Gene;

Go far the twin fan set-up. I ran the single fan,in fact the same identical one in your picture and had terrible luck with it.. I custom made two different shrouds and it did not do the job.....I'm presently using a single fan off a Caddy or Olds I go at a local body shop and I can idle in 100 degree heat for 45 to 60 minutes at 180 to 190 degrees..........

The dual fan set-up has far better shrouding than you can build and will work better IMHO.........

Actually in the course of two years I tried four different electric fans and more different shrouds till stumbling onto the Caddy fan....It is 17" with curved blades and does not pull as much amperage as I thought,very happy with the results......
