Strangest issue ever!!!!!

[FRslimmyjim]

Hey guys,
I was driving my freshly built 420a with 1200 miles and it started to make a noise at 2000 rpms. It sounds like someone is fastening up a zip tie really fast. It is very short and the noise doesnt keep happening. What could this be?? Any ideas?? thanks

Post a clip.

Does it do the noise In neutral
Do it when Only Hot, Do it when only cold
Check fluid levels for peace of mind..
Is it always at 2k? and does it stop at a certain RPM?
I would cut open the filter and inspect.

Whatv have you dont to it recently? Ie added boost etc..
