The drag racers like this because carburetors more responsive and 
faster off line and part throttle and fuel injection better at WOT?
At least that what Billy Mitchell and his injectorator say.
Also seemed to verify this when converting 12cyl. 12 barrel webers
to dual CIS, what a crime.  The CIS system was slush, the webbers
sounded like the engine just exploded.
In last days of carbs, FI always looked better at WOT but carb.
was better at part throttle and responded better.
Anything that helps atomization helps power, on dyno I was working
with a 1 barrel, so most benefits seemed to be in fuel distribution.
Best results was drilling holes in throttle shaft as venturi jets.
As stated below all in the atmoization.
