NHRA Battery question.

[Sunkenkarma]

Alright, so Im getting ready for the dragstrip, getting all my stuff straight. I should be ok, besides the battery, its relocated to the hatch, and it is very securely bolted down with 2 J hooks, but I was reading up on the NHRA rules, and it appears it needs to be bolted down with bolts, not J hooks, and I need a external kill switch. The one thing I want to know, is it an actual rule that you must have a battery box? I couldnt really tell from the posting, Ill put it in here for a reference, please dont flame me, this is the first year that I could get my own car on the dragstrip . lol, Let me know, and most of the time I will be going to commerce.

"All batteries must be securely mounted and may not be relocated into the driver or passenger compartments. Rear firewall of .024-inch (.6 mm) steel or .032-inch (.8 mm) aluminum (including package tray) required when battery is re-located in trunk. In lieu of rear firewall, battery may be located in a sealed .024-inch (.6 mm) or .032-inch (.8 mm) aluminum, or FIA 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. Strapping tape prohibited. A maximum of two automobile batteries, or 150 pounds (68 kg) combined maximum weight (unless otherwise specified in Class Requirements) is permitted. Metal battery hold-down straps mandatory. Hold-down bolts must be minimum 3/8-inch (9.53 mm) if battery is relocated from stock and other than stock hold-downs are used ("J" hooks prohibited or must have open end welded shut.)."

you have the take the J-hooks and weld them shut to the bottom of the tray.
essentially you have to make it so that the only way to remove the battery is by removing the nuts from the threaded part of the j-hook.

i'd like to go to the track with you, wanna pm me your intended dates?

[Sunkenkarma]

Still need to know, do they REQUIRE a box for the battery? Or does it just need to be bolted down?

I'm not expert by any means but I was under the assumption that you needed a box because the battery will vent inside the car.

[phee128]

yea man. you definitely need a battery box with a vent to the outside. i would reloc the battery to the front. You need weight over the wheels if you are going to be drag racing a FWD car. nah mean?
