[TR] Electric Fan Location

[A Daniel Cronin]

Listers:
Am rebuilding a 55 TR2 and will be installing a Flex a Lite 1050 cfm,
9 amp load, 10 blade, 12" diam. electric fan with variable speed control kit
and manual on/off switch on an aluminum radiator without crank hole.  Radiator
effective area is 11 1/2" wide x 18" high x 2 1/2" deep.  Stock Tr2-3b
radiators were about 17" x12" x3" and the crank hole was up from the bottom of
the fins about 6 1/2" and the stock fan appears to span the entire width of
the stock radiator, some 13" diameter, so it is pulling air into the bottom
2/3's of the radiator.  The grill opening on the 2 starts just under the crank
hole and has an opening at the radiator face of about 11" high and averages
13" in width.  It appears as if the fan is pulling half its air from under the
front apron lower skirt (the 6 1/2" below the crank hole) and the other half
from the lower portion of the grill opening.  It then seems that the "ram"
effect of air being forced thru the upper 70%
 of the radiator when under way completes the cooling tasks.

Given that the
fan I will be using is slim enough to be positioned at any height behind the
radiator (puller) without interference from the cross brace connecting the
spring towers, where would you think would be the most desirable location to
install the fan.
