"Having assembled a few motors that made in the neighborhood of 500hp and having grown up around drag racing, I am no stranger to high-performance vehicles, but I don't think I have ever driven anything that pulled so hard the first hundred feet... you really have to hang on tight! A (expletive) Rocket!"
(Quote from Roy LeMeur, NEDRA Northwest Regional Director, after driving White Zombie.)

Enersys (Hawker) and Aerobatteries continue with their EV drag racing support as a fresh shipment of batteries arrive for the 2006 racing season.
Removed the one year old 2005 season pack and installed a fresh pack of the same model 12 volt 26 ahr Hawker 'Aerobatteries', but added one more for a total of 30 batteries, raising the pack from 348V to an even loftier 360V! Total pack weight now at 735 lbs. The rear seat area tray and the sunken trunk tray were already stuffed full with no extra space for one more battery, so the 30th battery went to the area used during past changes to the car, the aluminum shelf just behind the rear seat back bulkhead. You can see the 30th battery in the photos above.
Zilla Z2k 2000 amp controller with Hairball interface. Programable automatic series-parallel contactor control. Quick-pull emergency disconnect.
Replaced the 16 ahr Hawker Genesis 12V battery with a new 16 ahr Hawker Aerobatteries type based on the same model. Retained the 12V port in trunk for connection to the removable Orbital Blue Top 12V booster battery (used up through June) for nighttime drives to and from the track. Due to the 30th traction battery location, the Orbital battery was relocated and secured to left side of trunk floor.
In July a specially made 40 amp DC-DC converter, based on a Vicor DC-DC module, was put together by Chris Brune. (left) The driver's side controller/contactor/throttle pot mount before the new DC-DC was installed. (right) The revised mount has the new DC-DC and associated components.
The heavy portable Orbital was no longer needed. The 16 ahr Hawker Aerobatteries 12V battery remained as the 12V system back-up.
Field weakening added with twin 300 amp GE contactors and activated via steering wheel thumb button. (left) In preparation for the field weakening contactors, a new aluminum mount was created and added adjacent to the motor. (right) Here's the completed field weakening circuit.

5-13-2006 White Zombie travels to Chicago area for the 'High Voltage Nationals'...rained out, no runs. Due to the wet pavement the front tires were not able to hold back the force of the traction tires, so we blocked the fronts at a Pep Boys parking lot in order to do a few burnoffs for the crowd.

At the Wayland EV Juice Bar, three Northwest Handling Systems mechanics check out Cafe Electric's hot twin motor Porsche 914... evidently, you have to have a gotee in order to work on forklifts! From left to right... Steve Starks who drove the electric Porsche at the track that night, Tim Brehm, and the vacationing Dave Burkhart.
In the pits with NEDRA dag racers and their machines. (center) David Brill among the fast machines. (right) The array of powerful Manzanita Micro chargers that kept all the electric drag machines juiced-up.
Blown (open circuited) battery on 7-29 on the last run. The photo below isn't pretty in any sense. At tech-in they noted we didn't have a separating piece between the trunk area and the rear seat area, so in a last minute 'mod' we installed a tacky-looking piece of red corrigated plastic sheeting held in with contrasting green duct tape...nice! Hey, it worked. You can see the effects of the blown battery and the bypassing cable we added around it. Also note that the center hold-down bracket for the pack is missing...it was after the races and just a bandaid fix so we could drive the car home.
