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

The power and torque curve of the engine has been established by repeated dyno tests, which were performed at sea level and in weather conditions close to the ISA standard. The following graph shows the real, available power and torque coming from the crankshaft of the UL520T engine corrected to the International Standard Atmosphere conditions at sea level.
The following graph shows the calculated available power of the UL520T engine at 2700 RPM setting, WOT (wide open throttle) and varying density altitude.
|Maximum dimension in X direction (length)*||847 mm [33.34 inch]|
|Maximum dimension in Y direction (width)*||744 mm [29.28 inch]|
|Maximum dimension in Z direction (height)*||551 mm [21.69 inch]|

The specific fuel consumption is 0.3l/h/HP (0.08USgal/h/HP).
Depending on the type of aircraft, personal style of flying,…, the average fuel consumption during cruise is 33-41 l/hour 8 -11 USgal/hour).
