Chris and Alana Posted January 5, 2007 Share Posted January 5, 2007 What size restrictor ring restricts boost to 1.0bar and what size for 1.2bar? I only want to boost 1.0bar and have ordered a 2" rr, is this right? Quote Link to comment Share on other sites More sharing options...
supRo Posted January 5, 2007 Share Posted January 5, 2007 It will vary from car to car. Start off with one and see if it holds the desired boost - If not then you'll have to get one with bigger/smaller hole. E.g on my car a supposedly 1.2 bar ring was making 1.4 bar Chris Wilson sells them - Speak to him Quote Link to comment Share on other sites More sharing options...
