Come on Tracy, someone will think you are a politician with that answer. ;-) I said "right flowing". How did you bend the air to your will? Are you going racin'? and trying to keep the secrets to yourself?

Who said "right"?  I said "enough".  And that is a subject for a book, not an email.  But as someone previously said, all the pieces have to be appropriate, inlet, duct, diffuser, Heat exchanger, outlet.  There is no mysterious right flowing air, you gotta coax it into cooperation at every turn.

Tracy,

You said: Now that I have enough air flowing through it, my 11 x 11 x 2 cooler is doing a nice job at 300 HP.

Could you share the details of how you got the air to flowing "right" with minimal drag?   What steps did you take to find the mysterious
"right flowing air".
