i am a novice in FI world (sort of). i am in need of a quiet blow off valve, around 15-20PSI planned. don't care if recirculating or atmosphere vented.
i would also prefer one without flashy appearance, something like the old Bosch BOVs used in Nissans.

 

tial's are pretty quiet

 

this looks good

are they any good?

 

they will work, you would need to have a hose barb welded to the charge pipe with a piece of silicone tubing to mount the bov... then you'd have to plumb the recirculation stuff

 

the BOV will be mated to the carbon fibre charge box.

 

im using the turbosmart raceport 50mm and you dont hear a thing. I like the stealthiness of it. all you hear is the spool up

 

charge box? without the blow off valve on an intercooler pipe it won't work

 

the charge box encloses the ITBs. i am designing the box to incorporate the air to water after cooler as one unit.

 

I have a Tial BOV and when I giddy-up it sounds like the car is sneezing when I shift. Not loud but definitely not stealth. Of course they may believe the car realy does have have hay fever as the whole thing is stealth.

 

you say you are a novice in FI, but you plan on putting together a system with ITBs, and a custom charge box with an aftercooler in it? ssems a bit complicated for a novice. I don't want to discourage you, but if you are truly a novice you should do alot of searching, followed by a simple first system to get your feet wet. just my .02

 

why would you want a quiet bov? thats like having a quiet partner during intercourse lol

 

I prefer a quiet BOV

 

I used to be able to hear the 2 srt4s that lived in my neighborhood anytime they left the house, even 10+ blocks away.

 

my neighbor has an srt4 with the mopar block off plate, i never, ever hear his blow off valve... its all in how you drive the car

 

probably all with stock turbos that spool at idle and cars slow as *****

 

I like my women like my coffee

































ground up and in the freezer..lol

 

i am being facetious, plus i really mean, i do not know who makes good stuff. the other things mentioned are all fabrication.
i have also made a custom ECU and the harness for it
