The EGTs will not necessarily be lower at lower powers, they may be higher! The issue is that the lower power is reducing the pressure and reducing the force with which the gasses are being forced out of the exhaust.

Hi George,
 
I copied your suggested protocol for turbo loss for inclusion into my checklists. I think it is a well reasoned approach to what could be a high risk-low probability event.
 
I was wondering if enrichening the mixture to further decrease the EGTs would be a useful adjunct to the protocol? Or do you think it would be better to lean to peak power and then further reduce the power setting to the minimum required? I realize that the temps will already be significantly lower as a result of the decreased power setting. Since many of my flights take me across the Rockies, precautionary landing sites are occasionally rather distant and beyond the gliding range of my aircraft. In addition, I just replaced the main exhaust component that supports my (single) turbo due to unrepairable cracks, so this topic is near and dear to my heart.
 
Best Regards,
Mike
