> Hi Bill an' Team;

Wow! I have been wallowing in the "You Tube" Killocycle runs awile.
AWESOME! And you are only 2 seconds from the Gas Bike record. I see the EV
Record for the fastest Bike on the Planet, in reach, now!Good Denver Post
writeup, too. Make ya feel that the American Sheeple are coming around.
"Isn't your father's golf cart" any more, the Kid DID say it sounds like a
golf cart? Has he been watching Rod's golf cart from Hell<g>?But he liked
it, there IS hope??

Re: [EVDL] KillaCycle at Bandimere Sat, Sept 1st (Best Burnout EVer)

Hi Ryan,

First, we are building yet another, larger, better, A123
Systems battery pack. Now that the motors are surviving, we can bump
up the HP output of the pack. We are planning to go 11 cells wide. At
75 C, this will be very slightly "over center" on the maximum power
transfer curve. At the maximum battery current of 1800 amps, the
Zilla will, (at least should,) not be able to draw the pack down to
half voltage. In theory, this should move up the power to about 475
HP. This is about 85 more HP than we are pushing right now. The extra
cells will add about 33 lbs, however.

We are also going to try out cell interconnects made of
copper, instead of nickel. Again, in theory, this should reduce the
resistance by about a factor of 2 (the geometry is different) and
should add about 6 more HP yet reduce the weight slightly. Every
little bit helps. :)

We will also start playing with the brush timing to find the
optimal settings. This will take a lot of runs and maybe a couple
burnt commutators.

What about those new, more powerful A123 cells? Are you using them yet?
