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.

im sorry that i bring up a old topic.

but i wanted to know the same, how does the stock blow off valve sounds when venting to atmosphere?

i know that you can unplug the BPV, and plug something in the airbox hole were the BPV should be...but how does it sound...?

I have both a rfl and stock abv and often swap them when I am bored. The stock bov sounds like a softer rfl. Sounds better IMO , its only audible when you get on it as opposed to the rfl that's loud all the time. Sometimes I think the rfl blows off in vacuum too lol.
