Without removing the wrapping, put your turkey in a pan and place it on the cooking grate. Put the kettle lid on and use a flashlight to look through the lid vent holes to check clearance. As long as the lid sits on the bowl without hitting the turkey, it will be fine. I don't remember the largest whole turkey I have cooked on the grate but I remember the clearance between the turkey and the lid as being about 1/4".
