Jeff,

Why do you run at 2400 RPM? - I usually run at 2500 RPM. This makes you
a little faster.

CHT 394 seems a little high - I try to keep them around 375 -385. What
is your TITmax and do you remember at what TIT did you run? I usually
stay 60 to 70 degree below TITmax on the lean side.

In cruise LOP my cylinder #1 and #2 are the warmest. Most of the times
#2 is slightly warmer.

If I want more fuel flow / speed without increasing TIT and CHT
increasing the MAP works for me - sometimes I go up to 34MAP - this way
I can get fuel flows of around 19 with CHT<385 and TIT  below 70 of
TITmax - this really makes the plane moving fast.

Ralf

Power and Flight parameters from today's flight test.

Level FL240 west bound: 15*F (IAS+41F)

MAP 31.5=09
RPM 2400
Fuel 17.1 gph (LOP)  FP 30
TAS 257
LIAS 174
High CHT 394 (#2, of course)
Cabin Altitude 10,000' (PSID 5.0)

If Fuel 18.1 gph, speed increases TAS 264 but CHT increase.
