Airshares SR-20

My fuel flow, at 65% power, for my 200 HP T-Arrow is about 12 gph , but at 65%
power I cruise at 150 KTAS (or better - I plan for 150 tho) and can fly non-stop
for 700 NM - But this is also flying at 8000-13000 ft.

What's the fuel flow at 75% power? For a 200 hp engine, my guess is that
it's significantly more than 9 gph. Or conversely, it seems likely that the
9 gph isn't 75% cruise.

If I bought an SR-20 and it only gave me 130 kts at best cruise
performance,
I'd demand my money back!

Art didn't say 130 knots was his "best cruise performance". He said that's
what he gets at 9 gph. I assume he used that figure because that's close to
the fuel flow in a Cessna at normal cruise settings (with a 160 hp engine),
and so gives a rough apples-to-apples comparison between the airplanes.

First of all, 12 gph for 130 hp sounds to me like a lot of gas. I can get
the fuel flow on my 270 hp engine down to 12 gph at around the same power
setting (60-65%). You might want to double-check your engine gauges.

Secondly, turbocharging isn't a fair comparison (you as much said this),
since you get to enjoy full power operations at the higher altitudes where
true airspeed increases.

I have a shadin fuel flow monitor, it is pretty consistant with the airplanes
fuel flow gauge. I can lean it out more but that is best power setting. since I
only fly at 65% power, I dont want to lose what I have by skimping on the fuel
mixture. Plus this is a power setting, its not 65% due to altitude or fuel flow,
I set power (2400 RPM / 30" MP) for 65% then lean for best power.

the engine in the t-arrow is a cont. 6 cylinder, fuel injected, the normally
aspirated one is a 4 cylinder lycoming. why piper stopped making the T-arrow I
dont know, I think its alot better the the normally aspirated one (I have fown
both). But if it came down to buying a new airplane, An arrow or a SR20, the
arrow new is 271k (standard listing) - I think the sr20 would win out. Piper is
going to have to do something or cirrus is going to put alot of hurt on them and
other companies.
