For many, if not most, modern singles, 'save the engine' is a crock. At or near sea level, you're not likely to be anywhere near engine limits when you hit 100% torque. The TOT should still be in the green range, as should the N1. The transmission won't suddenly fly apart at 100% torque either. Pull what you need, and if you're heavy and in a confined area, 100% is what you need. Pull it in quickly, to get the aircraft moving upward, and hold it there until above the obstacles. If you're very light, pull enough to get the aircraft moving upward briskly, but it doesn't have to be 100% torque. Judgment is always necessary, so use some when pulling pitch. Always use enough, but never too much or too little. The boss pays me for my judgment, not for anything else.
