Down Draft Out - Hayden In

[davidbrady]

Thanks Curt, I appreciate the info and the detailed report and pics. It'll be interesting to see how the Hayden performs in the Mojave on hot summer day while traveling at speed. Other's have implemented this approach but the results as reported are anecdotal; i.e., no controlled environment testing with simulated real world conditions, and folks tend to be very forgiving of their creations! I can see the advantages of fan availability and ease of replacement. As Chuck points out the air stream provided by the squirrel cage fan does result in a 'developed' flow impacting the radiator; however, anyone who's disassembled the squirrel cage has likely noticed that the air is directed over only a portion of the radiator surface, approximately half. My concern is whether the Hayden can perform at highway speed when faced with real world static pressures scenarios. It may do just fine. Beautiful craftsmanship! I hope it works well for you.
