How's this for a basic Junior Dragster setup?

http://www.evparts.com/prod-MT2113.htm 6.7" Advanced DC motor $753
http://www.evparts.com/prod-CT1945.htm Alltrax 72V 450 Amp controller $782

6 each Enersys Genesis XE16 ~$130 ea = $780

(of course I'd throw in a contactor, breakers, fuses, 2/0 cabling and lugs which
I have surplus)

Total = $2414

72V*450amp=32.4KW or 43.4 HP

The torque would likely be in the order of maybe 200 ft-lbs

The track manager and Tech Inspector (married couple) have a junior dragster
chassis they bought and never used. Their daughter is too old now to use it.
They want a basic inexpensive ED JD to let the kids try out as a track
sponsored car.
How would the above work for a basic setup. What kind of performance should
they expect from a car outfitted like this?

If one were to upgrade to a Z1K-LV and run 144V @1000 amps would the
approximately 100+ ish hp kill a stock K91-4003 ?
