Ok, I have an intake on my 760, i get the turbo flutter when i let off the gas like usual, kind of to imitate a bov. well here is my issue, doesn't this sorta damage the turbo becaues the fins are spinning backwards due to letting off the gas (excess air not being used) , and that is whats causing the flutter. Don't get me wrong i love the sound, but i just want to know if this will decrease the life of my turbo? And or does the cbv valve take care of this problem by venting that excess air?

 

You are hearing the CBV.The CBVacts like a BOV, but recirculates back into the intake instead of venting to the atmosphere. It is a good thing, so dont worry about it.

 

Thanks man

 

No problem
