Speedriven Scorpion intake noise problem

Hi to all!

I've got Speedriven Intercooler kit for my s600 v12tt w221. After installing it I have noticed annoying noise when accelerating hard at about 2500-2500 rpm/min. You can clearly hear it at this video:


I have asked Marcin, he told me to change blow-off valves on turbos and check vacuum lines. I have changed blowoffs but nothing changed. Have checked all vacuum lines many times - everything is ok. Boost is ok too - about 20.5 psi at maximum. All others questions to Speedriven was ignored.

Today I have reinstall all intercooler kit components one by one. The reason is in scorpion intake. Even with stock IC this noise is coming from both turbos. But stock airboxes suppress this noise completely. But when I install scorpion intake with 2 cone K&N filters noise is hearable. This making me unhappy - now I install all stock hardware back.

Guys with speedriven intercooler kit - do you have that noise? How to make it non-hearable?

Yes, it was wet on the roads and traction was bad.
This noise is not from intake. At this moment I have all stock hardware - ICs, airboxes, filters. There is no noise at all. When I remove one airbox (no matter left or right) and trying to accelerate with open turbo inlet I hear this noise clearly. After that I install one scorpion intake with K&Ns noise is still here. So I think that this is a normal turbo noise but stock airbox suppress it completely and scorpions are not.
