Hey guys, I installed my bov that I just bought from a forum member. I can't hear a thing, no difference at all. Am I just an an idiot or is there no notorius "swoosh" sound unless i upgrade to hardpipes and a cai?
i cant really tell from the pics but do you have a seperate line for the BOV and the wastegate? you definately want to run 2 quality lines one from the brake booster line T from close to the IM(this is generally the strongest boost/vac source just put your T in the line close to the IM as there is a one way valve in the Line to the brake booster that you want to be on the IM side of ), one from the stock IM nipple but regardless I never really got alot of noise with the stock plastic pipe and intercooler. also after tightening it on the stock piece and taking it on/off many time the stock pipe becomes damaged over time and may crimple/warp where you mount it.
If you want good driveability and good sound with the stock Intercooler you may want to look into getting a set of hard pipes made and relocate the MAF to the cold side. Place the BOV on the hot pipe or the cold pipe before the MAF. There are a few aftermarket pipes or you can always spend around $100 buying piping and couplers off ebay. If you have a local source for silicone couplings and T bolt clamps you could also have a local muffler shop weld up a set for you. Just pull the stock pipes off in the parking lot and have the shop duplicate them for you.
