nitromethane is the WOW factor in drag racing; it is most likely the
#1 selling point of the NHRA full throttle series as we know it today.
no nitro = no fans (not racing, just not nat. events w/espn coverage)
or at least they wouldn't be on espn.
some sponsors would remain within automotive world; the rest would leave.
the smell, taste, feel and hear sensory overload of nhra drag racing is nitromethane, nothing else.
the IHRA would be much less without nitro as well.
PM is really cool, and the ADRL may pack stands, but they've done it with
free or very little admission - not sure they can dent NHRA's armour with
their current program (although i hope NHRA finds room for PM full time)
