[TR] TR3's, electric fans and fan shrouds

[Bob Danielson]

Frank........... if you go to the Spal web site http://www.spalusa.com 
you'll find that they carry a line of low profile fans. When you navigate to 
a specific fan, you'll find a link to a pdf file with all the fans 
dimensions & specs. There's a couple of 14" ones that are a tad over 2" 
thick.  Their medium profile fans look to be in the 2.5" range.

here in California's desert i suffer over heating during stop and go traffic 
in
the summer. driving has always been fine.
i have been running an old, unknown CFM, 10" electric fan.
i bought a nice big 14" spal 1720cfm electric fan. made a great mounting 
bracket
on the old beat up radiator. but, whoops the fan is too fat in the middle 
(like
me) and interferes with the tube that bolts across the strut towers. 3 3/8" 
fan
height Vs 3" tube to radiator distance. DOH!
so lots of questions:
has any one found a high volume 13" fan that fits?
has anyone ever fabricated a shroud for their fan?
seems to me that shrouding off 50% of the radiator kinda kills the idea. i 
know
all of the fan area's air is forced thought the fan hole in the shroud at
driving speed, but there is probably an empirical balance point between free
area and shrouded area.
any one played with this?
thanks
Frank
