BOV installation process and recommendations
BOV installation process and recommendations
I was racing a new mustang GT earlier and pulled on him, but shifting from 3-4 I hit a huge amount of back pressure and I know from some old projects I've done, that a BOV should resolve this problem, but I've heard around town that it's a pain in the ass to install one on the new T/C's. Anyone have any recommendations on a good BOV (I don't give a crap what it sounds like, I just need the performance)? Also, I could use some ideas on exactly how to put one on...by that I mean what all parts are needed? I'm sure that it's not a direct bolt up and drive process. If anyone can help me out with this it'd be greatly appreciated.
It's not hard to install one at all. You would just need hard intercooler piping and your bov and flange or whatever. You'll also need a block off plate if you want to vent it to atmosphere. The block off plate gets rid of the stock bypass valve. You can always recirculate it if you want. Not exactly sure how to do this, though. Someone please correct me if I'm wrong.
^this. If you vent to atmosphere without moving the MAF (which would be a pain) then your car would bog between shifts and make your acceleration time slower.
i have a bov and MAF in same location. no bogging. no longer spool time. no lack of acceleration. no CEL. no rich condition. No anything. Have Dejon upper charge pipes, greddy BOV flange and Greddy RS BOV. I even have a recirc tube for it but I dont run it b/c it makes absolutely no difference in performance. I thought we established within weeks of the SS/TC releasing that the computer adjusts so fast that a BOV is fine....

Basically the atmospheric release of pressure makes the car think it has a big boost leak... hence it'll go really rich for a few seconds... sometimes to the point of throwing a code.
I have gotten my buddies figgured out finally no more "5psi limp modes"
I'm still on the stock BPV with dejon spring... making gobs of power without any issues whatsoever!
I have an HKS SSQ bov vented to atmosphere along with Dejon intercooler piping. I'm untuned. I'm not running too rich or too lean and I'm not losing any boost. Everything feels fine to me. Never got a check engine light or anything. I even had my friend with a computer check it out to see if it was throwing any codes or anything everything was perfectly fine.
Kevin your MAF is on the intake... your BOV is on the hotside pipe... they are not in the same location.

Is this the problem you said it's having?

(Just giving you a hard time, man.

Had this guy i know put a bov on my car stock.
He made a steel pipe to fit cold side of ic.
its steel after the sensor w/ the flange welded onto that.
The car runs fine then goes into limp 3psi.
the more i romp on it the quicker it goes into limp mode.
and if i drive around like a grandma it never happens.
and if it goes into limp mode i have shut the car off and it resets the ecu so i start it back up and it will run 15psi again till it re-occurs
But its a cheap 50.00 xs power type h
which is the turboxs type h replica.
Every one i know tells me its the bov. i have a buddy w/ a turbocharged civic w/ the same bov and it does the same thing,
just wonderin your opinions on my situation.

uhhhhhhhhhhhh
Our cars come with a built in bpv in the turbo housing. You guys are trying to add a bov and arent tuning the bov or car properly!!!! Why do you need a bov with a stock turbo? There is zero reason! Are you getting boost leak? over boost? On top of that the car is setup for recirc and you guys are switching it to vent to the atmosphere and have zero idea what you are doing. just because its a turbo doesnt mean you can pnp a bov on the car. Even the guys putting the dejon spring in can have massive issues...

so he data logs and knows his specs in all weather? He knows his boost pressure, afr's, iat's, exhaust temps, running rich or lean? probably not.... just because you dont throw a cel doesnt mean its not a problem. The SS/TC's ecu is very good at changing to compensate for things like that. Is he tuned?
