Dear = subscribers,

When I run the engine lean of peak with a turbo temp = around 1650 degree (75 LOP) I get really nice results in regards to head = temp and IAS.

Studying the articles I understand that coming from = the lean side first the TIT peaks and then head temps will peak later = (means richer).

In case I = really want to go fast sometime and don’t care about fuel = consumption:

Can anyone give me a temp spread that I need to stay = on the rich side from the peak TIT in order to be on the declining rich = side of the head temp line and be safe?

Or is there = another procedure to run ROP and have nice cool head temps. The fuel = flow settings in the Continental for ROP operation make my head temps = slowly creep above 400.

Thanks for = your help

Ralf
