Loud Constant Noise From Engine Bay

[rsrsrs]

Took the car out last night, no problems driving, didn't drive weird or anything of the sort. I came off of the highway and then heard the noise from the engine bay. This sound is constant pitch and doesn't get higher or lower when I drove back home. Even when in neutral (6 speed) and revving there's no difference.

The sound seems to be coming from the driver side around the power steering pump area.

Here's a video of the sound. I'd advise to have your volume low

The noise continued on this morning as soon as I started up the car. Here's what my gaugse read after driving to work. Again, nothing out of the ordinary here either.




Here's a list of my mods

Cold Air Inductions CAI
Spiral Ported Throttle Body
Whipple Supercharger
Elite Engineering Catch Can
American Racing Long Tube Headers
X-Pipe
Gutted Cats
Borla ATAK Cat-Back Exhaust

The last mod I've done on the car was rotors this past weekend.

For anyone that helps out, thanks. I have a date this weekend and it'll be super embarrassing to have my car rolling up sounding like an emergency siren going off

Going to start with non mechanical advice first. Have you tried washing the engine bay, especially underneath. I know when I was younger Bethpage would dump tons of salt on the roads for no reason. Make sure theres no salt and or denbris on the belts or anything.

No I haven't washed the car on awhile since every time I did it would either snow or rain the next day. I have noticed shit ton of dirt & sand on the road lately. I'll hit up a car wash after work and get the under carriage washed and post the results afterwards. Thanks.

Take the serp belt off and run the car for a few seconds to see if the noise goes away

From the video it sounds like a vacuum.
Did you track your vacuum lines to see if anything popped off.

I've read prochargers cars sometimes have this issue
But this was a hand full of years back..
Blower forces air. So could of popped a O-ring or vac hose

Good luck
Keep us posted

Will check that.

UPDATE

Okay so I went out to look at the car again. Vac lines looked good. Finally decided to just give it done hard revs.... Sound died out a bit. Another two hard revs, sound gone. I didn't get a chance to drive the car yet but I will be in about an hour. Will update then.

Drove around for about 2 hours. Sound hasn't come back. Very weird.

Good deal..

Something on the belts probably dirt in between the grooves Im guessing. That makes it sound almost like metal on metal. Glad its gone so far.
