It
is clear that our tires will not last the weekend, so we decide to
put a new set on now. I will warm these up carefully, then run one
hot lap, followed by a cool down lap, in order to have fresh scrubbed
tires for the race. |
|
We
are focused on the getting the best possible result for this race
rather than the best qualifying position. Having already completed
a 14 lap race at 300 amps,
what we need now is a better idea about how much power we can run;
that is, data on how many Watt hours per mile we will use at 350
amps.

In
the Savanah race, we hit the minimum voltage limit after using 30.644
kWhrs at a 400 amp discharge rate (200 amp adv). With 1.5 kWhrs
used in the pace lap and cool down, we are left with 29.144 kWhrs
to race with. This means we need to average less than .925 kWhrs
per mile.

|
We
wait until the other cars in our group are 3/4 way
around the track on their out lap. I have a nice clear track to
gently build heat into the tires.
|
|
Since
I am still breaking in my tires during my first timed lap, a Spec
Racer high sided on the exit to Turn 2 does not effect my lap time. |
|
I
catch a safety truck in Turn 9 which ruins the start of what is
suppose to be my fast lap.
It
turns out not to matter as a Rabbit spins 180 degrees in Turn 3-4
and the car I am closing on, plows directly into him. I stay on
the brakes a little longer, tighten my line and avoid the smozzel.
'Black flag All' brings us into the pits.
