notchpsi said:Put it closest to the TB as you can. That way when the BOV releases youll still keep the air flowing smoothly as it releases next to the TB. When you get back on throttle the BOV will close and your intercooler piping will already be filled with cooled air. If you had it closer to the turbo, when the BOV releases and you get back on throttle, youll have a tiny bit of lag as the intercooler and piping have to refil up with air. It isnt noticeable with small ICs like the TurboCoupe top mounts, but when you get to the bigger front mounts like Powerstrokes and stuff, it helps ALOT.
It is also very effective when using it a bypass valve because the air going back into the intake has already been cooled by the intercooler.
By the way, if you don't wanna worry about loosing metered air...get SDS!
Only problem is that it is close to $1000, I chose to go with this route, I love it!
notchpsi said:Because a stock Ford 2.3 turbo uses a Vane Air Meter which is mounted in front of the turbo. When you use a BOV vented to atmosphere it releases measured air out of the intake, but the computer still thinks it is getting that air into the engine. So it is adding fuel for air that isn't there. It causes a temporarily rich condition when the BOV is vented. I used a BOV vented to the atmosphere for about a year on my 88 TurboCoupe with stock computer and stuff. It did run a little rich after venting the BOV but within a month or so, it started to run like stock even with the BOV there. THe computer picks up on the air/fuel patterns and adjusts for optimum driveability. Try it, I bet you it won't run as ****ty as everyone says. True...if you use it as a bypass valve, you will be able to have a nice LOOSE spring tension on the BOV, thus allowing more air to flowout of the valve. The only real drawback to the BOV is that the spring tension has to be as tight as possible, so the car will not stall from loosing TOO much air, this means not as much pressure can be released from the BOV as opposed to being adjusted real loose.

mightypoof said:So basically it just gets confused and has premature opening? How much does a good Bailey's BOV cost ballpark? THanks
notchpsi said:I wouldn't worry too much about the BOV acting funny at cruise conditions anyways....when you drive a 2.3 turbo, the throttle is always to the floor
