Hello,


Well, I have been looking for an alternative to doing a BOV. I found this Bosch Bypass sport value. I was wondering what everyone else thinkings about repleacing our 108 bypass value for one of these sport 110 values....

here is link... http://www.hoppenmotorsport.com/bypass.htm


Also, I wasnt the one, who discovered this it was o5fmtc. thanks man.

 

yea, its a good bpv...its been known about for a couple years now on this site...id say majority of people upgraded to this as their first s/c mod...it holds boost a lot better than our stock 108

 

Will this just hold better boots or does it give you the BOV sound.

 

Just holds up better, even my Turbo XS BPV is bearly audible.

 

a BPV does give off a slight sound...but nothing ur gonna hear over the engine while running. If you want the BOV sound...go for it. custom fit a BOV on the intake tubing...has the same action as the BPV i believe...could be wrong though, i'm still very new to s/c. Mine sounds great though and it's the HKS SSQV BOV

 

Well after thinking about it..maybe going for the BOV sound isnt the smartest thing do. I want to voild anything on my car...but BPV looks like stock. So I'm assume if something happen toyota wouldnt notice it.

but my question is your stock pulley put 7.5 PSI and motor only get 5psi. Where does the 2.5Psi go and how can get that back in motor?

 

getting a BOV will not void anything unless it causes the intake tubing to crack or split or some other freak accident...could also be caused by a BPV though so it's really just the same

 

no problem bro.

 

Thanks for the link, I'll be going S/C soon and I think this will be my first mod.

 

me too....

 

Though, I had a Boost gauge when the stock BPV was on, and it read a full 7psi, even 9.5 when I had my NST pulley. Maybe it's just the luck of the draw.

 

Not true, the TRD warranty for the S/C specifically states that if you change the intake, exhaust header, pulley, or bypass valve you will void the warranty for the S/C.

Normally yes what you said is true UNLESS otherwise stated.. I recommend the 110 BPV because it looks exactly the same and the PN only varies slightly... to the untrained eye, it will look like stock and most toyota techs wont know the difference.

However I myself have been looking at getting a 50% bypass 50% blow off valve because doing a full atmospheric blow-off will freak out the car, because our cars are MAF based. If we had MAP it wouldn't much matter

 

Thanks for everyone help....I just bought my 110
