This is the legacy vehicle, Speed Racer. LAAE felt
that Speed Racer was not through with its racing life
though, and the Academy pulled it out of its retirement.
Below are a few changes that were made so that Speed Racer can run in
Disk Brakes: One of the most esential
components. Has multiple effects that can change the
whole race. helps the driver make quick turns. Made out
of titanium. 160mm brakes. Must have a specific diameter
shape. Want round but not for the to bounce.
use aztek disc brakes. We had a disk brakes malfunction
because of fatigue and the force rthat was on it. and we
are getting new disc brakes use. Ran sufficient. Much
better. Using for the oregon electrathon.
After some research,
the students of LAAE discovered that the old drum brakes the vehicle had were not made for
stopping the vehicle. They immediately set out to change
this and installed disk breaks onto the vehicle.
Spindle: It is where the tire connects to the
rim, holds the tire to the car. Steel bar, threaded on
one side, keeping the castle nut in place,
The spindle was changed
becuase of the new brakes that Speed Racer had received.
The old spindle was not going to work with disk brakes.
Rear Axle and Motor(kev w): kev looked into
buying new motors. the problem was not enough horse
power. an increase of 1 horse power. when combined with
new gear ratio, the car moves faster. The rear axle
that Speed Racer had before had become stripped and was
no longer usable. The same applies to the motor that
Speed Racer used to have. (paul)
Gear ratio: LAAE's students conducted some
research to find what the best gear ratio between the
motor and the rear wheel was. Originally, the ratio was
6:1, but was changed to a 5:1 ratio. (Kev W.)
Batteries: -The driving force of the
vehicles, the batteries are possibly the most important
component in defining the performance of a car. They
have limited effective lifespans, and vary widely in
weight, capacity, and performance. Many models can be
considered sufficient for our purposes, but there is
often more to consider than raw factory specifications.
-Speed Racer has undergone
several heart transplants throughout its tenure. It was
christened bearing the traditional Optima YellowTop™ in
a 24-volt configuration. As new technologies arose, the
Optimas were exchanged for a set of Power Sonic
PG-12V55 FR long life series, which the most recent
vehicle, Volt, inherited. The picture above features the
third installation of batteries, the Odyessey PC-925.
Because this type is so lightweight, the vehicle was
able to accommodate 3 in a set, resulting in a 36-volt
configuration. Today, Speed Racer is sporting a 24-volt
set of Odyessey ER-40 (aka PC1100).
-Why all of the changes? Our choices were influenced by
several factors, including race legal weight
requirements, the lifespan of the batteries, and the
availibity of their replacements. Our Electrical Team
carefully and consistently regulates each pack's
discharge and charge cycle to develop their effective
output capacity, so whatever the case, we are race
