Well I installed this intake today. All else if fine in any other rpm but when im on w.o.t at high rpms I hear this roaring vibrating sound. Like a can of bees but not exactly.

It will kick in about 6,000 or something odd rpms and will rise with every rpm. Theres no loss in power but it is very noisy.

 

Im not surprised theres no answer, all my searching has led to countless threads with no answer to this question.

I hear people blame octane (not the issue)

I hear its due to ports opening and what im hearing is resonance noise.

 

Angry rotary bees!

If you look at the stock intake there is a resonance chamber attached to the accordion section. I have a feeling that this is there for a reason.

you are probably hearing your vdi working.

 

This is one intense transition.

 

take a video?

 

I have this problem at the moment as well. Happens at high revs on WOT but if I smoothly go through the revs its fine. Hoping someone can enlighten us on this problem.
