how will anyone find it?


Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

Rulebook states it must be on the rear.

If you are going for invisability, usually tyhe best bet, is to use a push/pull type of switch. Run the bar in through a very small hole.

Then remove the bar when you aren't at the track. Although, you have to have it labeled "push off" or something like that, so you may have to add a label when ravcing too. Very commonly done on street strip type cars.

From the website FAQ

http://www.nhra.com/contacts/tech_faq.html


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.

You also need a fire wall now between the passenger compartment and trunk.

A sheet of metal at the speaker tray as well as behind the seat will work.

minimum .024 inch steel or .032 inch aluminum
