Damn. I can't believe that it bled off that much boost and it did it quick. I'm not sure how your BOV is mounted, but is it possible that the oring wasn't seated and it's leaking at the clamp? I know my tial was pretty tricky to get it to stay in place.

My BOV is leaking past the piston inside not where it attaches to the charge pipe. The boost pressure is opening it up, it just has a 1" hose barb connecton. Here's a pic of it when I had it installed wrong. I think the spring is too weak now that I think about it. I can put my mouth on the vaccum port and suck on it and it will open. I dont think any human should be able to do that.

Cleaned out the PM box a little.

It makes sense like you said, since it was installed wrong it weakened the spring allowing it to open much easier. But I would think that they would be able to withstand alittle more than that though.
I picked up my tial BOV for 100 bucks from a buddy of mine. If you are looking for a new BOV, I'll see if he has any more.

Alright, I'll give him a call tomorrow. You will have to cut a hole and weld the flange, but I know that's not a problem for you

Verdad Gallardo I was losing boost up top as well. It peaked at almost 9psi and taper off to 6psi. My wastegates were referenced from the ports directly on the compressor housing. I referenced it from the intake manifold and it never tapered off again. From what I understand, as the engine turns faster and moves more and more air, a greater pressure loss occurs after the intercooler.

Try referencing it directly from the intake manifold or anywhere after the intercooler.

The BOV in that picture looks to be installed wrong ???
Also...if you suspect its leaking, just get rid of the damn thing and test again.

Yes it is installed wrong in that pic, I fixed it and I'm still having the same problem. A friend suggested capping it off also but is that safe on a stick car?

There were turbocharged cars for years, before BOV's were introduced. There are some turbos that can be very fragile....but most wil be perfectly fine. Especially if you are running such low boost pressures.

i wouldn't just cap it off. no matter how much boost you run it has to go somewhere and the easiest way is back through the turbo. which in turns stops the compressor wheel for a mila-second, reducing the life expectancy. it'll sound like a dodge diesel, the compressor surge.
oh i'd get a tial bov anyway, hands down the shizznit

Having driven and owned plenty of turbocharged cars over the years...some with, some without BOV's....it will do no harm.
And it will allow you to eliminate the BOV from the list of possible problems.
