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 UL520iS engine corrected to the International Standard Atmosphere conditions at sea level.
The following graph shows the calculated available power of the UL520iS engine at different RPM settings, WOT (wide open throttle) and varying density altitude.
For more information on ISA, density altitude, interpretation of this graph, the conversion of the figures to actual atmospheric conditions, refer to the “Engine Resources” section on our website and more specifically: “ISA conditions & conversion”.
