Previous STi Owners, Please Help!
I'm probably going to get slapped for this question, but I'm going to ask anyway.
I have 8000 miles on my 2005 STi, and I've never noticed any "turbo whine," or a "pshht" between shifts, until this afternoon.
I'm noticing turbo whine at the top of 3rd gear, and all the way into 6th, even at a steady cruising speed.
It sounds like when an airplane is sitting still, and then starts accelerating slowly from the standstill to take-off speed. Obviously, the turbo whine gets louder as I accelerate.
The only reason I ask is because I've never noticed this within logging 8000 miles on the car. Is this "whining" normal?
Thanks!

I recently sold my 05 sti, with 25K miles on it. Half of miles were stock, half with cobb ap and a txs tbe with cat. Definitely more noticeabe turbo sounds with txs downpipe. It also was noticeably louder with windown down at low speeds vs windows up. I doubt anything has changed on your car, unless you have changed mods. Are you sure the whining isnt gear whine from the front diff?

I'm pretty sure it's not the gears, because they sound more like a "howl," than a whine. If I stab the throttle quick enough that it just starts to take off, I can hear it. If I put the car in "Neutral," and stab the throttle, I don't hear it.

Did you recently do any mods to your car? What you describe sounds like you changed the stock intake.

A buddy of mine who also owns an STi stopped over today, and he has an TBE/downpipe, and he advised that the sounds I was hearing were perfectly normal.
I guess that from riding around with the windows open and the radio up for 8000 miles, I just haven't noticed it.
Again, thanks for the posts, everyone.

There is another wonderful noise you will hear, but you have to be going over 100, up to 125 or so, it's a great howl/roar noise. I recommend you test this out, asap and routinely.
Oh and you need to go to stage two, night and day over stage one! Period. PM for any second or third opinions on set-ups, I did a lot of research/ride-alongs. FYI, my catted turboxs turbo-back passed PA emissions for the guy that bought it. He just swapped the race pipe in a few weeks ago, no boost creep issues either, but it is going to get colder soon.

Yeah bro deffinately normal. for ***** and giggles i would look at the air intake box just to make sure all of the clamps are tight. one of the silver ones that hold the box shut popped off on my 05'STi and made the sound alot more noticeable.
