After missing my tuning session due to family issues, I finally got the UP, DP & 2.25" axle back on the Legacy GT (05) along with a Perrin panel filter (silencer removed).
After install, I let the car warm up at idle so I could check for exhaust leaks. There was smoke coming up from the lower engine compartment, but it did NOT smell like exhaust. More like belts being broken in or rubbing somewhere... but I checked all of those and found nothing.
So I took it for a test run, first taking it easy and then getting on it. Impressed at Cobb's Stage II map I was. When I parked the car, let it cool down for a while and then restarted the car, the smoke was non-existant! :wtf: It hasn't come back either!
The spooling of the turbo is now more pronounced (as expected) and I can hear the BOV much more clearly as well!
The noise I'm not familiar with is as follows:
During moderate to heavy acceleration under load I hear this sound that can only be described as somebody telling you to be quiet by putting their finger across their mouth and making the noise "SSSHHHHHH" but only much louder and more coarse as if it's a demand more than request. Almost raspy!
When I let off the throttle, the sound disappears and I can hear the BOV doing it's duty.
At certain points (haven't pin pointed yet), this noise will come on during the moderate AND heavy acceleration, but it will only stay around up untill a certain RPM range (higher) and disappear! Then... again, it's the BOV when I let off.
Note: This noise cannot be heard during free rev in neutral, which has made it VERY difficult to pin point. Only in gear during throttle application.
Any ideas, experience or input are greatly appreciated!
