I was reading in the latest edition of Sport Aviation about Tony
Spicer's Sonex. He uses a Jabiru 3300 engine in it and reportedly gets
great performance from the plane with that engine. An interesting
tidbit of information in the article was a comment that an improvement
to the 3300 engine has the engine putting out its rated h.p. at a much
lower r.p.m. The original figures put the 120 h.p. output at 3300
r.p.m. which most people figure is a little high as it limits the
diameter of prop that can be used, this plus most Continental/ Lycoming
drivers are used to seeing their r.p.m. numbers run several hundred
r.p.m less. I consider this engine improvement to be substantial, but
I can't figure out why none of the Jabiru dealerships ( and I think I
checked them all ) have no mention of this engine improvement. You
would think an improvement such as this would be front page news on
their websites. If the engine has been improved to this extent, you
would think their sales would increase. Their marketing gurus must be
asleep. They DID however, waste no time in getting their latest price
increase published. To their credit, though, they also list the new
h.p. increase of the 2200 engine from 80 h.p. to 85 h.p.
