AFAIK the big problem with an electric drag racer is weight/mass. Batteries are heavier than fuel. Electric motors are fantastic at acceleration, but you have to feed them with enough amps to make that happen.

A drag racer doesn't need range, so storing a large volume of energy probably isn't the problem. But having enough batteries to supply enough amperage to get that kind of acceleration is probably adding too much weight to be competitive.

This is also the problem with battery powered aviation. The majority of the energy used in a flight is on takeoff and ascent, effectively lifting all that mass to cruising altitude.
