Would a few of you guys post your EGT's for J3300 engines? I don't have 6 probes and need to decide which pots are likely the hottest

Hope the figures below help. I have usually found that the middle two cylinders No3 and No4 are about 10 deg cooler.
Note the high EGT reading on No 2. This was caused by placing the sensor too close to the edge of the tube
Performance figures as at 1151 hours.
In cruise
RPM 2850
Oil Pressure 210 KPa
Oil Temperature 90 deg
Cyl No 1 Cyl No 2 Cyl No 5 Cyl No 6
CHT 146 deg 106 deg 140 deg 111 deg
EGT 683 deg 750 deg* 680 deg 660 deg
At idle
RPM 850
Oil Pressure 90 KPa
Oil Temperature 85 deg
Maximum Static RPM 2850
OAT 16.8 deg
Spats on for this test
Measured at Gallery. Add 100 KPa for corresponding pressure
• EGT dropped to 698 deg when probe repositioned to centre of Exhaust tube.
