Saab Blow off valves are "Bosch" blow off valves, the cheapest on the market, I think I got one from napa brand new for 27 dollars. They are plastic and work ok, I wouldnt go anything over 10psi on them.

dam that's cheap, but if it works then iz all good. you could probable pull it apart and stretch out the spring if you needed more tension and then glue it back together with jb weld. it'd be fucked up if you stretched the spring too much and needed less tension after you put it back together and glued it.

 

It doesnt use a spring, it uses a diaphram..

 

thanks abaz, anyone else got pics of it a pipe? so i can get some ideas on how to mount it on a aluminum steel pipe. Thanks

 

Then attach them with a piece of rubber

 

do you already have a saab bov? if you want the pshhhhh noise that one aint gonna do it, it'll get the job done though

 

Dude what are you talking about? Those sound just like DSM blow off valves

 

oh, i didn't know. i was just trying to find out if they where loud the dsm ones sound good i drove one once.

 

Stole a volvo Adjustable BOV from a junkyard and I love it !!!http://pg.photos.yahoo.com/ph/maximu...74.jpg&.src=ph

 

thanks abaz for the pics. I kind of like the HOOT sounds that the saab bov makes when the car is idling lol. You can really mess with people at a stop light and play a song for them.
