custom stainless intake

[infernosg]

I can see the concern. A rigid body fixed to another rigid body exposed to vibration is generally inviting fatigue due to cyclic stress. The question is whether the magnitude and frequency of the vibrations are enough to cause failure, which is dependent on things like material properties and temperature. My personal feeling? It wouldn't be too hard to incorporate an isolator between the intake and the body. Either way, worst case is the mount breaks. It's not the end of the world.
