my friend and i are have a dicusion about where to place my BOV, i think that closer to the tb is better, he seems to think that closer to the turbo is better, where should i put it?

 

It's my understanding that the closer to the TB the better, and that's were I am putting mine soon

 

yes but why is it better?

 

I think it's because that's where all of the pressure is rushing at the time, and you want your BOV to relieve pressure as soon as possible after it's closed. Having it placed closer to the area where it is closed should do this. In fact, lot's of BOVs (TiAl comes to mind) have a vacuum line running to that area for that reason.

 

yeah i have a hks ssqv and it has the same line

 

The reason I am putting mine near the TB is because it makes more sense to me that since the air in the piping is moving in that direction, would you A) rather have the air continue in that direction and keep the airflow direction the same, or B) have it near the turbo where when you let off the gas all that air in you IC and piping is going to try and travel back asswards towards the turbo, causing the air to becaome super turbulent and trying to flow oopposite the direction it was originally traveling.



that is my understanding of it, seems kind of important to keep the air flowing smooth when your shifting at 7k rpm with 15psi of air flowing to make your next gear go smooth.

 

im having 2 bovs. one near the tb, and one near the turbo. just in case

 

That's how I see it.
