The limitation on a drag car's speed certainly isn't engine output - Its traction. Top Fuel dragsters ride the clutch (makes it slip) for the first few hundred feet to keep the wheels from breaking loose. The clutches are replaced every run. The 8,000 Hp isn't even needed till the car reaches 100Mph or so, when the wheel RPMs get up and wind downforce increases traction. And it is at this point when an electric motor starts to fall off - they make all their power early on, when it can't get to the ground on a top fuel engine.
In fact, dragsters have a knob on the top the engine to dial out a couple hundred horsepower if the crew thinks traction will be a problem.
These batteries may very well make electric racing cheaper and more viable, but I doubt they'll help speed much. Less weight = less traction, too.
