Walter A,

OK, On a cold day (1C) with the Baro at 29.93" and an airport elevation= of=20 700 MSL, I begin my takeoff roll slowly applying full throttle because of th= e=20 strong P-factor and all the other left turning tendencies in my motorized la= wn=20 dart.

Say about 1000 feet down the runway, WOT, at close to 80 KIAS I=20 see 1290F on cyl#4 EGT.

Rotate, shallow climb, gear up, flaps up and accelerating (about 1= 10=20 KIAS) I see #4 EGT at 1310F.

About 1400 MSL, in a stabilized climb at 140 KIAS I now see 1330F on #4= =20 EGT.

In cruise at about 6500 MSL, #4 EGT would peak at about 1420-1430F.

I will not be at sea level for quite some time, however I have seen 29.= 9=20 MAP as I accelerate to climb speed. Generally, my #4 target EGT is (and= has=20 been) 1290F.

1. Is that a good target or am I being to conservative?

2. If I wanted to use 1310F as the target, is there some a correc= tion=20 I should make to normalize the EGT to a sea-level value?

3. Am I being to anal? - Wait, don't answer that........

Once again, thanks for Power Pointing to the sample pp presentation.
