Finn,
              I spent too much time with EGT's.  I kept worrying myself to death as the temps got to 1800 degrees.  Was told they should not get over 1600.  Kept in touch with another bloke who had no EGT's and when he finally pulled his engine apart --- no damage whatever.  Whether he managed to run cooler ???
Now fitting turbo and the EGT probe will be after the turbo.  That way I will feel much better?? If cooler readings
Regards,  
                 Neil.

Subject: [FlyRotary] EGT probes location

So, I'm using the Renesis stock exhaust manifold.

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?

Finn
