Bob, et al,
The "two-pass" vs "three-pass" discussion has me somewhat confused. I did talk
to
the Griffin Radiator people, who make aluminum radiators for most cars
(including
Tiger), and their cut was a little more mundane.
First, on a cross flow radiator, the driving design criteria on "number of
passes"
depends upon which tank you flow in to, and which is your outlet.
On a Tiger, with the input and output being on opposite ends, you must either go
with 1 pass or three pass. Two pass would require the outlet to be on the same
side as the inlet.
Now I do realize that many have argued that the Tiger inlet cap ought to be on
the
same side as the outlet pipe. I suppose this includes the inlet pipe, but am
not
sure. In that case you must have three pass, to get the water out of the
radiator.
In the standard Tiger arrangement, you are limited to one pass (standard with
copper), or three pass to get the water out the other side.
This makes the assumption that you have the conventional single row aluminum
radiator. If you are using multiple rows, and choose to use the passes between
front and rear rows, then you've got to take that, as well as your outlet
position, into consideration. Griffin does NOT recommend running the coolant in
this manner, but I don't know their reasons.
