|Location||Portland, Oregon US map|
|Vehicle||2010 State Champion Electrathon Aluminum frame |
This is my new car I built. Biggest
difference is the new back end that sweeps
in, and the two piece nose.
|Motor||Briggs and Stratton ETEK motor Permanent Magnet DC|
This is a real ETEK motor. Original is
|Drivetrain||Rear wheel drive. Has 35 pitch chain to |
drive the rear wheel.
|Controller||Alltrax AXE 4834P |
Got off of eBay as lightly used. Choose
model to change settings if needed.
|Batteries||2 Optima Red top 75/25, 25, 35. Yellow top D75/25, D35., 12.00 Volt, Lead-Acid, AGM|
There are actually 4 batteries; 2 for
practice and 2 for race.
|System Voltage||24 Volts|
Found on Craigslist as used. Put
stereo cable with gator clips to hook
up to the batteries. I'm really pleased
with the Iota charger, it works really
well for what I am doing. To charge up
a discharged set of Yellow tops after a
race takes a little under 4 hours with
the voltage jack plugged in.
|Heater||Trust me, if you racing in electrathon, |
you get heated up by
all of the excitement during a race!
|DC/DC Converter|| None|
The Cycle Analyst is wired into the
Alltrax controller and 200a shunt running
off the racing batteries.
|Instrumentation||Cycle analyst HC-LS version.|
|Top Speed||46 MPH (74 KPH)|
Depends on the track that dictates gear
ratio. Most tracks with lots of turns
and some hills is 25-30mph. The 46mph
was achieved during practice at
Portland International Raceway (PIR)
using the lowest gearing I had.
|Acceleration||Never tested it before. Depends on if the |
Red tops or the Yellow tops are in and
what ratio is in the car.
|Range||20 Miles (32 Kilometers)|
Depends on how fast your going and if your
throttle wisely for the hour long race.
|Watt Hours/Mile||I actually need to move the speedometer |
sensor to the back wheel, originally on
the left front wheel.
|Seating Capacity||1 driver, if driving slow; one person can |
stand on the back of
the car on the rear wheel supports.
|Curb Weight||300 Pounds (136 Kilograms)|
Unknown, I've yet to weigh the car. And it
depends if the car has Red tops or Yellow
tops in it too. I'm guessing somewhere
|Tires||Three Maxxis Hookworm 20"x1.95". Tire |
pressure at max on
|Conversion Time||About 6 months to get all of the parts. |
About 8 weeks in the
summer to weld a frame and have the car
power. For the second frame, about 2
|Conversion Cost||About $1500 for the first car, about $1000 |
for the new frame (I took the parts from
the old frame, David Douglas High School
put their own electrical parts and wheels
on the donated frame.)
|Additional Features||The car has a rack and pinion steering system (thanks to |
Kirk for the help you have
been.) Built form aluminum electrical conduit tubing
consisting of 1" OD and 3/4" OD, 1/8" and 1/16" aluminum
plate. Has a Simpson 5-point racing belt; cars have
before during races. 2 Avid
BB7 disc brakes on the front wheels. Car configured as a
cycle-car (2 wheels in the
front, 1 in the back.) Rear wheel drive. Speedometer now
located to the rear wheel for more accurate speed and
results. Really fun to
drive. For the lap counting device called the
each one is numbered. Mine happens to be numbered 59 :]
the 2010 racing season with my new car, car #59
finished in first place in the Northwest racing series.
