Zwaki,
Before you make any big changes try putting some spacers between the bottom of
the cowling and the fuselage to increase the gap for the air to exit the
cowling.
The Europa was first designed without the firewall behind the engine. As such
there
was no restriction to the exit air. After the firewall was fitted the exit
area was considerably reduced which reduces flow through the reds.
I found a several degree reduction in temperatures after increasing the exit
area.
It is worth a try.
