Finally got it to work properly. For ports A and B, take the line off the stock bypass valve and tee it so u can supply both ports, this most people knew already. However when choosing the boost only line, some members said to use the intercooler line by the tmap sensor. This set up caused it to "flutter dump". When i changed my boost only line to the waste gate actuator line coming off the boost solenoid just below the intake elbow, i got the perfect whoosh. One thing i wanna take note on though, is with the flutter dump set up, the engine didn't "bog" for a second after blow off, my guess is the air relieved slower over a longer period of time, therefore having a smaller effect on air/fuel. However with my current setup, it will bog a second after shifting, but its only noticable if your not on the gas. When i got on the gas pretty good, i didn't notice it. Anyways, problem solved. I just gotta get the intake modified to handle recirc and the bogging issue should go away

 

So you are having these problems cause you wouldnt get a block off plate?

 

nope, i have hahns block off plate installed

My main problem was the source for the boost only line for port C

 

oh. i am still confused on how it works...i need pics :P

 

I think he is having those issues with the bogging because he is venting to atmosphere instead of recirculating the air. Those other boost related issues were because of the lines being hooked up incorrectly.

 

i thought we could vent atmosphere with no problem? i guess ill have to get this professionally done so they can recuirculate

 

Technically you can safely vent to atmosphere. It just creates a temporary rich condition right after the BOV vents because that air mass that the MAF measured is not the same as what the engine receives because of the blown off air. It is perfactly safe for the motor but will cause poor part throttle acceleration between shifts and possibly a poor idle.

 

ahh ok...

so basicly we need to recuirculate!

how is this done?

 

You have to buy a recircualtion kit like the ones Dejon sells to go along with your BOV. As for specifics on installing the recirc kit I an not quite sure were the recirc line goes. You would have to ask Dave a Dejon or Bill Hahn they would both know how to install it.

 

I purchased 1 and 1/4 inch vinyl hose to connect to the recirc fitting of my bov and i also purchased a 1 and 1/4 inch 90 degree plumbing elbow to which im going to jb weld into my stock intake downstream of my MAF sensor.

Mazdaboi: When i have my stuff all said and done, i will try to get some pictures. The boost solenoid can be seen if u jack the car up and look at the intake elbow junction into the turbo.

 

ahh ok...yea Pic's would be lovely!!

cause i dont understand how to do this...

 

maby a how to.

 

you didn't fix the issue.
sorry man it is a good try though.
mine is working exactly like yours is and the problem is still there its not so noticibale but it is still there.

Trust me I tried everything but recirculating before giving up.
the problem lies with the factory bov control solenoid.
it gives it vacuum for too long.
nothing you can do with the way you run the vacuum lines is going to change that.
we need to be able to tune the ecu to decrease the time it opens the solenoid that is the only way to fix the issue.



But please if recirculating fixes the issue let us know

I already purchased my intake from dejon with the recirculating pipe so when it gets here I will try it out.

 

I wish I had the option of purchasing the top mounted bov flange

 

Redcomet, what are u saying the problem is? The bov is opening for too long????

factory bov control solenoid? are u talking about the solenoid to the left of the intake manifold or the boost solenoid underneath the intake elbow? If its the latter of the two than thats boost your getting from that signal. I went as far as removing all the lines to the bov and running my line back to the bypass valve. when i hit high boost, the bov would also lift with the bypass valve. So to me it seems even without any lines going into the bov it operates properly (to an extent).
