Battery in trunk, More on my 914 / Ax project car Options

[bfrymire]

Always seems to be something fix or upgrade. Neverending. But, we all like that right?

So, I wanted to move the battery into the trunk, and at the same time, use a AGM battery (26lbs vs 36lbs).

Well, here it is mounted using the billet mount. The PO cut a hole in the trunk for starter access, so, I decided to put this to use. (Yes, I do plan to clean up the hole.)



Someone else did something simliar, and I had asked about the wires that normaly attach to the positive post. So, I used a battery bulkhead connector and attached the wires using that. You can see it in this photo next to the petronix.

Here's the post unmounted.



Inside engine bay.



More in next post....

(Still have to fix that big hole in the firewall, put new bars and shocks in the front, and fix an engine miss. <sigh> Don't think I am going to make the AX this weekend...)

It's been 5 years since I stuck this here. @11lbs you can put it where ever you want. I could have put it in the front trunk but the cabling would weigh as much as the battery. (IMG:style_emoticons/default/dry.gif) This makes for very convenient runs for the various wires....like the main feed for the MSD & starter/charging. Bout ready for a new one, me thinks.

Part of what I am working toward is a ligther car, and simplification. Short wires = both.

I do like your placement better than mine, and that is an easy fix.

As far as heat from the muffler, probably still less than being in the engine bay. I can place a probe and measure it.

With the lid on, it gets REALLY hot, much hotter than the original location. The Cap'n

(IMG:style_emoticons/default/agree.gif) with the Cap'n. I mistakenly left a Tyvek car cover in the trunk for a track event, and areas touching the trunk floor melted.

My battery is mounted in the front trunk like Elliot's above, only difference is I use a small battery similar to this to save weight.

I'm using the welding cable approach as the Cap'n suggested and have no issues what-so-ever with this setup. The cable adds weight, but it is as low as you can get and in the middle of the car.

Hope this info helps. Just trying to share a successful setup and lessons learned with the car cover in the trunk.
