Fuses, Circuit Breakers or nothing at all?

TAZLDAZL said

I just wanted to thank everyone for the replies. I am definatley going to use some sort of fuse set up. Some of the guys that I know that have been racing their whole lives are still old school die hards. If a fuse causes me to loose a race oh well I still have a car to race in and not a burned up piece of junk. Most of the wire I have is all 10-14 Ga. so I should be all right their. I have also used OO Ga. for my battery runs from the trunk to the engine compartment.
Thanks again for everyones support & coments

Yeah, here's the thing I was getting at earlier. In your case, you need sort of a "last ditch" effort to prevent fire

Use wire that is WAYYYY oversized.

Don't worry about protecting the load, just worry about protecting the WIRE. this means, say, that if you have an ignition drawing 10-20A but you use wire sized for double that, with a 40-50A fuse/ breaker, all you are protecting is a wire short

A popular suggestion for trunk mount batteries, is to use a purpose cheap aluminum ground cable --short as possible--which will act like a fuse if the main cable shorts.
