Nope.  Hydrogen has high energy, but the amount of
hydrogen in a hydro-carbon is closely related to the 
number of carbon atoms.  Example
     H     H      H
      |      |        |
H - C ... C .... C -H
      |      |        |
     H     H      H
for paraffin's like methane, ethane, propane, butane etc and then it 
gets complex.  Generally speaking the amount of H is aprox 2x the
amount of carbon atoms - but this still is a very low mass compared
to the carbon mass.

Since the hydrogen is bonded to the carbon ( coal and H2 if it were
not), it is very convenient to only look at the carbon content for most
purposes. 

For a discussion about fuels, in particular with regard to your need for
speed, check out Jeff Hartmans book "High Performance fuels and 
lubricants"

EFI content - Jeff is a strong advocate of a SECOND EFI system that 
piggybacks onto a tweaked stock system and injects a second separate
fuel that could be as radical as Nitromethane on demand.  Check out
chapter 14

"When some one gets something for nothing -
             some one else gets nothing for something "

If the first ingredient ain't Habanero, then the rest don't matter.
