A: The Hybrid option gives you a 50/50 valve. 50% vents back into the atmosphere, while the other 50% gets recirculated back into the intake. You can remove the flange plate on the rear to make that happen.

A: 50/50 BOVs on Subarus usually cause some backfiring, but it should be minimal with this valve, and backfiring generally does not hurt anything.

A: A blowoff valve can be used on a stock turbocharger. This is a recirculating blowoff valve in original form and will be almost silent, but if you were to remove the atmospheric backing plate you will see a bit of noise when venting to atmosphere. If sound is the priority something like the Go Fast Bits or Turbosmart valve may be the better option.

A: This valve is going to be vehicle (flange) specific. If the front mount kit you bought has the same flange as one of the vehicles in the confirmed applications list, it should mount up no problem. If not, modification would be necessary. Thank you.

Q: Compatible with Process West TMIC and recirculating hose ? buckner8410 years ago
-
-
0 of
0 people found the
following answer helpful
A: You should not have any problems with clearance running the Cobb BPV with the Process West intercooler kit. The angle at which the valve comes off of the intercooler still provides sufficient clearance to the hood while the SSQV is much larger than the Cobb and is much more prone to clearance issues. The Cobb valve was designed to reuse the factory return hose.

Q: 2011 Legacy GT? 13FRacing11 years ago
-
-
0 of
0 people found the
following answer helpful
A: This will not work on any 2010+ Legacy GT models. The blow off valve on the 2010+ models actually sits on the intake tube on the bottom front part of the motor and uses a hose attachment instead of a flange. You will want to confirm the size of the hose but there is a possibility that the EVO 8/9/10 blow off valves would be compatible.
