Product Feeler: Battery Relocation Kit
I’ve come to realize there aren’t many options when it comes to relocating the battery so I made one of my own.
My goals were the following:
Current Specs:
Here are some pics. Please keep in mind that this is my one and only prototype. I was designing and building at the same time so I made a few mistakes along the way. If you see an extra hole or a bent corner, something off center -- just ignore it. The finished product will be much more civilized
I have the time and resources to make more of these if anyone is interested. Let me know and we'll start a list for a group buy!
Now i'm going to go for a drive because my car hasn't been driven in about 3 weeks, and THAT is a travesty...
P.S. – the J-hooks will be seated elsewhere; my J-hooks were too short to put at a diagonal.
Pricing estimated at $199+shipping/paypal
Will set up official group buy if more than 10 people are on this list:
1. L337fpc
2. Zelse
3.
4.
5.
6.
7.
8.
9.
10.
My goals were the following:
- Reduce weight by replacing the stock 37 pound battery with a lightweight Odyssey PC-680 (14.2 lbs)
- Use the stock terminals so no re-wiring is necessary
- Keep the weight as low and as close to the center of the car as possible
- Make the battery bracket rock solid (so there is no vibration)
- Integrate a visually appealing and hopefully functional radiator shield to replace the stock battery tray and intake tray
- Make it compatible with various intakes (including stock)*
Current Specs:
- Weight = 18.2 lbs total with battery (saves 19 lbs over stock!)
- Material = Aluminum
- Finish = Flat black high heat ceramic paint (i'll have to experiment with different finishes)

Looks nice. Any way to get all those wires under the panel though? Maybe swing the terminal connections to the side of the battery and tuck everything neatly under?

I'd have to a see picture from the front but it looks like it won't fit cars with a GReddy kit (or most FI kits, certainly front-mount kits as well) because the charge pipes needs to run in that area.
I put my battery in the trunk. $15 plastic box from AutoZone, some 1/0 gauge power cable, a 4g ground, some terminals, and Home Depot metal. I think it cost me around $100 bucks or less.

Success!
I was able to re-route the wires so they aren't as much of an eyesore. It will take a little effort on your part (although pretty simple) but i think it's worth it.

It might work with some FI. I could imagine more so on the SC side than the turbo side

I did a similar experiament some times back. The pic showed is the material and not yet install.
I don't understand why you make the plate to resist the air flow of the fans, as the original design did. When the fan is on on during idling, due to the space is tight, some hot air will be forced to pass through the radiator sponge and suck back by the rad fan(s). So, when you sprint for a while and meet some traffic jam or something that cause you stop the car, the temperature will raise quite fast. And, the gab around the coolant tank must be covered, because the PCM box has no seal and the hot air will make the PCM + ABS control unit even hotter, and also the AEM alum tubes. I would say the battery location is not bad but the battery itself cost me a bomb at my place. I just use a stand 60amp and put it at the water fluid area, where the original water tank had to be sacrificed and replaced with a modified breather tank. Just FYI, the metal plate surface temperature on my car average about 82 celcius and due to the material I use is not alum or ss, the heat transfer is not that great, so won't feel the heat on the top so much. Rotor housing outer surface temperature average about 82-84 during cruising at 120km/h (stop the car, open the bonnet and quickly get the reading) and 89-94 celcius 160-180km/h @ about 200km. Ambient temp = 30-32 celcius (from noon to evening).
To protect the coil and the aircond pump, I recommend you to make some plate that with curved or diamond edge to block & divert the hot air away.
If you are living in a country that will never have real summer, then your current ideal might be almost perfect, except need to seal off the PCM box.

Looks like the weak point is where the sheet metal bolts to the battery box.
Sure hope it is strong enough and doest crack.
Have you tried it at the track?
rOtor: The tray is in a good position, as it forces the the air into the radiator.
I may be interested.

Good. You have the same intake but it'd be good to test out on other cars just to make sure.
Not sure on the price for just the tray but it would be a good chunk less. I have to nail down my suppliers before i post any prices. The prototype was pretty expensive to make and i don't want to base the price off what this one cost me.
As for the intake i'll check it. It could be wrong but i'm not sure how there is a difference between three identical intake ports.

The area you mentioned is the weak point but it's not that weak. In my original design i had a bracket attach to where the side of the battery box bolted but it was pretty difficult to replicate when i was actually making it. I might try again but the sheet aluminum is pretty sturdy as is.
