I would also be interested in a somewhat guess for Terry's ram-air hood for the
older daks (I know some DML'ers have these). I currently run a 14x3 setup and like
the ram-air hood but I am also looking at a quick-d intake. From the chart I would
have to go with a 8" cone. If there is not very much difference in the 14x3
ram-air hood and the quick-d intake then i'm going with the quick-d only because
it's cheaper. Either setup would go well with the stage I tb but I just want the
best possible setup for the money. I think that some of the other genII owners
would probably be interested to right?
