I think you have not done the math quite right. A 5000 HP
battery pack made of off-the-shelf A123 systems M1 cells would weigh
just under 2000 lbs. If we use the prototype A123 Systems Ultra
cells, (they exist, but in very small numbers right now) this would
drop to something like 1000 lbs. A 7000 HP pack would weigh about
1400 lbs, leaving 1000 lbs for the motor(s), controller, and rolling
chassis. Not at all impossible, if one's pockets are deep enough.

If the electric racing world wanted to they could
build their own drag strip with a catenary overhead or
a third rail/ slot car strip down the center. Maybe
even a tessla generator/reciver and then we would see
electric racing times go way down. the top fueler drag
racers will do anything to get down the 1/4 faster,
none of which is practicle for street transition so
electrics could play that game too then we might see
some real competition.
