BOV's - 100% to the atmosphere?
sup guys just interested in your 2 cents on this topic. I've got a 2002 WRX and am looking towards buying a BOV. HKS has come out with a kit for my car with the SSQV that vents 100% to the atmosphere. Is it possible to vent that valve also back to my inlet tract? The WRX uses an AFM. I've read that many cars with Air Fuel Meters will run rich if it is all vented cause the EFI system will be confused and pump more gas into the engine. Is there an easy way to move the AFM? If not, and if you can't make an SSQV not run at 100% than why would they sell this product. I know the GFB BOV has either 100% venting or 50%, and i think turbosmart does as well. BUT I ENJOY THEM FUCKIN LOUD!
Any help on this subject would be greatly appreciated.

Its not the Air Fuel Meter that causes the problems with running a Blow Off Valve vs a Bypass Valve. Its having a Mass Air Sensor vs a Manifold Absolute Pressure. Mass Air's take into account all the air pulled into the airbox, so if you lose some after it, the computer wont know. With a MAP, it could care less how much volume of air is in the intake.. it only cares about the pressure and then uses that to calculate the total amount of air. Therefore it could care less about any that gets gained or lost between the air filter and the intake valve.
Vented BOVs are annoying... mine is REALLY bad now.

That is a Tial BOV. Looks like it's on a small pipe, right? Wrong. That is 2.5" pipe. My turbo spools slow as hell, but, my BOV still opens when I let off the throttle VERY often. Pretty much every time.
