Hot Rod Your Grill

[Chris Hennes]

Over on this topic on fanning your coals member dougal mentioned the following anecdote:

Some drilled pipework was thus laid into the base of the drum, (about two inches off the base) with an external connection well outside the fire. Attaching the office vacuum cleaner to this - importantly the exhaust of the vacuum cleaner - did indeed dramatically speed up the lighting and establishment of a good grilling fire.

This got me thinking: has anyone out there "hot rodded" their grill, maybe for maximum heat output, or to make cleaning easier, or whatever? The most I've ever considered doing is adding a better thermometer, and I haven't even gotten around to that!
