As the pressure dif goes up, the compressor works harder, the IAT goes up, the EGT and TIT go up.

thanks Lynn for the very complete information.
That's a good data point.
Please let me know if you get data from a higher altitude flight - one theory
is that TIT's run higher at higher pressure differential.

Here are the figures from one of my flights a few months ago:
17,570' Altitude (20,090 PA)
IAS - 195 KTS; TAS - 265 KTS
Induction air temp - 84 F
Manifold pressure - 29.5
RPF - 2490
Fuel flow - 18.9 GPH
TIT # 1 - 1620 F
TIT # 2 - 1576 F

EGT CHT
1. 1456 1. 334
2. 1415 1. 335
3. 1451 3. 310
4. 1421 4. 301
5. 1425 5. 316
6. 1424 6. 315
