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)

Mike, use a Bosch bypass valve (late 930 style) - cheap and will handle the air folw on your T-IV just fine. If you want better go Tial...uses the Bosch principal but made from billet. The "Free-spool up" is what you get with this...and you'll still get some good blow off noise. If your using CIS on your design, stay away from a BOV--it basically gives you a big vacuum leak on decel, and a bigger problem to drive around (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)
Good to meet you at the Classic !

likewise meeting you....too bad you didn't toss me the keys to your car, but I forgive you for that, (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

I have an aftermarket programmable fuel injection, so no worries there about the CIS issues....
