If you've read my whole thread then you should know that I'm planning a kammback for Berta. Coast down tests showed up ~9% improvement, so that's something worth to fight for. I can tell that hatch is too steep to have good airflow. It's based of an observation of water droplets which are not moving at all while driving. So there's no flow attached for sure. And when I've tested airflow over kammy it was just perfect. So my plan is to build kammy for Berta, and I'm hoping that will be soon, together with my custom coded MPGuino and smaller rear-view mirrors. I'm planning rear wheel skirts as well, and maybe a bellypan in the future.
So many ideas and so little time for realization.
