Thanks! That's exactly what I will do then. 4" exhaust flew & a 3" intake. The pipe that connects my firebox on the bottom, goes up 13" to reach the cooking chamber.......what diameter would you say that should be?
Were it me, I'd go for 6~7cubic inches for the intake and 12~14 cubic inches for the exhaust flew.
the area of a 2" dia, circle is ~3.1cu. inches
the area of a 3" dia. cirlce is ~7cu. inches
the area of a 4" dia. circle is ~12.5 cu. inches
