I previously owned a 320 (N10ZC) and flew
over 800 hours all across the country. I Echo the fly high to save fuel
statement. I don’t have the calculations but if I remember
correctly I could pay for the oxygen equipment in less than a year and that was
at $1.70 per gallon (1994) prices! Its been a few years but I remember
the plan loved the 11,000 to 15000 FL range. I also recharged the bottle
from my companies welding bottle using a braided transfer hose. I’ve
got a Oxygen bottle with carry case and pulse ox dispenser for sale if anyone’s
interested…not needed now that I’ve got a 4P.

Subject: [LML] 320/360 efficiency
( was Lancair IV-P long term availability?)
<<If the surfaces are straight, true and
clean, then the 320 will cruise at just a little less than the 360 on a lot
less fuel, if what I read is correct. Sometimes I wonder if I needed to
do the KISS thing and just go with a 320 and the basics, and put the money into
optimizing the basics. Any comments>>
Getting the greatest efficiency out of your Lancair
requires the discipline to throttle back to your best range airspeed for
your given altitude and winds. The 360 and 320 will show little
difference, if any, at this point since both will be producing the same power
and I doubt the BSFC values differ much between the two. Throttling back
and reducing speed is not easy. We all like to see the highest
possible TAS. In general, fly high, really high.
The primary benefit of the 360 is the better
climb rate.
