Thread: bov ???

do i need to recirculate my bov if im going to run nistune type4 board on my b14

recirculation has nothing to do with your ECU, it has to do with your MAF. If you run blow through with the BOV before the MAF, you don't need to recirculate, otherwise, you should.

im still confused

I think he's basically saying you're asking the wrong question.

The question you should be asking or the answer you should tell us is where you will place your MAF and BOV in relation to each other..

-G

Blow through is where the maf is placed in the pressure side (cold) of intercooler piping after the turbo.

Draw through is where you place the maf before the turbo

got cha thanks

on the charge pipe that goes on the intake so what goes first bov or maf im doing pipes this week sorry for all the questions

If your maf is on the intake pipe, (before the turbo) then the bov has to go after it and be recirculated.

you should really get a handle on how this works before you design your piping

Well I'm still confused but what I should of asked is were exactly do I have to put it so I don't have to resirculate does anyone have a pic
