I'm fitting a hotwire v8 in my defender, and the original discovery inlet arrangement won't fit easily...... I'm probably going to move the Mac to behind the throttle cable.... what I'm interested in is ... is there a recognized maximum length between the Mac and inlet...... I've heard stories of other engines making more torque the longer the length, to a point, but I suspect in my case a few extra inches probably won't make any difference......
Still an interesting question though, for me anyway.....
