I want to know if anyone has relocated their battery to the truck without drilling any holes and how do you have it routed?

Ooops, trunk not truck.

from inside the engine bay theres a biiig hole on the passenger side that the main bulk of the electrical runs through the fender. Ran it through there, actually secured it to the body inside the gfx, out the back of the GFX up through the rear wheel well and through two holes into the back right of the car where the battery will be.

in retrospect i aaalmost secured the wire well enough to keep it safe from the back tire, but not quite, tire hit once and rubbed right through.

when i do it again itll just be through the firewall and under the carpet to the back. thatd be the smart way to do it lol

Ya I did. I used 3 4 gauge wires hooked up directly. to the starter for the pos. I hooked up the neg. to 2 switch on the bumper for a quick disconnect switches. I got two gell pack batterys. I only drilled new holes for the battery mounts. I put the wires through the firewall through the heater hoses openings. I took out the heater but you can put it through some of the other rubber garments. I have more pictures. check out https://www.thirdgen.org/forums/body...res-my-ta.html

is all this work just to clean up the engine bay or is there a functional reason behind moving the battery. come to think of it my saturn ion has a battery in the trunk, right behind the spare tire under the floor. i still dont know why but it does make for easy intilation of audio equipment.

there are a few resons to move it to the back. One is in racing you want the most traction you can. and moving 2 giant batterys to the back puts weight on the rear end to help you. it does clear up space up front. And its cool that you can modify something that not menny people have.

firstly our cars are way heavier in the front hten the back, doing so brings you closer to 50/50 weight distribution

also for the purpose of drag racing, it helps to have weight in the back right corner of the car, due to the direction that the crank/drive shaft spin your car always torques over more one way from a launch. The battery back there helps keep weight where you need it, thats why its always in the back right

Good info..........I just bought a BMR battery relocation bracket for the rear to mount my optima.

Project, are you going to drill holes? Let me know how you do it and how it turns out. Just got me an optima, that is why i want to move it since i wont worry about any leaks.

I won't be doing mine for a few months. There is a picture of the bracket on the BMR web site. You just drill the holes on the lip and use self tapping screws.

It might interfere with the spare battery though. No matter a CAA (AA) membership and a cell phone does wonders!

that bmr piece is no good for the track tho eh? if its in the back of the car it needs to be in a sealed and vented box.

Its ok to use with a sealed battery like a optima, but NHRA rules still require a firewall between the battery and the drivers compartment. That hatch well cover that came in some models is acceptable as a firewall.

I Have built a cover for the trunk. I will put up pics. untill then read this about the track rules of NHRA

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

i recently did it with the plastic battery box. Had to enlarge the spare tire condensation or drain hole whatever you call it for the vent tube. It doesn't matter for me yet though no engine/tranny/ or interior back in the car yet
