Jabiru 3300 Power settings and fuel consumption

Postby MHaines » Tue Aug 23, 2016 3:09 pm

Greetings all;

I am new to this group and new as a Jabiru owner so please forgive any and all of my ignorance I may show.

I have a Zodiac 601 XLB with a Jabiru 3300 installed. I would like to know what the cruise power settings are. I believe the proper setting is 83% (100 hp) for cruise. Which, if I am correct, is achieved at 2,490 RPM at seal level. I would like to know the appropriate 83% power setting (or proper cruise power setting if not 83%) for higher altitudes like 5,000 and 8,000 feet.

I would also like to know what the normal fuel consumption is at various power settings. I know I have seen this information before, but I cannot seem to locate it now.

Any and all help will be greatly appreciated

Thanks,
Mike

Hello Mike,

Max continuous for your engine would be 3300 RPM (shsould deliver 120 HP).

I have cruised on a J400 equipped with the early Jabiru 3300 (big heads and solid lifters). It was comfortable at 2900-3100 RPM at 4-5 thousand all day and two up, it seemed to require around 22-24 lts per hour. The 83% should be based on the Max continuous RPM which is around 3300. Therefore, cruise RPM should be around 2750. I would add that the jabiru engine, according to various reports I have seen, produces a high level of harmonics around the 2300-2400 RPM therefore it is advisable to run it a little higher than the known problem RPMs.
