Listening to the talk in the Vid, it seems the sanctioning body is limiting them to 10% increases in power.
What would TV Tommy do with this today?
I could see two 200 HP motors up front and two 400 HP motors in the rear for a "AWD". These motors can go from 0 RPM to 45,000 RPM in seconds.
1600 HP gas does not equal 1600 HP electric due to torque spread and RPM.... You'd spend more just for the controllers than the batteries.
But at this level you would need two trailers. Like said above 1 trailer with a huge (JP-8) Turbine generator and the second for servicing, spares and the dragster.
