Yerds, I think you mixed two of the points... the comment on the 747 was in relation to fuel consumed at the same rate and producing 25% less energy.... true, we don't know exact details of what the comparison was against for the fuel consumption statement.... But the dragster is still an AWESOME thing to watch.....(with earplugs on!)

It takes just
15/100ths (0.15) of a second for all 6,000+ horsepower (some
believe 8,000 HP is more realistic - there are no dynomometers
capable of measuring) of an NHRA Top Fuel dragster engine to
reach the rear wheels.

Under full throttle, a dragster
engine consumes 1-1/2 gallons of nitromethane per second; a
fully loaded 747 consumes jet fuel at the same rate with 25%
less energy being produced.
