blow off valve venting to atmosphere or a bypass valve???
with my car being as "rice" as it is, a loud BOV almost seems like a natural (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |

If you're using any kind of airflow measuring device with your FI, you have to use a bypass valve. Otherwise you're losing metered air and you'll run rich every time it activates. If you aren't measuring intake air it's just a matter of preference. More plumbing vs. more noise. Our WRX had a blowoff valve on it when we got it (and it has a mass air flow sensor.. so it would run funny after it vented) It was kinda cute at first to be going around making PFFFT-SHWEEEE! sounds all the time, but it got old real quick. Fortunatley it came with the stock bypass valve too. I put the BOV on ebay and got $200. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
