My ground speed exceeds 200k so often I don't even get excited about it! What I truly aim for is 168k TAS sipping 7 GPH or better! If I can find an altitude with a tail wind, all the better.

At what altitude to you get this speed/fuel burn, it is awesome.

I have had one small cross country trip so I was only at 10500 and was getting same speed or a bit better but at 8.2G, of course I had a nice tailwind and did reach the 200K club thru the ground speed

I finally was able to hit the magic 200+ Knot ground speed on the way to the Copperstate Fly In. This is of course only possible with a really strong 44 Knot direct tailwind, but it is in level flight with "Otto" the pilot at the controls. The green circle on the map is my "glide ring", you can see how skewed it is towards the North East. At one point I saw a 48 knot tailwind. It was actually quite smooth all the way out to Buckeye, AZ. I decided to enrichen the mixture a bit and see what the true speed of the airplane could be at altitude.
My usual 6.5 gph speed is around 147-150 Knots (LOP), so with 9 gph it was going only 8-10 knots faster.

Default Yesterday was sporty...

Yesterday was a wild ride. This picture was taken at only 3500msl. If I had climbed, I could have seen larger numbers but the trip too short to warrant that. I kind of wish I had turned around and flown a backwards ground track. I have never done that before. On return home the winds made for a non-boring crosswind landing...

Rejoined the club on the way back from IA yesterday:



Rough math shows 278mph, over 20mpg - and I don't have my injectors balanced yet and wasn't really leaned for efficiency.

Not bad for a 4 seat traveling machine that hauls whatever I stuff in it!

Haha - I had to google that, my Australian is a bit rusty!

I was running fast, just for the purposes of maximizing TAS to see how far into the 200kt club I could get. Max RPM for the IO-540 in the -10 is 2700...

Default WOW! T Short!

Congratulations! For a minute there I thought I was going to need to start the 300MPH club! Fantastic planes and Wonderful Tailwinds. Very Impressive!

Default Fast and Slow

As most of you know, joining the 200kt club in our machines is a regular occurrence. I was just out playing last week and with these crazy winds we've been having in the TN valley, I recorded my fastest and slowest ground speeds in level flight yet, with not a whole lot of effort.

FAST:



SLOW:
