I compiled a cheat sheet for the important things I always look up when it's time to fry a turkey.  How hot to get the oil and how long to cook it.  Please refer to the complete giudes at the bottom of this article for more details and precautions.

Heat peanut oil in a turkey fryer or a very, very large stockpot to 350 degrees F. Lower turkey into hot oil, very carefully, making sure it is fully submerged. Fry turkey for 3 minutes per pound plus 5 minutes per bird. Remove turkey from oil and drain on paper towels.
