I was thinking of the rear seat delete

Modular Mustang Racing

PT 900500

and

PT 900750
Upgrade Rear section to Aluminum (NHRA approved firewall)
With this option battery does not need to be inside of box (carpeted on passenger side for factory look)



So to be track legal I would not have to put my optima in a box? I have a billit hold down for it now, I would just have to add the battery kill switch somewhere in the back?

Something didnt sound right about that, but I know nothing about track rules I have never been to a track, just autocross and dyno pulls...

First you wouldn't need to put an optima battery in a box since they are sealed and can even be run upside down. And I wouldn't buy a rear seat delete from then. Get it from Scottrod, guy sells some nice aluminum pieces!!!

Thats for regular acid batteries, optima are exempt from that rule.

Maybe the tech at your track allows it, but that isn't the case at any of the NHRA tracks I've run at. Nowhere in the NHRA rulebook does it say that sealed batteries are exempt.

What do you think a battery box turns a regular battery into? A SEALED battery....

Agreed. But point out the line in the rulebook that says you can run a sealed battery without an approved box or firewall. The rule doesn't have any special requirements or exemptions for the type of battery. "All batteries..." is pretty all-encompassing.

a sealed battery means you can run a battery tray that is capable of bolting to the floor with 3/8" bolts, which you can get for about $50 :)

Like I said before...not at any of the NHRA tracks I've run at. If you're able to pass tech though, more power to you.

Aluminum Engine Bay Panels, Rear Seat Deletes, Door Panels, and more for your Mustang

They cost $275 though. I can make you one for $100-$160 but it wont be aluminum. I use MDF or a PVC composite which only weighs about 15 lbs
I would rather spend the extra 100 for the aluminum :)

I have certification to 7.50s with a non sealed box
