Bob:
I watched both trucks make several passes.  My impressions were that the
Phoenix (I think that's the green 1942 that you mentioned) does a
significantly better job managing back-half airflow, and the red truck
seemed to be injecting an amazing amount of fuel (thus the big black
plume).  Seems I remember someone saying that the green truck is a
Detroit (2-stroke).  Can't remember what the other one was.
I suspect both those vehicles are capable of kicking-up a substantial
"roost" from tire spin at high speed (and Phoenix is reported to have
previously been plagued with tire trouble).  However, I don't remember
identifying tirespin from the salt pattern behind either of those.
Either I was just too caught-up in spectating that awesome sight (from
the TV, you can't imagine the impact these things have on you in
person)-- or the salt pattern from the tires might have been obscured by
the substantial turbulent plume behind these trucks.
