I prefer to cook low and slow so the majority of my butt cooks are done around 225 at the grate. I routinely have Q buddies who do their butts at a similar temperature and they're done in a much shorter time than mine. For instance, I regularly have 8 lb butts go 20 hours. Length of time isn't an issue for me as I prefer long smokes but I was just curious in other KK'ers experiences.
I currently have two 8 lbs butts on and they've been on the cooker almost 17 hours now; one is sitting at 184 the other 174. I've attached my Stokerlog at 16 hours for reference. Note I let my KK come up to temp "naturally" and at about the 15 hour mark I bumped the temp to 235 (got to love doing that from the comfort of my office).
EDIT: Thought I'd add that I'm running 8 lb 14 oz of Rancher on this cook.
EDIT II: Updated with an 22 hour graph, removed one butt @ 19:30 and second at 21:00.
EDIT III: Now that butts are done I'm going for "show" to see how long 8 lb 14 oz of Rancher will burn. Outside temps have been cool, overnight mid 40s daytime high high 50's.
EDIT IV: Ok, this is getting a little ridiculous, 25 hours and she's pegged at 235. May have to pull the plug soon, got a big day tomorrow.
