[FC] 8 vs 12 Plate Oil Cooler Question!!

[James Davis]

 From Bob Helt's book "change from 8 plate to 12 plate cooler -18 
degrees in oil temp on a 100 degree at 80 mph".   Side shields on the 12 
plate -7 degrees under the same conditions.   If you are worried about 
oil temperature, two folded fins or 8 plates will fit in the stock 
location if the top cover and lower air door surround is modified to 
fit.   There is a tech tip to that effect published in the mid 90's if 
my memory is ....

> More oil cooling in a Corvair is generally a good idea.  I'd upgrade any FC to either a 12 plate or a folded fin.  I've heard they are similar in how much they cool the oil, although I haven't seen a direct temp comparison that I can recall.  Since you have the 12 plate, that's what I'd use.  Make sure you also have the lower shroud for it.

I just rebuilt my 110 64 motor wtith 145 cubic in crank and 40 over pistons with early model cyclinders and 260 cam ,and  i have my 8 plate with side shields ready to install in my rampside, was wondering would it be that much of a difference switching over too a 12 plate oil cooler!
