Weird noise on WOT

Rsoxs19 · 09-30-2017, 09:19 PM

Does anybody have any idea what this weird noise could be? I figured this was a bigger place to post this. Here is the link:https://youtu.be/VYK47Bj9lx0
Don't mind the CEL, never happend before but of course when I take a video it does. My vacuum line popped off to my bov.

It started after I installed my VRSF relocated inlets. Only happens when I hit high boost. My logs look good. I hit my target PSI so that's not an issue.

Checked all pipes from outlets to intake manifold and the clamps are all tight. I have no idea what it could be. The only guess I could come up with is the intake to my front turbo is sort of squished because of a bolt on the engine getting in the way. My friends say it sounds like a kazoo lol. I'm at a loss...... I want my turbo whine back... help. Thanks!

Could my HKS BOV be leaking under high boost?

Boost solenoid or dv like he said

yea they go bad and make noise sometimes. does the noise come from the passenger side (boost solenoid) or driver's side(bov)?

You're accidentally leaning on the horn

I've had friends ride in the car and when it hit boost they asked if I was holding the horn. Another said it sounded like a kazoo

When I'm driving it sounds like it's coming from the charepipe area but when I'm the passenger it sounds like it's coming from the inlets. I know that isn't much help haha.
