I was wondering if you honda guys have this problem. It really ****'s me off. Heres a vid of it. It only does it over 21psi. It makes a flutter sound under full boost from the air filter.

some people said it could be from my ball spring MBC I know most of you have more experiance so thats why im asking

 

what are the specs on the turbo? if youre pushing it out of its efficiency range...you might be hearing the "pigeons" aka compressor surge.

 

t3/t4 57 trim .63 a/r stage 3 wheel. garret turbo.

 

I'd say it's your MBC, your wastegate spring is too small (only 2x the boost should be used), or improper vaccum source (to many things connected to a single vaccum source)

I have a 1 bar spring in the tial 38mm already. I dont have anything T'ed. I barely have any vacuum lines. 1 is T'ed off to the MBC, all the other run from the intake mani. in separate lines. I bought a 7psi spring from here so im going to add to my 1 bar spring should put me close to 22psi. Hopefully that fixe's it
