No. Engine manufacturers differ in their approval of operation at peak EGT. In general, Lycoming recommends operation at peak for power settings of 75% and less while Continental recommends operation at peak for power settings of 65% and less. Other restrictions apply to some special engines and to some special conditions. Consult your Pilot’s Operating Handbook or engine handbook for specific details.
