Wouldn't it be easier to machine some off of the venturi? I mean, you've got a FAN in front of it so machining a little flat for clearance isn't going to hurt breathing efficiency much, if at all.
I thought about that breifly. I was going to need to file away almost half of it. More than I was willing too. I'd rather turn down the fan at that point, but I am going to need some kind of an adapter anyway, So i think this is the path of least resistance.
Thanks!
