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, =20
                 Neil.

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
