Does rolling coal damage catalytic converters?

Please excuse me for interrupting the thread but I have a question. What do the guys do to their trucks to make them belch out the black smoke. Is it some modification to the engine or a particular way they rev the engine? I've seen trucks that do it but I don't know how they can do it.

They actually allow that in VA, MD or wherever you are?
Here State really clamped down on that, and rightly so.
 
How much coal? I find it hard to believe a 1.9 liter jetta is going to black out an entire lane of traffic.

It will. You should see Golf II 1.6d (no turbo) when injection gets messed up. Holy moly.

A smaller engine can black out the sun when overfueled.

It's mechanically or electronically altered to overfuel the engine. When a diesel runs very rich, the partially burnt and unburnt fuel makes a cloud of impenetrable black smoke.

Mine did, without a tune. Happened the first time I drove it after fixing the turbo to make boost again, and immediately sucked in all the oil pooled in the intercooler. Solid black cloud that completely covered the entire road for about a quarter mile.

It's usually done via a chip tune that intentionally makes their truck run like garbage to TRIGGER THE LIBS (and put a salve on their own incredibly fragile and easily wounded masculinity)

I guess I'm old, I see no point in doing it.
