hey guys
should i put my blow off valve before or after I/C
any difference with it in either location
thanks

 

I've heard people say that mounting close to the throttle body is better. That's how I have mine set up. Some people get 2, 1 before the IC and 1 after.

 

yeah i think after the IC would be better, close to the throttle body.

 

the less CFM you have to repack before the TB the quicker you will be hauling **** again when you change gear. thats the theory behind the cloest to the TB theory. it also keeps back flowing air to a minimum.

 

Yes I agree. It is best to place the BOV as close as possible to the throttle body.

When you change gears, you let off the pedal (accelerator) for a moment, and at this point the butterfly closes causing a standing wave of air which should be relieved out of the BOV ASAP.

In this way (as another member said) you will limit the boost pressure lost in the remainder of the piping, especially needed when you accelerate again, and want to come on boost as soon as possible, (less lag).

Cheers.

 

Mount it right on the Greddy Elbow near the TB. Like everyone else has stated it will get you going again faster.

 

Wow, a thread where everybody agrees with each other.

 

amazing................

 

Maybe we can argue about the distance from the TB?

 

hahaha, im sure its coming soon.. I say 4-5 inches haha

 

...then here I go f*cking sh*t up!!! I think closest to the turbine.

 

What are you thinking damnit????

 

I disagree with everybody! (What can I say, I'm Evil)

Seriously, though, IMO an atmospheric-vented BOV should be placed closest to the throttle body, unless you are using the stock AFM, in which case you should recirculate the air with a TBV mounted close to the turbo to reduce the plumbing. However, I don't think it makes a whole lot of difference, just as long as you don't put the BOV in a high-velocity area like in the middle of a pipe.

 

I put my BOV in the downpipe

 

Um, that would be a high-velocity area, not to mention the other issues, LOL.

 

I tried it on the sunroof, but I couldn't hear it release

 

hahaha....Try next to the radio...
