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 UL390iS engine corrected to the International Standard Atmosphere conditions at sea level.
The following graph shows the calculated available power of the UL390iS engine at different RPM settings, WOT (wide open throttle) and varying density altitude.
|Maximum dimension in X direction (length)*||723 mm [28.4 inch]|
|Maximum dimension in Y direction (width)*||654 mm [28.97 inch]|
|Maximum dimension in Z direction (height)*||472 mm [18.6 inch]|
