This would be nice since they are a quarter the price of a tial. How do they really hold up?

In a sticky from this site, i've read that they are a good choice, but i'm more curous now.

 

if you want a OEM cheap blow off valve Nothing wrong with a Crushed DSM 1st Gen BOV

 

Well, you know, this unit is just over $40 new. Incredible price.

Hey, uhhhhhhh, what's a crushed dsm bov? Obviously a part from a dsm, but it isn't really crushed is it? lol, I really don't know.

 

ya they actually do crush them. had several friends running them on there budget builds and held fine. One buddy was pushing 22psi and did not have any boost leaks. You can pick them up for $20-30 if that and they work great. only part i would use from a DSM

 

The Porsche valves are known to fail, use a DSM one instead.

 

30 bucks for a ebay greddy type rs knock off. work very well from my experience with two of them. held 16-18 psi just fine and flow well enough for that amoutn of boost once getting toward 20 psi they started to flutter. if your trying to get away cheap though there great
