Sorry i dont own a wrx, but i tried.

My s/c kit came with a bosch bypass valve and ive read so many bad things about it since its plastic and its a diaphragm type.

I dont want a atmospheric bov but i want full recirculate bpv. I just want to hear some suggestion on what to use ?

peak boost is around redline 7.6psi @ 6300rpm

thanks i-club =)

 

ive searched by the way, but there are too many post in regards to people wanting atmospheric BOV and the Psssshhhh sound then the flaming came.

im not into the "pssshhh" sound, i just want to improve the design

 

You didn't state what type of car you drive (and I can't read that l33t-speak in your Profile), but I would use whatever the supercharger kit came with. Avoid mixing and matching parts until you've installed the kit and driven the car. Is this bypass valve 100% atmospheric now? If it turns out you don't like it, ask the manufacturer for options. If this is a quality kit, the thing is made to work as a package.

i drive a 06 scion tC

i have the TRD supercharger on it and its supplied with a bosch bpv (model#102 / identical to audi/vw)


Like that*

the bypass valve is recirculated.

 

I read good feedback and post about GFB, i just ordered a universal hybrid from GFB.
