I remember an electric drag bike that ran a 20 amp motor and 8 marine deep discharge batterys !! 6 seconds and 180mph thru th' 1/4 mile , it had to be pushed or carried back and could not run again till th' batterys were replaced as th' 1st set were complety exhausted !!

This is ~300Kw, for 8 seconds 2.4MJ. Similar to other comments, at 24V you'd need a stupid amount of current, even at 1000V (dangerous) you'd still need 300A. This is why drag vehicles use liquid fuels like petroleum, e.g. you'd only need ~50-100ml gasoline to produce the same amount of energy. L

Here's a better link with some details.
And here's their website. Sorry this is so strung out but since we lost the text buffer it's harder to do searches while answering.
I think the drag of the extension cord will take off about 100 hp. So it'll need to be 500 bhp to get 8 sec.
