Reply to "48 IDF Webers, has anyone completed a running driving setup?"

DWR46, here's the issue and partly why I asked the question. 48IDF's have a maximum choke size of 40mm. The outside dia is 45.85mm, let's call it 46mm. So the wall is 3mm thick. You could machine the chokes 2mm to 42mm leaving a wall thickness of 2mm. But then it's not going to have much of a venturi effect. Now may be the booster venturi on the IDF is better flowing than an IDA so you have a bit better flow there. But it all seems a bit smallish!! Hence my original questions. There are a few manifolds made or have been made for IDF's, so that makes me think may be they work. But like I keep saying show me the evidence! Cheers
