Tomb Posted July 3, 2018 Share Posted July 3, 2018 (edited) Hi chaps. Went to leave work today and my 04 350z , hks supercharged ( older version of the two hks kits available ) .. now flutters after even a small rev (before it would be a nice whoosh from the diverter valve) . I've had the car supercharged for over a year now with no issues. Any idea on what's coildnbe causing it? ive check the vacuum lines to the d/v aswell as the rest of the intake but after that I'm At a loss.

andybp Posted July 3, 2018 Share Posted July 3, 2018 definitely sounds like the bov not opening so if vacuum line is good then possibly valve itself I had to replace one because it was stuck closed Quote Link to comment Share on other sites More sharing options...
Tomb Posted July 6, 2018 Author Share Posted July 6, 2018 Fixed. There was a small tear in the bypass valve diaphragm. Luckily the legend @judiciousjoe had a spare bypass valve in his draw and sent it to me free of charge :o That’s why I love the Z community great bunch of guys always willing to help out. Big thanks again Joe Tom Quote Link to comment Share on other sites More sharing options...

judiciousjoe Posted July 6, 2018 Share Posted July 6, 2018 Glad to be of assistance Tom. More useful in your engine bay than sat in my drawer! Quote Link to comment Share on other sites More sharing options...
