Squealing noise when accelerating above 4k rpm

[gedmisten147]

hey guys, i have a squealing noise when i hit full boost accelerating past 4000rpms, I have checked every hose possible and cannot locate the squealing, both honda and nissan could not find it as well, with nissan doing a smoke test on the turbo for any leaks, any ideas as to what this squealing could be? could it possibly be internal damage to the turbo? or a fucking loose/old belt, the car is throwing 0 codes as well making it more difficult to locate.

If not throwing any codes not too serious yet but definitely concerning. When throws a bunch of codes and/or kick it into limp mode then in trouble because have to drive around like grandma. The smoke test show no leaks?

Charge the battery (with actual charger or run engine with headlights on for an hour). Take off drive belt (17 or 19mm wrench for tensioner pulley). Take it on a short drive not far from home/wherever you took the belt off. That will cancel out belt and tensioner if noise is still present.

Smoke test showed no leaks which is what’s more confusing, nissan & honda both said the car is running how it should despite the noise, should I have it dynoed to see if they can find the noise location?

I'm guessing you ruled out the belt?

Yea a belt could squeal. I'd advise person to take into decent local mechanic.
