Temp question

last weekend cooked a brisket, today I'm cooking a butt. I'm using/used the Weber extender rack they sell for the summit with a drip pan under the protein.

Qestion is, both times I've had to keep the bottom air vent much more open through the cook with this set up than I'm used to (usually air vents barely cracked open after a couple hours) see pic.

Last week I thought maybe my air holes were plugged so I took better care today and same thing. I did put water in the drip pan maybe that's keeping the temp down? Anyways it's been on 3hrs and this is how open I still have it - this ever happen to anyone else?heres a pic of my brisket from last weekend

    Have you taken the firebox out recently?  A few times, over the years, enough ash built up between the firebox and the wall of the Egg itself that it cut back on air flow.  Taking the fire ring and firebox out and cleaning the Egg out, then carefully putting them back solved the problem.

    Solid advice - that base is pretty new, got it in March after my old one cracked, so I doubt that's it

    A few things to consider- if your thermo is calibrated then believe your indications.  As you well know, the BGE is an air-flow driven machine so if you are needing more air there is a change in the flow path.  @Theophan identified a frequently overlooked issue.  Also I'm guessing the new rig has changed the air-flow dynamics.  
    The water-pan; it acts as a heat sink as long as you have water in the pan.  You need a lot of BTU's to convert the water to steam so that takes fuel consumption.  Should you run out of water then your temperature will naturally increase due to the air-flow/energy originally used to heat and evaporate the water.  FWIW-

    Pulled decent smoke ring wonder if the higher btu's/higher air flow at the beggining cause of the water pan helped that
