Il s'agit d'un de fiabilisation des Jabiru qui passe par le remplacement des têtes de cylindre par de nouvelles têtes de cylindre refroidies par eau.
Le résultat des tests est impressionnant.
Water Cooling vs. Air Cooling
Water has more than 20x the thermal conductivity of air (ability to conduct heat).*
Water has over 4 times the specific heat of air (the amount of heat it takes to raise the temperature by 1°C).*
Opposed to removing heat from the surfaces of the head in a constricted cowl area, a water jacket, gives the ability to remove heat directly from around the hottest part of the engine.
Due to cooler heads, yielding no longer occurs, and is expected that head bolts will not need to be re-torqued.
*Applies to all applicable temperatures
