To the people who drag race/ familiar with NHRA rules
 

What constitutes a "battery hold down?"

In the past, I may have looked at this rule.... and used my interpretation of it.... :) Zip ties RULE!

But.... I think I should make the car more "legal."

I am relocating my battery a little father back in the engine bay..... about 2 1/2 feet back... and I am limited on room.

I plan on mounting it to the frame rail... and have a metal strap over the top.

I wonder if that is legit?

my understanding is basically that it jsut has to be held firmly in place. i have seen metal straps, belts, and stock style hold downs used lots of times on relocated batts.
just get it secured in a way that it doesn't move around if you tug on it and you should be good

Zip ties keep it snug ;)

If it looks half-assed they will fail you, the rule can be subjective.

what about relocating it to the rear of the car?

probably nitrous getting in the way

i say a strap would suffice, but i dont know **** so dont listen to me

Wat if u put it inplace of ur passenger seat? Just bolt it down to the floor.

If you have a hatchback you will need a firewall between the battery and the trunk. You cannot have it in a passenger compartment.

all relocated battries have to be secured to a frame rail threaded rod can be used but it cant move at all ---- some tracks check---- if u pass island you can race anywhere in the USA --- jz

Ok, cool.

I had the set up in the trunk area many years ago.... but ran into too many charging issues when I went with the dual bottle/ warmer set up.

This will still be in the engine bay..... just in place of the heater core.

Pic's to come

Thanks!

uhhh, yeah.. what they all said.

and if its relocated to the trunk you also need to have a on/off switch on the back of the car...


any other questions, ask johnjzjz... he's smarter than me ;)

You can if it's in a sealed (but vented to the outside) box.

Vega type cars put the battery in the trunk but its below the floor w/ a door access ---- jz
