|sedanbob||To minimize voltage drop over the distance, I suggest 1/0 welding cable. Run from positive to starter, and negative to a bolt on the bellhousing. As was suggested, support it along the way, and protect it anywhere it goes through a hole or by a hard edge. Use 8 gauge from the alternator to the starter. Run grounds from the bellhousing bolt to the chassis, and chassis to body. The welding cable is fine wire so it's nice and flexible. I crimp and solder lugs on the ends, and cover the joint with heavy duty shrink tube. A battery disconnect switch is a good idea, as are auxillary battery terminals under the back of the car, near the battery.|

This is my setup in the rear of my 3rd gen Camaro.
Battery box is a Summit piece, with vent tube.

I relocated my battery and installed the solenoid alongside it using MadElectrical´s kits.

|farmwalker||Cool guys. Thanks for all help. I think I know what I want to do now. All of your advice was helpfull. I like the idea breakers instead of fuses too.|
|01-05-2013 10:20 PM|
instead of fuses u can buiy circut breakers from any real car audio place thse things come in 100/150/200/250/300/400 amp , the big fuses starting at 100 amp and up run about 22 bucks each and arent easy to find if u happen to pop a fuse and need a new one
the big circut breaker should run about 50-100 bucks and ull only ever need one most of them will accept 0 gauge cable directly and some even bigger
if u buy car audio amp cables be sure to buy high quality cables
good 8 gauge car audio cable will out perform cheap car audio 4 gauge

10 is stock and may work but 8 would be best for alt wire. If you have a lot of assesories you may want to use high quiality 8. You can buy a amp installation kit with fuses and wire pretty darn cheap might be the cheapest simple solution
One wire is fine unless your going to use a solienoid kit and not run full voltage on the larger wire all the time. There is no difference electricity always takes the path of least resistence.

Ok. So this is what I think I'm going to do.
2 Gauge wire with a 250 AMP fuse to a cut off switch. Then from the switch I'll run a 2 gauge wire to the starter and a seperate wire as well from the switch to the alternator with a 100 AMP fuse. (I'm doing this because I've heard it's better to run a seperate wire and since I'm doing this, I figure I might as well do it the best way the first time.)
But what size wire do I use to run to the alternator? It doesn't have to be any where near a 2 gauge for goodness sake, right??
Also whats the highest compression ratio I can have before I cant use my stock starter?

If that works for you then putting the relay next to the battery will work as well. Then the heavy guage wire does not need to be hot more thana few inches past the battery.
But with high compression engine you may need to run a disconnect or a larger relay and mini starter.

|vinniekq2||use welding cable,works great.Also run 2 grounds.one to the frame and a separate wire to the block|
|01-05-2013 07:18 PM|
Yes, use thicker wire as distance is longer.
I used 00 inclosed in a rubber garden hose inside frame. Grommet openings.
I also used a 250 amp fuse back by gel battery.

The fuse would need to be pretty big one. Race cars use a kill switch located in the rear trunk panel so it can be access from outside the car. Also have it close to the battery. That way you can just turn the switch when you get out of the car. Also rules for most faster drag cars.
Also you can just run the alt wire to the starter relay. Do you plan to use a ford style solenoid kit on the firewall to start the car.

Main power should be on a relay. You can use a fuse for the mains but depending on the system you may need a pretty big fuse. Again i would go with the stereo install type 50-100 amp fuse. At 100 amp it could still badly burn wires but a dead short will pop it instantly.
Also be sure to cover the wires with shrink wrap and a loom. And run the under the car inside the frame rail tied every 12 inches with zip ties or bolted down insulated clamp. Make sure it does not run thru any hole that is not covered by a groumet.

Battery Relocation Quesions
I'm going to be relocating my battery to my trunk in my 77 camaro and I know what to do about a box and venting it. What I'm wondering is what gauge cable should I use for the cable to the starter and what guage wire should I use for my charging wire?? Also what size fuse should I use for both the starter cable and the charging wire?
