IMO it's so hard to make a FFIM look right on a 7M, and I've still never seen anyone with proof that there's any actual benefit that can't be gained with the regular manifold. (Unless someone out there has a 100mm throttle body or something that couldn't possibly fit on the stock manifold, and is using 4" piping from the IC, but I've still never seen it on a 7M.)

I'd use the space for the circuit breaker that you need for the big wire run back to where the battery is. Possibly I'd leave a small fuse box to be used for other potential 12V circuits under the hood, something that you can feed a nice fat wire, and run a handful of 10-20A circuits off of for other goodies under the hood, or even in the cabin. Maybe put in a couple pr relays for ignition or even accessory power. Make it look OEM and have a proper fuse box for your remote car starter, piggyback computers, extra audio stuff, 120VAC inverter, extra fuel pump relays, instead of some ugly in-line fuses which are impossible to find under the steering column or scattered around the car at random. It would certainly make future electrical problems easier to locate and diagnose, and future electrical modifications easier to loom into a wiring harness and document.

And, if you've still got space left... The main point that people relocate a battery for is weight distribution. Air is about as light as it gets.

Any other ideas as to what to do with the space?

The only reason you should relocate the battery is because you need the space...

Sorry, you're 100% completely wrong and it's been proven MANY times over that a FFIM is a massive gain.

The main reason should be because you need the room.


Look people, working around autoparts, what do you think the most dangerous thing in my store is? The batteries. Their toxic by their very nature (lead + acid). They also vent toxic and flammable gasses, and have the potential of a bomb.

At the very least, they need to be well secured within a sealed box with an external vent to the outside.

Proof can be seen in the pics of my old Z car...

Interior of the car was covered in acid after the crash that killed it and me..

Lots of answers here. Thanks everyone. The relocation kit includes an aluminum box, 15 feet of 1 gauge red wire, and 2 feet of black, connections, securing straps, etc. The box will be secured to the floor, fabricating a bracket to the rear seat belt mounting points. It's vented; although, I don't think that makes any difference using an Optima battery. They aren't "gel" batteries; but, "AGM", absorbent glass mat. They claim "virtually spill-proof".

FFIM is out. I researched that years ago and made the decision not to go in that direction. Not sure how much "extra stuff" will be required under the hood. The battery cut off should be reachable from the driver's seat, so it won't go up there....

I spent ten years in auto parts. Never once had issues with batteries in the stock room. Sure, they're dangerous, yes. I talked with a trash truck driver who told me that a battery in his truck, when the trash was compressed, would turn the truck into a bomb. I'm not sure I believe that... there are enough evil people in this world that you'd be hearing about it all the time. At any rate, I didn't dispose of my old battery that way.

Two fire extinguishers are on the shelf to be mounted close to the driver... away from the battery... and at the moment, I have little idea what I will do with the space other than prep it and paint it.

IJ., that sounds awful! I'm sorry to hear that it "killed you", too. I hope the land down under is Australia, not a grave :)

Thanks again for all the ideas.

I got better ;)

Batteries were in Marine Boxes Vented to the exterior of the car, one Shattered on impact the other went out through the Hatch, the Miracle in all this was the car had just been topped off with 120L of fuel, rear suspension arm sliced through the fuel tank and no fire...

I managed to kill the battery isolator before impact.

Ya I used the space for ffim and there are plenty gains, one being a not pain in the arse way to do spark plugs :D

Shame bout your car there Ian :/
Pretty serious accident, is there anything you could have actually done with those battery boxes?
