Hey guys ive searched on google on how to convert the recirculation valve on my stock audi 1.8t to an actual BOV and im dumb founded. i've pulled the vaccumm line off hoping to hear the "pshh" sound and all was a fail. so i installed it back asap! my question is, is there a cheap mod i can do to get the "psssh" sound or what would be the easiest blow off valve to put on our a4's with little to no extra modifications. i know this is my first post, but im really wanting to rep. audi around where i live because all i ever see and hear are those "typical hondas" haha but can someone please direct me to a good how-to thread? i already searched the DIY and came up empty handed.. thanks guys!
