Tried to mount the EGT probes as close as possible and same distance from the ports. However, at high power I'm seeing as much as 120F higher on rotor 2. Exhaust gas from rotor 1 passes by rotor 2 exhaust port so I'm wondering if that somehow increases rotor 2 EGT readings. Caught my attention today when EGT2 got above 1,800F at 6,200 RPM and 161 mph TAS @ 3,300' density altitude. Any of you that's using the stock exhaust manifold run into this?
