Where Is The Best Place to Recurriculate BOV To?

[rico05]

Is it really into the intake tract just behind the MAF before the turbo? Wouldn't it be better to have it go back in right before the TB? I HAVE to recurric my BOV b/c it is killing it at idle it is so rich, and makes driving on the street very tricky indeed. I am building custom piping, so I just wanted opnions

There really is no difference where you have it recirculate, provided it is after the MAF (kind of obvious).

Is your BOV on your hotpipe or coldpipe? I would just go to wherever is closer

Well if you route it back to the to before the throttle body, then you wouldn't need a BLOV do you? The main purpose of the BLOV is to release the pressure inside the hotpipe, intercooler, and all piping before the thorttle body so that it does not return to the turbo to stop it instantly (turbo surge). If you route it back to before the throttle body, the pressure goes right back into the same place it just came from, so in turn, the only other place it can go is back to the turbo. The reason why it's route back to after the mafs and before the turbo is because the pressurized air from the blov goes into an area where air is always drawn in or always 0 to negative vac, never positive. Not sure if you understand but DO NOT ROUTE IT BACK to before the throttle body, if you do so, you'll have a whole new meaning to busted turbo.

my BOV is mounted about a foot away from my throttle body (coldpipe?), and I've been having stalling/backfiring/rich fuel issues as well. so should i recirrculate to a spot between the maf and turbo?

btw i have a fmic & hks ssq bov, but the setup was done by the shop at the time of motor swap.

yep, if you are gonna recirrculate, it has to be after the mafs and before the turbo.
