08 WRX squeak sound - Need help
Hello everyone, I have a 2008 WRX wagon with basically stock everything except for a Cobb intake and cobb downpipe and cat back exhaust. I use the Cobb accessport and have stage 2 with 91 octane gas.
My issue is, the other day I was driving and during 5-10psi of boost i heard a squeaky sound. 2 days later, it is random and is from 3-15psi. Usually it would start at 5 and around 8 or so it would stop squeaking and just be the normal turbo spooling sound. Currently, instead of the squeak dropping it continues to squeak all the way through the pull.
I have read it could be a clip on the tubing for the turbo, or the intercooler. I tried the water and soap test to see if there is any clear sign of a leak, but no luck with that.
About a week or two ago I put on new AC and alternator belts, I don't think those could be the squeak, but I have no idea.
Please let me know any thoughts of what it could be and any easier way of diagnosing by myself.
