it's doing it while drifting as well.
even at high rpm, if it's set to stock boost, and the BOV spring is too tight, then it'll do that. stock boost is the same as our cars. around 7psi.

That s14 aswell as many high performance turbo cars will have an external wastegate and thats where that chatter noise will be coming from, on the other hand the noise can also be acheived by the air passing back through the turbo on such vehicles as ours only it will not be as loud and only really happen at low rpm as this is what i get.
 hope this helps.

really? external wastegates do that too? I thought it was only wastegates with weak springs.
learn something new everyday

.Yep Adz is right.......plus, My external wastegate chatters like that as it regulates full boost aswell. It sounds pretty hectic. Although it doesnt do it at the moment as my silicon hose still isnt here and my turbo is screwed. £425 FOR A NEW T3 FROM TURBOTECHNICS btw
