DC Plasma raced the Texas Mile today and ran a 134mph in the 1/2 mile and 155mph in the full mile. From a standing start. You can see the first uploaded video by Mike Dunn here.

Kind of neat from second 44 to 55 the jet engine sound of the run.

We ran at 210motor volts on the new helwig brushes.
Stock netgain motors otherwise. and a single zilla and half rated battery current at 1200 amps.

This is the run chart from the 155mph run. See the overdrive shift in the middle. We ran at 1200max amps on the battery where the factory rating is 2500amps max.

Hi John,
Could you email me the hex file for this run. I looked at the 1/4 mile file you sent earlier: the motor current and voltage work out, but I don't have a good handle on battery voltage yet. The internal resistance must depend strongly on battery temperature. I'll post graphs soon.
Gerhard.

Do you monitor battery temperature? If so, can I see the numbers.
Work has me crazed, but this project persists.
