Gearing up for Friday

Stephen Johnsen created this fine design for Friday's little get-together.  No great expectations, as I know that Karmann Eclectric's battery pack is the weakest link, but I haven't had a timed run on record with the motor wired in parallel.  I've also picked up a pair of 205/75R15 tires, which will add 6.7% to the tire circumference, and requires 50 fewer revolutions to the mile (or 12 fewer to the quarter-mile).  At a minimum, it should improve trap speed from 78 to 83 mph.  If we get into the 14 second range, it'll prove a rousing success. 
Last item before the race is trying to add a remote to the differential locker, as it's a pain to keep crawling under the car to reposition that pin! 

Update: It's apparent that the batteries are doing all they can, and tinkering with the other pieces is doing little to nothing.  HowEVer, the car ran reliably and consistently, with all four runs within 0.5 mph and 0.4 seconds.  79.9 mph and 16 seconds is where she'll be until new batteries can be installed.
