in, I hear a very loud and noticeable "whooshing" sound. It lasts until I shift or let off the gas. Closest description to the sound I can come up with is trying to blow out birthday candles as strongly as you can. It's a clean sound, no pinging or scraping, but loud. I can barely hear it over the stereo, but definitely hear it with the stereo off.
Is this normal? I checked hose connections under the hood and things looked alright, but I'm not an expert and wasn't sure what I was looking for. I mentioned it to the dealer during an oil change and he kind of blew it off, saying it was normal. But it didn't sound like he was really listening and didn't give me a lot of confidence. I'll try to post a video on the way home from work.
I appreciate any advise!
