So.. my 1916 (twin 44s, 044 heads, engle 120 cam) with std oild cooler and additional remote oil cooler has no flaps/valves installed.
Q. Do I need it? Will the oil over cool keeping in mind that I also have a remote oil cooler too?
I have the flap system from my original engine that I can fit so I can If you'all think its necessary

I think the answer is "if you have it AND it works - fit it"
I have never had a set.
None of my motors have cooked.
Question here -
If the flaps are closed
Where does the air go??
ALL through the oil cooler??
Wouldnt that cool the oil more??

Thanks blue 74! (nice name)
As to your questions not sure.
reading off Vw-resource it says ...
"The thermostat and vanes together make for a rapid warm-up (lower engine wear); and the vanes also help guide the cooling air where it is needed most - more to the hotter heads, less to the cooler running cylinders."
Will have to take a look at the system and see where the air is directed.
But thanks for passing on your experiences

Bizarre, yes it would direct extra air at the oil cooler. But wouldn't the oil be bypassing the oil cooler when then engine is cold ?

as above if the reliefe valves are working properly then the oil would be bypassing the oil cooler till hot anyway but as the air for the oil cooler on a doghouse shroud comes off a separate shroud at the back the airflow doesnt rreally change
the extra airflow is actually designed to go the the heater boxes when the flaps are shut for improved heating
