KAB Owners - Burn Rate

NPHuskerFL

I'll be doing a Chucky later this weekend L&S so that'll be my KAB first L&S. I have no doubt it'll be  fine. I'll load it up just like normal which will be over the top of the KAB but like I had discussed with Chad on the porch at the GA Mtn Eggfest and it'll be fine. No reason to over think it. I'll give an unbiased review after I do this. I have no doubt I'll be satisfied.

Not to hijack this thread but I'm curious to see how you do the Chucky and how it turns out.  We bought a 1/2 of beef earlier this year from a local farm with another family and we got a few Chuck's from that.  I haven't done anything with those yet mainly because I've never done one and not exactly sure what to do with them yet.  Any pointers will be greatly appreciated.

Back on topic, I've done 3 L&S cooks with my KAB, one being a 13 LB packer and it performed just as expected with no issues.  I ended up using my DigiQ for temp control as it was an overnight cook and I needed sleep that night but before I turned it over to the DigiQ I had been running stable at 275 for 2-3 hours with the bottom vent at normal setting and my Smokeware Cap just barely cracked.  Your results should be just as normal as before.

I think some of you are thinking you have more airflow, when what you really have is better airflow.  If you truly had more airflow then you would be at higher temps because airflow directly relates to lump burn rate.  If anything you should be closing your vents slightly more to compensate the better airflow through the lump.  If your vents are open the same as before the KAB and getting the same temps you used to then the KAB is not doing anything for airflow.  Scientifically there should be no difference in how much is burned, because X amount of airflow will equal Y temperature. I think others that have said that you just add less because of how the KAB sits in there are more likely right

This is pretty much been my experience.  There are slight differences in vent settings but it's not that noticeable.  I do notice that I get to temp quicker, especially when we're talking about high temp cooks and on high temp cooks I notice now if I want to maintain something like 600 degrees, if I don't start reducing airflow from the bottom vent it just keeps climbing where before I just pretty much left it wide open and maintained.

"X" amount of lump will have "y" amount of BTU's. 

"X" amount of lump will require "y" amount of oxygen to combust or liberate those BTU's.

A KAB does not change that. So it really becomes a Time/Speed/Distance kinda thing.

As @Mattman3969 has said a KAB changes one variable so you'll need to adjust another variable (vent settings) to go the same distance.
