The UL520T is a 220HP aircraft engine manufactured by UL Power in Belgium. It is a direct drive, flat six boxer layout, featuring modern fuel injection and engine management ECU and turbo normalising.
It is based on the well proven UL520 but with a turbo charger / normalizer The main goal of this turbo is not to create a big boost in HP but rather to compensate for the loss of atmospheric density during all phases of flight, and thus eliminating the loss of power seen with elevated altitudes. The UL520T maintains its 220HP from sea level up to 15000 ft.
Airmaster make a number of propeller models for this engine.
