Motor: 'Siamese 9' dual armature. Forced air-cooling added.
Drive type: Direct drive into Ford nine inch differential - no flywheel, clutch or transmission. Electric reverse.
Driveshaft: Single piece all aluminum driveline from 'Inland Empire Drivelines'. NHRA required Driveline loop.
Rear axle: Dutchman heavy duty Street/Strip Ford nine inch rear axle setup with 31 spline racing axles, & CalTracs traction bars.
Wheels & tires:Front - American Racing 'Torq Thrust D' 15 x 4 two piece alloys with 5 bolt Nissan/Ford bolt pattern and 145/65/15 Continental EcoContact LRR radials. Rear - American Racing 'Torq Thrust D' 15 x 8 two piece alloys with 5 bolt Nissan/Ford bolt pattern and 225/50/15 BF Goodrich 'G Force' Drag Radials' (23.9" dia.).
Batteries:192 Dow Kokam lithium manganese nickel cobalt polymer cells configured at 2P96S make up the Zombie's 355V, 21.3 kWh high current battery pack. With a manufacture date code of 2007 the cells are now 6 years old and have been in service since 2010. All cells are still performing 'as new' and are well balanced. They are 3.7V, 30 ah nominal with a continuous discharge rate of 20C, have a 40C 10 second rating for a maximum of 1200 amps from each cell, and are configured in paralleled pairs so the battery pack can safely output 2400 amps.
Controller:Zilla Z2k 2000 amp controller. Quick-pull emergency disconnect.
12 volt system: Twin unassisted (no DC-DC) 40 ahr Thunder Sky 13.2V batteries, each with 4 ch BMS boards. One is located under the hood, the other one is in the trunk compartment. With 100 miles driving range, 80 ah of 12V system battery power is needed to run things for hours on end.
Other Mods: Other than the rebuild of the drive motor and the addition of forced-air cooling, there were no new changes for 2013.
Car weight: 2364 lbs.
June 8th... Heads up 1/4 mile drag racing at PIR for filming of PBS Nova's 'Making Stuff Faster'
This is a casual 'unofficial' car show that happens every weekend fron the Summer through the Fall - the Zombie made several appearances.
None! From the hard lessons learned at the 2012 Tucson races, forced-air motor cooling was added. Everything worked perfectly throughout 2013, the new cooling system protected the motor, and there were no failures. Other than the one track event in June, the Zombie was not raced again in 2013 - though it was driven extensively as a street EV.
