read what #rotor said, it's easier to put the inlet/outlet at a 45deg angle. see my drawing B a little further down the thread. when i checked, #rotor's image didnt work, but his site does up and down like that, so eventually it'll be back up. i am trying that aproach soon. to make sure everything else is kept constant, i am using one bottom and making two diff tops.
