Hi Alister.
Your recent e-mail exchange on the Jabiru engine caught my eye. One of them
mentioned the 6 cyl engine churning out 120 hp @ 3300 rpm. On the
www.jabiru.co.uk/3300spec.htm site I see this engine rated at 100 hp@2750
rpm and the displacement being 3300cc. The 4 cyl version does run at 3300rpm
(80hp) and I would think the 3.3 liter can run faster than the 2750.
At 3000 RPM one could still swing a 74"dia prop. It woul reach about Mach
0.9 at the tip (about the same as the C172 seaplane 80" dia prop). I wonder
what the Jabiru 3.3 puts out at 3000, 3100 or 3200RPM and how robust it is
to take it.
If you find any info on any of this, please let me know. PAUL KUCERA , REBEL

Subject: Jabaru Engines
Hi Folks,
Just went down to the Aero Club bar for a quick one and the right chap was
there, he has used the jabaru engine and has researched them pretty well.
Apparently the earlier ones had no valve lubrication of any significance,
it didn't do them any good! Once they got that solved it was the end of the
problem, they are a very good motor.
They have changed the cylinders now so that the 4 cylinder is producing 80
hp (optional I think), up from the previous 60hp. It weighs 50lb less than
the 912 and costs a bundle of dollars less too (NZ$7000).
What may also be of interest is the new 6 cylinder version produces 120hp.
weighs the same as the 912 and is about the same price, not bad,I would
have thought.
I was warned to beware when comparing the specs of both engines to make
sure the weight of the Rotax includes radiator, coolant, reduction box etc.
Hope this helps.
