hi guys to day i removed the box joiner that sits between the maf and the inlet of the turbo, it has the main air inlet pipe in and out, a small pipe that is connected to the bottem of the boost controller and another larger pipe that seems to be a vacume pipe and pushes on to a metal pipe.

as i have removed the box i had no where to connet the large pipe to and it would not run without the pipe connected. so i connected it further down the line.

i have a blitz bov so there is a bung where the recirc used to be, i plumbed the large pipe in to this hole, the car runs fine but......

1. when i change gear the wastegate is really really loud now.

2. through the induction kit you can hear a loud humming like the sound of the fans.

is what i have done ok or am in about to blow the car up.

Thanks David

 

can somebody help. please

Thanks David

 

I fitted a K&N induction kit with the new pipe in place of the box. The position of the large pipe shouldn't matter.

The wastegate noise will be louder as it isn't contained in a box, so is noticably louder.

From what you have said i can't see any problems, unless you don't like the sound of the wastegate?

I'm assuming the fan like noise is when on boost? I get this. This is the sound of the turbo sucking in the air.

cheers

 

its not the wastegate, its the turbo stalling when changing gear thats causing your noise. as said you hear it because the airbox is removed
