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?
