Venting the Stock BPV on an ST205 GT4, Bad or is it ok? Options

[Goonter]

Ive been reading all night about blow off valves and bypass valves. All i seem to read about is bad things (besides the sounds it makes) about blow off valves. Things like you run rich, lose power and crap like that. I wanted to know if this is the same way for 3SGTE ( i would assume so) Also does running rich every time you shift gear waste a noticeable amount of gas?

Also say i don't get a BOV. The BPV is designed to recirc the air back to the intake box. If i get an Apex'i intake filter to replace my box, Is there any way i can recirc the air back to the intake system? (btw I'm just getting the filter. The rubber intake piping will stay. I noticed the BPV is bolted onto the box so i see no way of getting it recirc'd to the intake system unless the piping was metal and a flange was welded onto it for the BPV to bolt onto.

I wish I had a definitive answer for you, but let me try to answer your question with a question. "If blow off valves were so bad, then why do thousands of people use them?"

With certain blow off valves you could likely route them to recirculate with your intake if this was a big concern. Or you could use your stock diverter and make a custom intake to mount it to. I believe Apexi makes a pipe with connections for your diverter. Another thing that you should look out for in your research is whether the car owner's that are complaining about them are using MAP or MAF sensors. I understand that on a MAF sensor that re-circulation is necessary due to the placement of MAF sensors.

In short I think you'll be fine running a BOV. Have fun with it they sound awesome!
