edit.

that is really loud, sounds like a vacum leak, take off the upper intake and look in the ports with a mirror to see if there could be a gap somewhere.

Did You ever find out what it was?

I have the same type whistle with my BBK 70 MM and TrickFlow Street heat intake. It sounds more like it comes from the intake. I too went over the vaccums a million times.


As for the guys who mention bearings?? listening to the video Clearly would tell you its not a bearing sound.

Its got to be something with these trickflow intakes.
