I got the Greddy rs type BOV today and hooked it up . I have cams and only get -6.5 in of vacuum at idle . The BOV wasnt opening up at idle . I adjusted it all the way out and it still wouldnt open up at idle . The instruction are all in Japan . SO no reading it .Does any one know how much vacuum is needed to open it ?
Thanks Bill

 

well I found out that the Vortech has a Bypass valve and not a BOV . So if you have a SC . Only a Bypass valve will work . Learning lessons every day with this car .
