Dear = subscribers,

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=92t 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.
