Lets play a game: Mystery Noise
Its
not any of the following:
Belt, or pulley related
Suspension related
Driveline related
Engine valvetrain related
Now, with all that there, what would you guess the kind of noise was? I don't need specifics as to what on this car is making the noise, just toss some ideas out.

Does it do it sitting at idle, revving?

Not at idle, you need to blip the throttle to have it make noise in park.

What did you guys check when it was on the lift? Any chance it could be a tiny exhaust leak?

Just checked clearance between everything and then Adam/BLS listened with mechanic stethoscope while I blipped throttle.
It could be an exhaust leak for sure, just isn't a very obvious one. No soot build up or ticking at idle.

Next question:
Any thermal part to it? In other words, if you let the thing run for an hour or so does the noise change? Just thinking pipe expansion.

Negative, it will do it when cold or hot. No change in sound level IMO.

Is it in any way boost referenced? Like it shows up under boost but not vacuum? Or the opposite?

I know you clearances exhaust. But have you checked intercooler and cold side piping to bumper and bumper related parts?

That says 'mechanical squeaking' to me. Something rubbing under the dash, maybe? You eliminated the ABS, right? Possibly the brake lines rubbing on something, or the proportioning valve?

Yup, everything is free to move without getting close to anything.

Yes, ABS is gone and prop valve is in the rear. I will start looking for loose things under the dash this weekend.
Keep the ideas coming guys, appreciate em

Sounds like the vent blower motor or possible tire out of balance.

Would be cool, but I don't think they would survive in my death trap.

No HVAC what so ever is in car. Tire out of balance is possible but does it in park.
