average private/ builder quickly reaches his technical and financial limits. A few months ago during a flight test, I encountered one engine installation that could become one of the best power augmentation turbo kits for the stock 912 (80-hp) engine. The Italian manufacturer Marc Ingegno was, until 2013, known only as an aviation components supplier for things such as wheels, brakes, and gear/suspension parts. The metal processing company manufactures parts for fixedwing aircraft, military helicopters and jets, automobiles, and motorcycles. During the 2013 AERO Friedrichshafen, it introduced its first aircraft, the Parrot. Alberto Marchini, owner of Marc Ingegno, leads the company that is located in the northernmost part of Italy, close to the Swiss border, in the town of Varallo Sesia. The company has sold more than 50 turbo kits, which weigh about 22 pounds (10 kilograms), with the majority installed in aircraft and in daily use. I was able to test-fly the Parrot, which was fitted with the 912 engine and Marc Ingegno's turbo. The flight showed that the engine was delivering good performance, even in low density altitude in the Italian Alps. Almost all modern dieselcycle automotive engines and an increasing number of new gasoline engines on the market are turbocharged nowadays. The kit carries a complicated name, the MI8120PA00 REV0 Kit. It includes all needed parts for the conversion of any stock 80-hp Rotax 912 engine: • four-in-one stainless-steel exhaust manifold • turbocharger (Mitsubishi automotive) with waste gate for max 1.4 Bar barometric pressure (41.34 inches/ mercury) (0.4 Bar/11.8 inches/mercury overpressure at sea level) • silencer • air filter • two electric fuel pumps • fuel pressure regulator The air filter on the suction side and the oil return line with a small oil-tank below the turbo. Marc Ingegno's Parrot during the test flight is landing in a river bed in Italian Alps. EAA Experimenter 35
