I'm selling my Valley Engineering "Big Bad Twin" (as they called it). It is a Generac big blovk (990cc) engine together with custom made Culver prop and custom belt redrive. The engine is brand new. I bought it to mount in my then project, but I now realise it is a bit too big. Valley Engineering, said that their 50hp motor turning a larger prop (which they supplied) outperforms the 60 hp direct drive vw, and it does so with a pretty significant weigh savings at only 29 litres per hour. Some information (from Valley Engineering) 50hp 9 litres per hour 115kg static thrust (250 lbs) 1000 hour TBO 990cc Generac industrial engine Weber carb Custom carb heat Custom exhausts (made by Valley Engineering) Electric start Alternator Oil cooler and filter Valley Engineering belt redrive with auto tensioner Custom wooden prop by Culver Props 52kg with oil in cranc, starter, alternator, redrive, oil cooler (verified by me) The engine is brand new, only run for a minute or so to verify starting etc From the lightsportaircraft website: "The "Big Twin" starts out life as a Generac generator engine, which Valley Engineering modifies with the addition of a specially designed intake manifold and carburation. With the low rpm and low compression, Gene estimates the TBO at 1,000 hours. Valley Engineering is offering "Big Twin" engine firewall forward packages which include a custom intake manifold, Weber carburetor, custom carb heat and a Culver propeller. The packages are available direct drive or with the Valley Engineering PSRU unit, and can be used both tractor and pusher configurations.
