Remi,
I can tell you, that the 7-row oil cooler in my setup is sufficient under ALL
conditions.
That also (like many other things I've learned about cooling) is far
---From logical, since I always had the oil too hot in summer even in cruise
climb
90KIAS with the 13-row cooler (which I donated to the Europa Club :-) ) when
it was installed in tandem with the radiator previously.
Now I only left a gap of just 1 cm below the radiator with an aluminum sheet
installed
in the tunnel, so that I have in sum the radiator surface and this 1 cm
gap below, where all air has to pass through in the tunnel. The oil cooler has
now 4 rows overlapping behind the radiator and only 3 rows get cool air from
this 1 cm gap.
In addition the aluminum sheet in the tunnel, which guides the air through the
radiator extends behind the oil cooler, so that no cool air is lost below the
oil cooler.
