Magnus effect in beamNG

Hi devs, @Joelvb and I were discussing aerodynamics in BeamNG and wanted to test the Magnus effect in beamng, in short: rotating objects cause lift (http://ffden-2.phys.uaf.edu/211_fall2010.web.dir/Patrick_Brandon/what_is_the_magnus_effect.html). This is used in some planes and even big boats.

Our setup:
The testcar without triangles, with a large spinning cylinder on top of that with triangles. We used the windapp to simulate the airflow when moving since our model was stationary in x,z (made by joelvb with ideas of us)
video about what happens:

according to the formula's, a 180 degree change of the wind direction should cause the cylinder to go in the opposite direction (-y-->y etc) But as we saw it, in beam the only thing that changes was the drag (wind comes from the opposite direction so the drag changes. the lift stayed the same.
I think it is because beam isnt simulating the airflow and thus the pressure causing the lift.
