jamal Posted November 23, 2005 Share Posted November 23, 2005 Full atmospheric blow-off valves are for ricers. Unless you're running some ridiculous level of boost and it's necessary. Link to comment Share on other sites More sharing options...

nkx Posted November 27, 2005 Share Posted November 27, 2005 i could be wrong because im not familiar with TT subarus (we dont have them in the states) but you might have to run 2 bovs, which is probably going to be expensive. does it have 2 TBs? and does the car use a MAF (or 2)? if so, youre probably just better off sticking with the oem recirc valves.

oddcomp Posted November 27, 2005 Share Posted November 27, 2005 heh bov's are not just for riced cars they do actually serve a purpose atomospheric one's are just louder and make people next to you say WTF??? what kind of intercooler do you plan on running? as far as a twin turbo needding 2 of them well.. usually a twin setup is two smaller turbo's that spool quicker than one single large one but most of the time <not always> and are almost just as efficient in the upper boost ranges as far as placement goes if your using say like a wrx type of intercooler it already has a factory spot for a blow off valve if your either going without a intercooler <not a good idea> or with a aftermarket or junkyard unit that you have to make up connections for then pretty much anywhere just before the throttle body in the intake pipe is fine and you run the vacum line that attaches to it to either a unused port or you add a "T" splitter to some spot on the intake manifold maf based cars like what you "should" have usually need a recirc style of blow off where you can pipe the vented air back into the intake system between the maf sensor and the turbo inlet otherwise between shifts you will most likely encounter a backfire/poping noise in the exhaust sometimes you can get away with a vent to atmosphere type depending on who makes it and how much you can adjust the opening point me personally i run a hks ssqv bov but then again i am also not running the stock ecu or a maf sensor but they supposedly work well on maf based injection setups after you mess around with the adjustment screw on them Link to comment Share on other sites More sharing options...
