New engine sound that annoying me. It's a chirping/squeal sound that occurs only during the first spool of the turbo under load. By the time I am at the end of my street it's essentially gone and not reproducible for that engine cycle.
The sound is very similar to a slipping belt. It sounds like its coming from behind steering wheel or the driver's side vent by the mirror, far back on the firewall and not the front part of the engine.
It returns for the first spool of the turbos even after a short stop. If pump gas or run into the store for a few, it's present pulling out of the parking lot...engine still warm.
It's not present if I rev the engine right after a cold start. Not present if I baby it down the street. Very related to the boost gauge.
Could it be the turbo itself? Some kinda vacuum leak?
Belts look good. I tried belt dressing spray with no relief.
COBB stage 2, CVF titan IC, aFE intake. Clamps tight.
