Re: Vent BOV to atmosphere w/ MAF driven ems
 

I'm venting to atmosphere on the WRX with a turbo xs blow off valve, the type that the whole shaft moves up and down and opens some wholes on the side, because it stays shut until I shift I have no problems. It does backfires sometimes under hard acceleration when I shift.

I tried using the factory subaru bov, venting to atmosphere and it ran like crap. The greddy type-s can be adjusted to stay shut so it works too.
The one on the picture postd up seems to work good, it does both things.

Where is a Bullshit Flag when you need one :P

I did this on my old MX6 GT... car accelerated so much better, and boost came in way sooner, only issue was drivability and backfiring ::) ... it sounded cool for the 30 minutes I left it like that...

Switch to MAP, it'll be happier...

What about mounting the BOV before the MAF meter?

Even with the valve fully closed at idle I'm still get a low input maf code, so recirculating the valve isnt going to do ---- :-\

Blowing through the maf isnt a option

Jeff just wondering what you ended up doing eventually about the BOV? I have a '90 Saab 9000T and am going through the same ----
