Answer:
Poultry only needs to reach a temperature of about 165 C to kill all the harmful bacteria, so when it comes to deep frying wings anything around 350 F will be safe however you need to remember that the temperature of the oil will drop once you add the wings.
Here are some basic guide line to safely cook them:
Heat oil to 350-375 F
Don't stack more then one layer of wings in the deep fryer
Depending on the size of your deep fryer anywhere from 8-12 minutes should be fine adjust cooking time to taste.
if cooking above 400 F; 6-8 minutes will be fine.
watch the deep fryer carefully, once the bubbling slows down it means your running out of moisture in the wings and may dry out if you cook hem for too long after that.
Good luck with your deep frying.
