ok get this haha
while driving my car i have this very strange issue
in boost and ONLY in boost at ONLY 20psi my turbo (not sure if its the turbo)
makes a very very strange clicking sound for about 3-5 seconds
then stops
it sounds like an aluminum chatter its VERY quick and perfectly spaced apart sounds like a machine gun or something like that and i CANT figure out what it is i may need some advanced guys help on this one

 

Looks like you need a new turbo, your in luck cause I am selling mine. 400 shipped to your door.

 

And I'll take your broken one
I never heard a turbo have a clicking sound unless the compressor wheel was hitting the compressor housing. This would happen if the shaft was bending while under boost, but I don't think that's the problem here. It could also happen if for some reason the bolt came loose that holds on the compressor wheel. Lastly, something was sucked up into the turbo. If this was the case, you would here it all the time.

 

What kind of boost controller do you have? Asking because mine makes noises like you are explaining, just not at the same time.

 

yeah its ONLY at 20psi EVERYTIME EVERY gear in 1st it doesnt last as long 2nd you can hear it for 2 seconds 3rd its like 5 seconds 4th its awhile
i dont know what it could be its so strange
but as i build more boost
it goes away
it does it at 20psi untill it creeps up to 22psi then it sits at 22psi untill redline

 

its a hallman boost controller

 

Definately check your boost controller. Don't want to jump to conclusions. Did this happen right after you installed your boost controller?

 

nope ive had the boost controller for a long time

 

I would say it could be the mbc. At max boost you will have the ball lifting and seating at some frequency which I guess could make enough noise to hear. I cannot hear mine (car too loud) and from the logs I think it happens much slower than what you are hearing. If you have the hallman with the lightweight ball it should cycle faster.

 

Then I'm out of ideas. Manual right?

 

 

Bump... I'd like to know whats causing this
