New Toy and a ???? BOV I recieved my Tial 50MM BOV today from ATP and i have a few questions.
Here is a couple pics....
Now my question arose when i opened the box......it says spring pressure of 11 psi..... what exactly does that mean?? does that mean i can only run 11 psi of boost???? Thats one of the big concerns.... the 2nd is the flange type.... it says MS....... i ordered stainless steal..... and it said Blue but as you can see its red like i wanted......... and the flange looks like Stainless Steal to me...... Jer can ya helpme out.......?? Its to late now to call ATP....
Thanks Guys

Spring pressure of 11psi? Maybe you can get a spring rated for a higher pressure swapped for that one for no charge. I would hope it holds more than 11psi. Call up ATP and ask the WTF. I'm colorblind, but I can clearly see that is a blue dot and not a blue BOV.
As for the flange it looks stainless to me, MS is usually on the darker side and stainless is shiny, but I am no pro on metals.
I think they botched up the packaging, ATP sold you this? You would've thought that they would have checked everything to make sure it was right?
Man that sucks, more delays..

Hope the overnight you a new spring if you need one and a blue housing too

I could be totally wrong, but it is my understanding that the 11psi spring pressure is the pressure at which the bov will be activated. So yes you wont be able to run more than 11psi. I know that you can put in a higher rated spring, but I am not sure if all tial models can accomodate it. my .02

I believe that is the psi where the valve will begin to open without boost on top. That is exactly what you would use to protect a intercooler from pressure spikes when you chop the throttle. Just hook the port to intake manifold boost pressure and you could make as much boost as you want as long as the throttle is open.

I think i understand that....... so i should be fine..... one way ill know id if i dont make over 11 psi huh
So your saying its for spikes and to protect the IC.......... I run my line for the BOV straight from the back of the Intake....... Thanks

i have the same bov and i am only running 9psi so i cut a coil out of the spring. sound great. i used the break booster for my bov. just t'd into it. my flange wasnt stainless and i had it welded to stainless pipe. not sure if any of that info helps or not
Like stated above, if it holds a magnet it's mild. If not it's stainless. 
Both of mine came WITHOUT any rating on spring pressure, but I bet Kurt is right on the opening pressure w/o a top port connection.
Connect them to any source after the throttle and they will open with an increase in vacuum.
I had to cut 3 coils outta mine to get them to open at idle. They just vent to atmosphere at idle now, and any opening of the throttle slaps them shut. They hold 20 psi just fine with the "weak" springs, and open real fast on drop throttle.
I had to get them open at idle to fight compressor surge, big turbo, low flow, relatively high pressure at idle. You could hear and feel the air flow in one turbo and out the other(the inlet), back and forth. It was freaking the hell outta my MAF's
Mount it before your intercooler if you can. I had a single HKS on my old setup, and it was mounted AFTER the cooler. It was too small to keep the pressure spikes down, and i was fighting split cooler endtanks. I'd reweld and add material, but kept popping the welds. Made sure these were pre-cooler this time

All that mattered is if it was Steel or not........ you cant weld aluminum to Steel..... or at least i cant..... all my new piping is SS piping......
It is magnetic by the way so it is steel........
