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.

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...)

I guess I'm just a party-pooper. (IMG:style_emoticons/default/slap.gif) I thought the factory did a pretty damn good job placing the battery. It partially offsets the drivers weight and it's almost centered in the middle of the car. It doesn't suck up any trunk space and wiring is a piece of cake. I can't for the life of me figure why the big urge to move it especially with the light weight, leak resistant batteries available today. (IMG:style_emoticons/default/confused24.gif)

Yes, the hell holes are a direct result from batteries but that issue is almost totally resolved with today's batteries

Can anyone honestly say they moved a specific battery to a trunk and got a reduced time in a race or noticeably better performance?

the move show's up on a set of scales.
I don't know that consecutive laps have ever been run with both set ups... on the same day, same place, same weather, same car....

but it will show up on scales

and racing is a game of very small improvements
(the factory built mag cases over earlier aluminum ones for a savings of less than 20lbs and to help the corner balance of a tail heavy car)

Brant, honestly I can't argue that response as it's certainly true and accurate....but I can eat a Big Mac and it shows on a scale.... (IMG:style_emoticons/default/av-943.gif)

Point taken....I could better understand it if it was on a fully stripped race only car where the pounds moved around are a higher percentage of actual car weight but most of the moves I see are far from that. The corner balance on the scales may look better but it depends where the weight is located to truly make a difference and the point I'm trying to make. It just seems like moving weight further out, especially to the rear would tilt the scales the wrong way.....
