5,000-hp dragster
« on: August 03, 2017, 11:37:16 AM »
*electric* dragster

Fueled-engine motorheads have long had a problem with torque curve of an electric drivetrain.  

Good article, worth a read just for the physics even if you're not a motorhead.

Top Fuel class dragsters:
These giant, mutant, 10,000-horsepower fire-breathers suck down more than 20 gallons of nitromethane fuel over the course of a pass. Their ear-splitting, 150-decibel, open exhaust headers are angled upward, and they push enough gas to give the car an extra 1,100 pounds worth of downforce to help with the almost-impossible task of sticking its giant rear tires to the drag strip.

What sort of battery do you need for this kind of work?

It's centered around very high discharge ability. One advantageous consequence of that is fast charging ability too, but that's not a big practical consideration for us, because we have about two hours to turn the car around between competition runs, and we'll only need a few minutes to charge up if we need to push it. We'll have plenty of time to maintain and check over the rest of the car as we essentially trickle charge the thing back up.


I'd like to see the inners of that setup.
