Bone-in Turkey Breast Cooking Time Question

[NAR_Simpson]

I plan on cooking a 9 lb Brined Bone-in Turkey Breast on my Performer Grill around 325 - 350. I am thinking it will take around 3 hours, but not sure. Is there a way to calculate the cooking time?
I usually use my WSM for the Turkey, but I am doing Ribs on the WSM for Christmas this year. This will be my first Turkey Breast on the Grill and I am just trying to get an approx cooking time.
I will check to make sure it is done via internal Temp. Thanks in advance and Have a Merry Christmas everyone!

I'm doing one myself today also. I did one for thanksgiving and took about 2.5 hr.
