Austin,

What was your fuel flow at takeoff?

Im back working on my IR so we were flying all day today.  Seein 28 gph on the roll I got CHT's @ 400 (with my spark plug probes so really more like 375, 1200 fpm with oil temps @ 209.  OAT was 60F.  The plane definately likes cool OAT's.

Thanks for the update.

28 GPH sounds low...My 210 hp (about to be 220) M20K takes 24ish...

Heck, I think a Bravo (with lesser horsepower) is something like 30-31 GPH on takeoff.

13 point something isnt bad @ 180kts!

Parker -  When I took ownership of 8DF the fuel flow on the roll was only 24.5 or so and it got hot quick.  It likes 28.  Rocket recommended 27-29gph.  The previous owner used to "kick on the boost pump @ 400agl" to keep the engine cool.  Explains why there were 4 cracked cylinder heads when we overhauled the engine......

Knowing that my CHT probes read 25F hotter than actual I still try to keep the CHT's @ 400F Max on the climb.

Basically the fuel pressure was set "by the book" in reference to the Continental manual.  It doesn't work in the Missile.  With no cowl flaps the only way to cool the engine is with fuel.

Yesterday I flew to Kerrville to drop off 211ZN at Dugosh for her annual.  I climbed out at 500 fpm, 2500 rpm, wot to 14,500 msl with the starting OAT 85 df.  She maintained the climb easily as I averaged around 140 tas.  My hottest CHT was 328 and my oil temp was stable at 216.  Once enroute, I ran her at 2450 rpm, wot (18" mp), and leaned to best power (12.3 gph) for a TAS of 180 kts.

You were able to make 18" @ 14,500?  That's better than I can make with a fresh overhaul.  I know you recently topped your engine but that's some animal you have.  Ive only climbed to 10,500 and the most I could get was 20.5".  Does your Missile have Ram Air?  Rocket said that it is worth about .75".....

[AustinChurch]

I have noticed that I get a little higher MP than I thought I should have so I had the MP guage checked during my pitot static checks and it is reading accurately.  I'm not sure why it breathes so well since I do not have the Ram Air feature. Maybe you should have your throttle linkage checked to ensure it is opening the throttle intake valve all the way.

The best Mooney is the one you can afford to buy.  If you have the plane that you intend to keep indefinitely, then the upgrades that you choose (GPS, paint, interior, performance upgrades) are worth it.

Resale is important: but, like the crash in real estate values in the past 5 years, it only matters if you're in a house that you want/need to sell. If you're in your permanent home (on the ground or aloft), then 'tart' it up to match your needs and desires. Life is short: enjoy it.
