thanks for the reply i think thats my next project!

 

Vince, we've started a craze here.

 

this is what a master disconnect switch looks like, both nhra and scca requirer them for battery relocate

scca requirers a different one with a blue sticker

 

Is it in the SCCA GCR or which SCCA rules did you see it in? It's not in the autocross rule book I have, but I believe I have to follow any GCR guidelines as well. Anyway, I suppose it can't be a bad thing. Where do I get one of these? PAW? Pep Boys?

 

This is from the NHRA rulebook:

"Master cutoff switch is mandatory when battery is relocated. An electrical power cutoff switch (only one) must be installed in the REARMOST part of each vehicle and be easily accessable from the outside of the car body. The cutoff switch must be connected to the POSITIVE side of the electrical system and must stop all electrical functions. The off position must be clearly indicated with the word OFF. If the switch is push/pull type, push must be the action of shutting off the electrical system, pull to turn on. Any rods of cables used to activate the switch must be minimum 1/8 inch diameter. Plastic or keyed switched prohibited."


keep in mind- you cannot simply hook your positive battery cable to the cut off switch. The car will continue to run if you disconnect the battery. You must also tap into the power to the ECU relay to be cut off as well, from the same switch, so the car will stop running when the switch is used.

 

don't know if local shop will have them, but places like jegs, summit racing etc will

 

i wanted to do a battery relocation too, but that would take me out of stock class as well..like the other person said, im not quite ready for that yet

good job with the write up urban!

EDIT: btw, did u weigh the battery by any chance??

 

Vince said 35-40 lb, I was gussing 40

 

thats one heavy *** battery..

brian, i was wondering what the SCCA rules were to getting a lighter, maybe smaller battery but without relocation?

 

Here's a listing of the autocross rules online: http://moutons.org/sccasolo/

It seems that a lighter weight battery is not allowed in stock category, but STS and SP categories allow them. Rule 14.9.B and 17.9.A "The make, model number, and size of the battery may be changed but not its voltage."

 

hmm ok. well id like to stay in the stock class for now, screw the battery relocation

 

So Brian u feeling any difference/improvement in handling yet?

 

not bad.... something to think about doing in the future

 

It seems to make a difference, but given it's about a 4% change in CG it's probably in my head Who knows.

 

well now instead of 60/40 weight distribution it's about 58.5/41.5 weight distribution..better than nothing tho hehe
