I'm sure you have seen a 1g BOV hold 17psi, but it was more then likely leaking causing a nice boost leak, so in fact your turbo was working that much harder to get it up to 17. Just crush it. That trick has been around for ages, and works just fine. I run a crushed1G BOV on my car and I drive around all day at 15psi without leaks, and have tested it up to 20 without leaks. After you crush it, it doesn't hurt to give it a nice polish job because they shine up nice! Here's mine after being crushed and polished!

 

My 2g dsm bov was leaking.
I put on a ebay RFL today and my boost magically flew up to 16 psi before I let off. Who knows how far it would have went up lol.
I was running 11-12 psi with the 2g.
Had that turbo spinning hard rofl.

 

am i correct in assuming that to crush the bov you just take a rubber mallet and hit the top cap a few times untill it crushes down a bit on the spring or is there more to it.

 

ummmmmm ciggarette's

 

I'm running two 1G DSM BOV - planning to displace more air than I trust one to be able to deal with.

 

damn, that must be a lot of air. A single 1g bov will discharge enough for my T3/T04E .50 trim setup at 25psi.

 

Workable, yes. Ideal, no. When I say that please keep in mind that I'm splitting hairs here.

I'm probably not flowing any more air than a .50 T04E compressor is capable of on this engine, but half the reason I'm going this route is because I plan to in the future. Having a friend who owns a DSM shop, this perfectly good swill is just laying around - when I offered to purchase, one of them was chucked at my head. The other one came off the Hand of God car (GVR #366/2000, hallowed art thou among DSMs) and was placed reverently into my hand.

If you look at some of the purely functional BOVs, the TiAL is a good example, they do away with as much air as possible, as quickly as possible. Then you have BOVs with smaller valvings mean to make loud noises, which are referred to as riceboy mating calls (OMG RFL!!!!1).

DSM BOVs have OEM quality, which is completely absent in the aftermarket. They are also inexpensive. When one won't do it, run two.

 

Just because it's OEM does not mean it's crap. A magazine even did a test of a few different blow off valves (i forget the magazine sorry), and the 1g DSM bov did suprisingly well compared to the competition (yes even aftermarket).

 

it was turbo sometin magazine, i have it they compare aftermarket to stock ones. really if someone was going that high in psi i doubt theyed not just buy a new bov. still though its not bad idea to try that.
