Im sure there is a "formula" to work out what the limit is for an EV dragster is.
Its not just a matter of generating more power like the Fuelers do with chemistry and clever motor tuning etc...
..With electrics, you have to keep adding more battery and copper ( weight) and at some point the laws of diminishing returns start to hit home.
A battery pack capable of supplying 6 MWhrs for a few seconds would weigh well over 500kg alone, and motors with enough copper to convert those thousands of amps into torque/power, would also be no small weight.
So you start having to haul a ton of extra weight up to 300 mph...and stop it again !!
Anyone know what a current TF weighs ?
..Answer ..1000kg.. ( 2225 lbs minimum regulation, and most are close to it)
and their 500cu in motors weigh 230kg complete, ..so a rolling chassis weighs 770kg.
Add 6000kW of motors , controllers, and 500-600 kg of cells and i suspect you are now underpowered for the weight !!
Any one want to hazard a guess at the weight of a 6000kW motor ?
I hope that your friend has done his homework before he sinks any serious cash into this !
Meanwhile, for 1MW ..how about this..
