NEDRA Classes, Voltage Divisions and Record
Rules
To earn a NEDRA Record vehicles are
categorized by Class and Voltage. Classes are determined by the extent
of the vehicle's modification from daily drivers such as simple Street
Conversions (SC) to extreme racers such as electric funny cars
in the Extreme Street (XS) class. Voltage Divisions range from
24 volts to over 348 volts and are represented by letters from A through
J.
Examples:
A Street Conversion running at 144
volts would be categorized as SC/E.
A Modified Conversion running at 348
volts would be categorized as MC/A2.

Voltage Divisions
Voltage Divisions from 24 to over 400 volts are designed to give
racers of all voltage ranges a chance to earn a NEDRA Record. You can
determined your voltage range nominally or more precisely with the "measured
voltage" of your vehicle.
Measured voltages allow racers with battery chemistries other then
12 volt lead acid the ability to obtain their correct votlage. The measured
voltage is not the "float voltage" but the voltage the vehicle
is measured when the float voltage has dissapated. Basically, this would
be at staging or at the starting line, where the float charge has had
a chance to dissapate.
To determine your voltage division, simply
measure your pack voltage with a digital voltmeter to the nearest
tenth of a volt. The voltage must be measured before the run.
Voltage classes will be listed with BOTH measured and nominal voltages.
The nominal voltage is basically the historical lead acid design
voltage for that class.
The voltage class conversion will be by a 13.2/12 factor, since
very few lead acid batteries ever go above 13.2 volts once the surface
charge has dissipated.
Effective June 1, 2006 NEDRA segmented the "A" Voltage
Division into 3 seperate divisions to promote more competition and
to expand with new controller and motor technology. The old "A"
Voltage Division was 241 volts and higher. For historical purposes,
records made in the "A" Voltage Division prior
to June 1, 2006 are exempt from the revision. Those record
holders will keep their "A" division records as they are
pending a review by the NEDRA Board since those records are historically
significant.
NEDRA Street Classes went into effect June
15, 2006.
