I would be using a electric water pump so I don't have a meltdown. So I guess this battery wouldn't be enough then?

The last thing you want is a 30lb battery floating around the cabin during a catastrophic event.

use 1-0 welding cable for the leads to the front starter. There is room to route through the wheel well and under the door frame.

The LPE example in the center pocket has adequate access to structural framing, however in this location the CD player has to be relocated.

My first attempt at the Battery box:

Cable is routed through wheel well to rocker panel.

I like how invisible this setup would be! Im wondering though, have you ever had your car out to the track? Would they allow this because its a gel battery, or no?

I dont think so,
The rules I saw suggest that this would have to be sealed , and there needs to be a 100% kill switch in plain view on the rear face.

Here is the info I found.

All batteries must be securely mounted. Batteries may not be
relocated into the driver or passenger compartments. Rear firewall
of .024-inch steel or .032-inch aluminum (including package tray)
required when battery is relocated in trunk. In lieu of rear firewall,
battery may be located in a sealed .024-inch-steel, .032-inch-aluminum,
or NHRA-accepted poly box. If sealed box is used in
lieu of rear firewall, box may not be used to secure battery and
must be vented outside of body. Relocated battery(s) must be
fastened to frame or frame structure with a minimum of two 3/8-
inch-diameter bolts. ("J" hooks prohibited or must have open end
welded shut.) Metal battery hold-down straps mandatory.
Strapping tape or Electrical zip ties prohibited. Stock unaltered battery
boxes / trays with OEM hold downs permitted only in stock location

Master Disconnect Switch:
Whenever a battery is relocated to the trunk, the vehicle must be equipped with an external disconnect switch. This switch must be clearly labeled and immediately disconnect the positive side of the battery. To determine if the switch operates properly a tech inspector will turn off the switch with the engine running. If this action does not shut down the engine then the switch is wired improperly and the vehicle shall fail the inspection. Drivers should ensure the alternator charge wire is routed to the battery side of the switch. This isolates the alternator from the rest of the electrical system. Drivers should check with the switch manufacturer to ensure it is properly installed.
