battery in trunk dragstrip rules?
 

what are the general rules for puttin the battery in the trunk.

does it have to be vented to the outside?

Re: battery in trunk dragstrip rules?
 

i think the actual rules say its supposed to be, but by me they dont check ----

I've heard of guys not being able to race due to there not being a master kill switch, I installed one in my taillight and hook it up when I go to the track

johnny we got bugged about this at PIR for Alec's car.

Has to have a kill switch (he just uses a little toggle switch on the back bumper to kill battery supply via a relay, and unplugs the alternator before tech inspection (plugs it back in after tech)

also they say it has to be in a battery box. alec has a plastic marine one but PIR gave him a little flack about that, says it has to be a summit style aluminum one secured down.

Re: battery in trunk dragstrip rules?
 

I heard they look for only two things:

- Kill switch
- Battery Box mounted Correctly (i.e. Won't move around a lot)

As far as venting, as long as your box has holes that look like vents. But that's here in San Diego. I dunno about any other places.

So Cal gets sweated every time at Fontana. What they've told us......

Battery box can't be plastic (marine type) Never heard anything about having it vented.

Cutoff switch has to kill all the pos+ and the alternator ma-bobber so it kills the car.

They always give us ---- for having a HELLA plastic shut off. They say it has to be metal.

Mount it good, and I think that's all I've ever heard (multiple times. lol)

Re: battery in trunk dragstrip rules?
 

well heres my deal.

i got the box secured to my trunk like a mofo. with 4 9/16ths bolts, i think im good there.

the vent i will just drill a hole in the bottom.

i DO NOT want to punch a hole for a kill switch on the back of my car. but i guess i have to? :(

with the relay thing, how does that work? what do i get to use it.

does it just tap into the main + cable and then to a little switch?

thanks guys. i ------ hate techin, they always bust your balls.

Re: battery in trunk dragstrip rules?
 

yeah the relay is just a box that your main hot lead runs thru, and you feed a basic toggle to it too.

gotta pop that hole in the back tho, no getting around it.

alec did his under the bumper, you cant really see it.

Re: battery in trunk dragstrip rules?
 

well i guess i'll have to do it!

---- id rather blow up with my battery funes then go through all this crap ;)

Re: battery in trunk dragstrip rules?
 

what do you guys mean by "punching a hole" ? well let me rephrase it, why do have to make a hole?

Re: battery in trunk dragstrip rules?
 

he's talking about making a hole to mount the kill switch.

Re: battery in trunk dragstrip rules?
 

yah, but why does the kill switch have to be outside of the car?

Re: battery in trunk dragstrip rules?
 

because if you're on the strip and the emergency crews need to kill the battery to kill the motor in one of those bad situations, i doubt they'll wanna jump in the car and flip the switch.

example, lets say you lose control, nail the wall, and roll the car...they're gonna rush out, and kill all power before they start messing with getting you outta the car.

Re: battery in trunk dragstrip rules?
 

how do you hook up a relay fook?

mines got two big posts...

and two little posts.

Re: battery in trunk dragstrip rules?
 

I think that you ahve to have an approved box also.

It has to be mounted in a certain way. You can get the NHRA specs on the web.

Re: battery in trunk dragstrip rules?
 

You hope they kill the power. Look at the burning DSM, no one hit the kill switch, fuel kept pumping!

Re: battery in trunk dragstrip rules?
 

All you need is:

-sealed box
-vent tube
-bolted with 7/16 inch bolts
-kill switch

Re: battery in trunk dragstrip rules?
 

I've never figured out the easiest way to do the alternator cutoff, but start the car and turn the switch off, and the car has to shut off. Maybe unplug the alternator during tech or take the belt off. :-\


A write up on the correct way to hook it up would always be good too.

Re: battery in trunk dragstrip rules?
 

use the ignition signal or the + wire to the coil. pretty easy to do.

Re: battery in trunk dragstrip rules?
 

now you tell me -------!!!!!

Re: battery in trunk dragstrip rules?

Re: battery in trunk dragstrip rules?
