I implemented exhaust extraction also in my Europa. No venturi, just the
exhaust tube shorter than the tunnel it is fed through. I could however
never establish that it is really working as designed. Fact is that I'm
unable to overheat the engine on the ground, but that can also be the
result of the completely different low drag cooling arrangement. Or the
Woodcomp propeller of course.
