Howling noise at WOT

[Donovan]

Ok so... is this a stuck turbo or a hose loose?

Howling noise at wide open throttle, and boost stops at around 16 vs going to 20.

MPT tuned, CVF FMIC, SPD DPs etc

Yep bet you lost bearings on one of them. How often do you change your air filter or clean air filter? You have to keep them changed out or clean especially on a tuned turbo vehicle . If your filter is really dirty you can over speed your turbos. Like putting hand over a vacuum cleaner speeds up.

Dude.

It’s wild that you said that because I was getting a code that said air restriction. Once I change out my air filter that code went away!!
Shortly after the code went away is when I started getting this howling noise!

Fuckery bro... how else can I check for a blown turbo? I got just under 50k... warranty still?

Since the noise started after air filter replacement, check to make sure the filter, air box, and tubing are properly installed/connected/sealed.

Certainly will do.

A stock tune accounts for dirty filters and keeps boost lower, with a tune its trying to attain 20 psi its going to open those waste gates pretty far to try and attain that psi. Turbine RPM goes to the moon.

I keep filters rotated out . New one when street driving , a used one not that dirty for playing in dirt. When that one gets too dirty toss and buy new one motorcraft amazon pretty cheap.

Yeah I’ve already replaced the filter that is what made my air restriction code go away. But I started having these issues after I replaced the filter

I'm afraid the damage is already done . Turbine is scraping the housing . Imperative to keep clean filters. It could be a bad BOV may be it leaking by . I would look at that before turbos.

 

[Donovan]

Ok. ****.

Taking the vehicle in very soon.

I will keep you updated.
