EDDLC- Course InstuctorThe Old Saybrook High School Engineering and Development Team will be Competing in the May 15, 2009 Electrathon Race at Lime Rock Park Race Track in Lakeville, Connecticut.
The race is run on an approximately 1/4 mile oval track with a 12-foot elevation change. The cars are electrically powered by two 12-volt car batteries. The winner is determined by completing the most laps in one hour.
We completed in our first race in October 2008 and finished 2nd place in the Novice Division, completing 88-laps. After the race the class discussed many ways to improve the cars performance including:
Improve aerodynamic by adding canopy, 2008 car was an open cockpit.
Improve battery performance, 2008 car used new unconditioned batteries
Redesign front end, 2008 car had no adjustments
Replace wheel bearings with ceramic, 2008 used $4 ball bearings
Improve paint job, purely cosmetic put inspirational
Provide alignment adjustment for rear wheel.
Replace drum brakes with disc type.
Replace throttle lever, 2008 car had a $5 rheostat.
Provide wireless motor monitoring, 2008 had none.
Monitor tire temperatures for proper wheel alignment.
Replace tires with 120PSI heavy duty tires, 2008 car tire had blowout.
Lower roll bar height for aerodynamic improvement
Lower vehicle center of gravity for better cornering performance
Rear view camera, 2008 mirrors vibrated and aerodynamic drag.
On board instrumentation: Voltage meter , amp-hour meter, speedometer
2-way radio, wireless headsets
