Holy bleep Bill, was that really 20 kW/kg? No slipping a decimal place or s=
omething? If it is really 20 kW/kg, wow... Let's put that into some perspec=
My stock V8 ice motor only is about 1 kW/kg
My buddy's racing V8 motor only is about 2 kW/kg
A top fuel dragster (the whole vehicle, around 7000 hp and 2500 lbs) is aro=
und 5 kW/kg
Let's see, suppose you did a top fuel dragster that was 1/2 of the weight i=
n these batteries... 1250 lbs would be 11 MEGAWatts of power! That's around=
Holy moly again! Bill watts the highest power you've tested out of these?
Holy guacamole, the motors in the motorcycle outweigh the battery pack!

Let's see if this post is OK.
We ran the KillaCycle today on our new 68 lb pack of A123Systems "F1" ce
lls. These deliver 20,000 W/kg.
We are in the testing mode still, and we have not yet completed the full bu=
ild on the battery pack, so it is just 274 volts. (We will complete the bui=
ld in the next few weeks and build up to 375 volts.)
We are "dialing in" the bike still. Today, Tracy Helmhold made a very clean=
pass (before the rain and wind arrived) and the bike ran the 1/4 mile in 7=
.621 at 170 mph. Tracy did such a smooth job that it looked easy.
Here is a video link to the run:
I especially liked how Tracy did the burn -out. Not more than I liked the l=
ow ET, of course. ;-)
We captured data from the Zilla for this run with Steve Ciciora's nifty "Zi=
llaSucker" data logger box.
