Bypass Valve to Blow Off Valve |
|
| This modification will vent
the blow off which occurs during shifting to the atmosphere creating a
whoosh sound. After some experimentation I have found that this design
gives the best sound. This modification is only for Saab's without Air Mass Meters (T5: 1994-1999). I have heard arguments against BOV, but I think the benefits out weight them. I've measured the intake temps as high as 140 degrees F, and I do not want to recirculate that air. Parts - 10" Hot Water Pipe, 1" Diameter 1" Adapter to 1.5" (pictured white) Hinged Check Valve Circle Clamps Rubber Stopper Cost: <$20 Time: 30 min Difficulty: Easy |
