Hello Mark,
My 601 XL with a Jabiru 3300 and the carbon-fiber Sensenich prop is good for an
honest 140 MPH. It takes a minute or so to reach that speed. I dont do this
anymore because its too hard on the engine and fuel consumption is high (10 gallons
per hour or so).
My plane had performance problems early on. They all had to do with the engine
air intake system. The primary problem was the use of scat tube between the
airbox and the Bing carburetor. When I got rid of the scat tube I picked up a
noticeable amount of power.
What is your top RPM when you hit the wall? Presumably you would want the engine
turning close to red-line where it produces the most power. Again, I dont do
this to my engine anymore. I have lowered the red-line to 3,050 and the yellow
to 2,950 after getting a good look at the rod bearings at 600 hours and noticing
they were quite worn.

Steve,
My static WOT RPM is 2800 with the present prop setting. In flight, I get up to
3100 RPM but keep it at or below 2800 for level flight.
I expected that getting to near 140 MPH was going to take most of t he available
power. At least from your experience it is possible. I don't expect to actually
operate in that range too often but I would like to know what the airframe
is reasonably capable of.
Do you have wheel pants? External antennas?
At this time I don't have wheel pants, only one antenna, the ELT, and no entry
step. I have not cleaned up any of the gaps around the stabilizer and have done
nothing about the gaps on the control surfaces.
The engine is just finishing its "run in" period during which I tried to keep power
high but not above 75% except for climb.
I have given up on the Bing carb. I never got it to operate well at full throttle.
Jabiru's statement was that the problem was caused by the right angle bend
in the intake. Given that this bend was inherent in the Jabiru firewall forward
kit, I though this was not a good response. I also never liked a number of
things about the Bing, I never got the feeling it was a real aircraft device.
Did you have to replace engine parts or was your observation at 600 hours just
an inspection? Did you measure how much wear there was on the bearings?

Mark,
My plane does have wheel pants. I have a COM and ELT external antennas. I have
a entry step.
How do you like your TBI? My TBI will be here in 3 days.
At 600 hours I did a full top-end. More information can be found on my blogs on
the Zenith Aircraft Builders and Flyers site.
