That intake looks open wider than I would expect. Hard to tell. Here is mine:
Mine seems to be settling in around 280* in 30* - 40* weather. I expect it to run a little hotter when the weather warms up.
Also, I think it all depends on where you're measuring the temperature. Taking a temp at one single spot doesn't give a full picture of what is going on. I'm still trying to figure out how the ribs don't get extremely burned being so close to the fire, but they don't. So, obviously the temp there doesn't matter.
