Ever since the nitrous install (1 week ago) I have this annoying noise from the engine bay. At idle, its a slight vibration/wooshing noise and if you rev it up it kinda increases with the RPM. In gear, it completely goes away while the engine is under hard acceleration but comes right back once you let off the gas or the clutch. When I am driving on the highway in cruise, the sounds turns more into a rattly vibration and stay constant.

now, the only things put on the car were the 2 selenoids, wires, braided lines, relay switch, and tapped into the fuel rail for fuel. All the nitrous lines are zip tied down so its probbably not the lines rubbing or anything.

This is really pissing me off and I would like to get it fixed!!!

 

The beginning of bearing failure?? Do a search. Never had one, but have seen others use those same words. Hope that's not it though
