I have a
street car that I occasionally run at the strip. I've relocated the
battery to the rear. What else do I need?
Any car with a relocated battery must be equipped
with a master electrical cutoff, capable of stopping all electrical
functions including ignition (must shut the engine off, as well as
fuel pumps, etc.). The switch must be located on the rear of the
vehicle, with the "off" position clearly marked. If the
switch is of a "push / pull" type, then "push"
must be the motion that shuts off the switch, and plastic or
"keyed" typed switches are prohibited. Also, the battery
must be completely sealed from the driver and/or driver compartment.
This means a metal bulkhead must separate the trunk from the driver
compartment, or the battery must be located in a sealed, metal box
constructed of minimum .024 inch steel or .032 inch aluminum, or in
an NHRA accepted plastic box. In cars with a conventional trunk,
metal can simply be installed behind the rear seat and under the
package tray to effectively seal the battery off from the driver. In
a hatchback type vehicle the battery box is usually the easiest
solution, since the alternative is to fabricate a bulkhead which
seals to the hatch when closed. At present, Moroso is the only
company which offers an NHRA accepted plastic battery box, part
number 74050.
