Re:Lowest boost for BOV
Fixed the problem, the holes in the vaccum tee was too small, so I bored them out.
Only opens after 5psi. Now keep in mind that this is only when I rev up in neutral. I can rev up to 5psi in neutral. It opens a little at 3 and 4 psi but it doesn't open up enough and I can still here compressor surge.
Is this normal or all BOV's like that?

Re:Lowest boost for BOV
I find this whole "getting 5psi in neutral" deal much more odd than the compressor surge... Who can build boost in neutral? What car / turbo? I knew/heard that some VW's running that tiny kkk03 deal could, but my t3 doesn't build a pound in neutral and I'd be hardpressed (but i can) to get my BOV to sound in neutral.

Re:Lowest boost for BOV
b16 is confusing himself and everyone else.
BOVs are open with vacuum. they close at WOT <--- NO VACUUM
i hooked my BOV up to my car when it was NA and reved it a couple times and the bov opens and closes.
maybe that bov is made for a race car or something? i have no clue

Re:Lowest boost for BOV
Sorry for the confusion guys. I fixed the problem; the ports in my vaccum T were too small. I opened them up and now I can enjoy the loud crack of the wipe sound of the BLITZ SUPER SOUND BOV!!!! MUUUUHAAAAHAAHAA!!!!
Still get a little compressor surge under 3psi but I think that is normal.

Re:Lowest boost for BOV
how can you be using a 1/4" line and still attach the vacuum line to the bov?
why i ask is because im having the same problem, i get flutter, or compressor surge at all psi with my hks ssqv, and im running 10-12psi. so maybe the vacuum line is just too small?

Re:Lowest boost for BOV
Yes, the vaccum line is too small. I have upgraded to 3/8" fuel line for the vaccum line to the BOV. I know that the 3/8's is bigger than the nipple on the BOV but 3/8" ensures good air flow to the BOV.
This is another "less restriction the better" situation. I put hose clamps on everything and have noooooooo problems.

Re:Lowest boost for BOV
Oh yeah, make sure the holes in the vaccum T are close to or the same diameter as the 3/8" hose. And no you don't have to use fuel line (expensive); I just used it because everything is very close under the hood and I didn't want something like fish-tank line to melt.
