Drag racing goes electric
William K.   9/8/2011 10:23:08 PM
Back in 1968 we were working on the design of an electric dragster that would have a separate motor driving each of the four wheels. We had a source of motors that could deliver about 400HP "for a short time". We also had the battery problem solved, as our plaan was to have two copper strips, one on each side of the track, and use two large pickups. This would satisfy the track operators that the vehicle would lose power if it left the track. The power would have been from a large diesel powered generator parked well behind the pits area. the 4800 volts would drive the four motors in series, 1200 volts each, and around 200 amps. This car would probably have set many new records for any quater-mile car. The project ended when we determined that it was well beyond our financial capabilities. Also, some of the group got drafted. But it certainly would haave been quite a show to run it.

Please note that Design News Magazine has had a leadership position in its electric race tech reports, and has followed electric drag racing developments even earlier than 2007.  There was an article on the "Bad Amplitude" dragster developed by Net Gain Technologies, a racer in the style of a top fuel "rail job," back in 2002.  I am pleased to note that as a consultant to Warfield Electric Co., Inc., the motor manufacturer, I participated in the development of the high-performance, direct-current motors used in Bad Amplitude.  Design News had a nice write-up in the October 07, 2002 issue.  Please see the complete article at:  http://www.designnews.com/document.asp?doc_id=216569   This dragster had been retired for some time, but with battery technology advances since that time, Net Gain plans to reactivate the dragster project.
