after flying my sonex witch was equiped with a aerovee Vw engine and later on converted it into a 120hp turbo efi engine, i figured out the only way to gain better take-off and climb performance was to use a geared engine and a CS prop. So i purchased a 912UL-F3 engine and started fabricating a one of engine mount. I then started on welding a 4-1 turbo manifold and a injection intake system. I decided to go with and intercooler to cooler the intake air on hot days.
Im finally gettig ready for ground tests, only mounting of oilcooler and some minor details, and the transformation is complete.
For thoose of you who might be intrested to see my conversion, heres a link. You can scroll thorug 7 pages, and theres tons of pictures. The Norwegian wrighting migh be hard to understand, but the pictures pretty much tells it all.. ;)
