The UL520T is based on the well proven  UL520 but now with a turbo charger
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.
An ASTM compliant version (with dual ECU) is available as well.
