Bov
So it says you get both the "sound" of a BOV and the benefit of recirculation, but doesnt say how. What is it, under low boost it recircs and high boost it triggers the BOV??

A thing called state inspections.... personally I dont feel like putting my stock DP back on every year.
So would this resolve the problems others have had with an atmospheric BOV, or do you still need to make other changes?

hmm interesting.....so they sell one that would work with our turbo? Does it mount into the charge piping like a typical aftermarket BOV?
What if we got just a typical atmospheric BOV like an HKS SSQV, and recirc'd it.... do you lose all the BOV sound completely??
Youd recirc it like this right?
INSTRUCTIONS FOR CONNECTING HOSES TO AN AFTERMARKET BLOW OFF VALVE
1. Remove the hose going to the factory Compressor Bypass valve (locate the tan plastic cap on the turbo above the compressor inlet) See pic at top of this page.
2. Connect this hose to the new BOV.
3. Locate the rear hose connected to the black solenoid valve on the intake manifold left side. See pic below. Install a 3/16" plastic "T" and 3/16" fuel/vacuum hose.
4. Connect the other end of this new hose to the tan nipple on your factory compressor bypass valve.
Thats from Dejons site.

And the sound, I still think it would be louder than stock, but not as loud as it running atmospherically.
Okay, so that Splitter BOV is the only way to recirc and vent to the atmosphere without losing sound?
I think I got it lol.
Ive slowly been learning turbos since I got this car, but I havent bothered w/ BOVs before....clearly.

You could even run the splitter without a tune.

To recirculate you would need to attach a 1" hose from the bov to the intake.
Like my old setup
So how did this set up sound? Just like a louder BPV?
Also, Howd you like Dejon's CP?
@HB SS/TC Where exactly does that line go into from the BOV to the intake? I have the exact same set up as you except I'm not recirced. I have a Dejon sri as well as the charge piping with the black HKS.
[QUOTE=fshizl;4489992]cops in my city actually get on their backs and look for cats on the cars that are modified... i rather keep it catted than catless cause i dont want a fix it ticket to go to a ref station and have to change everything back to stock.. i rather just play it safe...
Mine has the appearance of being catted but it is not. Looks legal, no codes and no emissions checks here in Florida.
