If I took my tuning plates out I would still have a 12" shadow plate jut above the throat but I feel sure I could get flames to just touch the end of it. So I would say about 500*
Making memories!
Current Smokers: Backyard RF Offset and Hybrid RF Offset trailer rig with Cowboy cooker and fish fryer, always room for more........
I have no tuning plates or deflector above my throats opening. My first Smoke, I saw temps at the FB hitting 415ish. That was one chimney of coals and 2 quarter log splits. Lost a few otherwise tasty wings to that inferno. Lessons learned.
