Jerry, You are correct in thinking the Ellison does not like turbulent air. The absolute best thing for you to do is study this web link http://home.hiwaay.net/~langford/corvair/airbox/ which happens to be Mark Langford's air box design and as best as possible duplicate it for your engine. I used his design for the most part and neither he nor I have had any problems with our Ellison carbs.

Netheads, Here are some of my thoughts on our carbureation problems..........whattaUthink...??? Every carb that I know of except the Ellison intorduces fuel into the airflow thru one orfice (hole, jet). Only the velocity of air passing that hole has any effects; the direction has no effect. Therefore whether the air is parallel to the throat of the carb, sometimes called 'ram' air or circular' called 'turbulant' air, matters not; only the velocity..... Now the Ellison has a series of holes in a spray bar across the throat of the carb with fuel comming out of each and sensitive to the direction of the airflow. As a matter of fact, you get your mixture control by changing the angle of these holes to the direction of the airflow. So it seems to me that the Ellison would not tolerate turbulent, non liner, airflow very well. Therefore I do not think that our 'plenum' intake is going to be very satisfactory and we will probably have to go to a more linear, 'ram' if you will', intake. We will not be looking for any 'air packing' or '.....charging' effect, just liner down the throat airflow. Comments and or suggestions will be most appreciated. Maybe I should jump into a foxhole.....???
